LevelRay and EU RED Cypber security

The LevelRay non-contact level sensor is one element of a flow monitoring system. The cybersecurity of the LevelRay will be affected by the cybersecurity of the entire system. The following describes the features related to cybersecurity as well as the responsibilities of the end-user to maintain it. In general, the best way to maintain the cybersecurity of the system is to physically protect the system from tampering. The LevelRay sensor’s enclosure is hermetically sealed and therefore tampering of any  LevelRay hardware would require the enclosure to be physically broken and destroyed before tampering could happen. This section will explore the security of several aspects of the LevelRay device, but the user is cautioned to examine the entire system.
Bluetooth®
The LevelRay implements Bluetooth Low Energy (BLE) v5. Communication. When a smart device is paired, communications is encrypted according to Bluetooth Low Energy specifications. Pairing may require user interaction. Any Bluetooth enabled device can connect to the LevelRay and ascertain high level device information such as model and serial number. The communication between the host and the LevelRay is encrypted using 128-bit AES-CCM.
The BLE GATT services available are:

• Bluetooth standard device information service: 180A
• Teledyne Authorization service:
  081ba3f6-f64a-4f5b-bfef-416a8a0ebc28
• Teledyne LevelRay service:
  d43a8bee-d71a-484d-9df2-9f321f9b7632
• Teledyne TIEBus service:
  b46a5229-507e-4989-b9cb-a882fd18538a
• Nordic DFU SMP service:
  8D53DC1D-1DB7-4CD3-868B-8A527460AA84

Measurement and setup information via LevelRay services cannot be acquired without authorization. The LevelRay uses a challenge-response authorization scheme utilizing a 6-digit passcode and a procedure that never transmits the authorization code. Instead, a SHA-256 cryptographic hash of the passcode along with exchanged random numbers using the Arm Crypto Cell True random number generator, are calculated on both the host device and the sensor.
If those hashes match, then the host is authorized. This authorization scheme mitigates against replay attacks gaining improper authorization.
Every device has a unique passcode that is printed on the label attached to the LevelRay. This passcode cannot be bypassed, but it can be changed by the end-user.
Wireless communication interference
The Bluetooth option in the LevelRay is used to connect to dedicated apps on mobile devices to configure the LevelRay, and to acquire measurement data from the LevelRay to the mobile device. Further handling of the data on the mobile device is up to the user’s discretion. The LevelRay operates in an unlicensed ISM band at 2.4 GHz where any third party can intercept the radio waves, willfully or accidentally, for any unknown purpose.
In the event this product is used near other wireless devices such as microwave and wireless LAN, which operate on the same frequency band as this product, there is a possibility that interference may occur. If interference occurs, stop the operation of the
other devices or relocate the LevelRay away from other wireless devices before attempting to use it
Modbus/TIENet – RS485
The RS485 interface has no inherent protection from a cybersecurity standpoint. The LevelRay uses the Modbus RTU Application Protocol over the RS485 interface. This is an open protocol with no cybersecurity protection. This allows the RS485 to be used with any Modbus compliant computer or controller. As such, it is the responsibility of the end-user to physically secure the RS485 interface from being tampered with or destroyed.
Non-Volatile Storage
The LevelRay has flash memory which contains the operating firmware as well as device configuration settings. This data is protected from being read or written by the microprocessor, but their contents are NOT encrypted. All cryptographic digital assets are stored in the microprocessor’s key management unit (KMU) which are not readable to software and to other hardware components. It is the end-user’s responsibility to physically protect the LevelRay from bei ng destroyed and potent ially allowing the underlying components to be tampered with.
Firmware updates
The LevelRay firmware can be updated, but only updates supplied by Teledyne ISCO will operate. The firmware update files are not encrypted in any way, but they are cryptographically signed using the Elliptic Curve Digital Signature algorithm, ECDSA-256. This ensures that only signed firmware from Teledyne ISCO can be used with LevelRay. Should someone try to change the firmware update binary or try to load their own binary, that firmware would not run on the LevelRay, and the previously installed firmware will continue to operate.
Firmware updated via Bluetooth is encrypted in transit, but firmware sent via the RS485 interface is not encrypted. However, without a proper signature, modified firmware will not run.
Cipher GO!
The Cipher GO! application is digital ly signed by Teledyne Instruments Inc. The application will store and use an encrypted version of the LevelRay passcode, so the end-user is cautioned to protect access to the device running Cipher GO! with a user password or biometric security.

Section 1 Introduction

The Model 370 LevelRay non-contact radar level sensor, a TIENet device, can provide liquid level measurement to the DuraTracker® flow meter. The flow meter has built-in level-to-flow conversions that cover most open channel flow measurement situations.
1.1 Description
Teledyne ISCO’s LevelRay non contact radar level sensor uses the FMCW (Frequency Modulated Continuous Wave) method to measure liquid level. Mounted above the flow, the sensor sends a linearly frequency swept radar signal and receives the reflection from the liquid surface. The slight time delay between trans-mitted and reflected signals creates a beat frequency proportional to distance, allowing the device to calculate level accurately. This non contact method minimizes maintenance and performs reliably in applications with chemicals, grease, silt, or suspended solids.

This non-contact measurement method reduces the frequency of maintenance and is ideal for applications where the flow may contain chemicals, grease, silt, or suspended solids.
1.2 Model 370 LevelRay Sensor Design
The radar level sensor consists of a housing with a radar module that is both signal transmitter and echo receiver.
The Model 370 LevelRay is available with a 10 m, 23 m, and 30 m cab le lengths with connectors. For greater di stances, external connection via conduit, and connection of additional TIENet devices, the TIENet expansion box is available. Bulk TIENet cable may also be used for greater distances.

1.3 Operation
The sensor operates at 60 GHz using the FMCW (frequency-modulated continuous-wave) method to determine the distance from the sensor to the surface of liquid. The LevelRay then calculates the liquid level and sends it to the DuraTracker to calculate flow.
WARNING
This sensor has not been certified for use in “hazardous locations” as defined by the National Electric Code, by the IEC, and by the ATEX directive.
WARNING
The installation and use of this product may subject you to hazardous working conditions that can cause you serious or fatal injuries. Take any necessary precautions before entering a worksite. Install and operate this product in accordance with all applicable safety and health regulations, and local ordinances.
1.4 Maintenance
If the device is used properly, no special maintenance is required in normal operation.
In some applications, buildup on the radome can influence the measuring result. (The radome (Figure 1-3) is the semicircular enclosure at the bottom of the sensor that houses its radar antenna.) Depending on the sensor and application, take measures to
avoid heavy soiling of the radome. If necessary, clean the radome at certain intervals.

Clean the sensor with water and a soft cloth while ensuring that the LevelRay housing radome and (on some LevelRay sensors) the pressure transducer grate is clean of debris.

Section 2 Installation and Setup for the DuraTracker

The DuraTracker does not have to be mounted near the flow stream. You can install the flow meter itself at a convenient, protected location and route the sensor cable to the measurement point. Proper installation of the Model 370 LevelRay radar level sensor is critical for accurate measurement.

2.1 Sensor Installation Considerations
Measurement accuracy can be affected by several site factors that should be taken into consideration when selecting the location for the sensor. If the sensor cannot obtain a valid reading, an asterisk (*) appears next to the displayed level, indicating that there is an error.
2.1.1 Beam Angle
The LevelRay sensor has a ≤8° beam angle, forming a cone whose apex is the center of the LevelRay housing radome, the semicircular enclosure at the bottom of the sensor that houses its radar antenna. The sensor can best detect surfaces within this cone; detection of surfaces outside of this cone is greatly attenuated. Narrow channels can result in false echoes and incorrect level readings off of the walls, obstructions, and sides of the channel.
2.1.2 Humidity
The sensor can operate in conditions of extremely high or low humidity. Water droplet condensation buildup on the sensor’s bottom surface will slightly attenuate the signal, but it will continue to perform.
2.1.3 Surface
Solids, foam, oil, and turbulence can all absorb or weaken the radar return, causing errors in detection. Foam and oil on the surface of the stream can produce false level readings.
2.1.4 Temperature
If the sensor will be installed outdoors in direct sunlight, use of a sunshade (not supplied) can help to prevent overheating of the sensor housing.
2.1.5 Waves
Waves on the surface of the flow stream can deflect the radar signal, causing erroneous readings or total loss of signal. The DuraTracker software can reject occasional readings that deviate substantially from normal.
2.2 Connecting the Cable
WARNING
Carry out electrical connection by trained qualified personnel authorized by the plant operator. Only connect or disconnect in de-energized state.
The Model 370 LevelRay radar level sensor connects to the DuraTracker flow meter in the same manner as other external TIENet devices. Such connections usually use conduit for permanent mounted meter or a TIENet receptacle for portable meters. Multiple external TIENet devices can be connected simultaneously.
Refer to the DuraTracker Flow Meter manuals for instructions for accessing the instrument’s interior components.
2.2.1 Connecting to DuraTracker via a TIENet Receptacle
The optional external TIENet devices all scan the hardware in the same manner. A scan is required anytime a new TIENet device is added.
The following TIENet devices will attach to the TIENet receptacle:

• 370 Radar Level Sensor
• 310 Ultrasonic Level Sensor
• 350 Ex Area Velocity Sensor
• 301 pH Interface
• 360 LaserFlow Velocity Sensor
• 306 Sampler Interface
• 305 SDI-12 Rain Interface

O-ring and lubrication forthe TIENet receptacle

1. Coat the O-ring’s sealing surface with a silicone lubricant.
   CAUTION
   Do not use petroleum-based lubricants. Petroleum-based lubricants will cause the O-ring to swell and eventually deteriorate. Aerosol silicone lubricant sprays often use petroleum-based propellant’s.
   If you are using an aerosol spray, allow a few minutes for the propellent to evaporate before proceeding.
2. Align and insert the connector. The sensor release will “click” when the sensor connector is fully seated.
3. Connect the two caps together.

2.3 Sensor Installation
The mounting location of the LevelRay sensor depends on the type of primary measuring device (such as a weir or flume), and on the method of level-to-flow conversion used in the DuraTracker. Refer to the Isco Open Channel Flow Measurement Handbook or to instructions provided by the manufacturer of the primary device for detailed information about locating the measuring point.
If you intend to measure flow by some other means, such as a gravity flow equation (Manning) or by calibrating a section of the flow channel, you must locate the measuring point on the basis of the hydraulic characteristics of the channel as well as the level-to-flow conversion method.
In most open channel installations where the level may exceed one-half of full pipe, mount the sensor to be as near as possible to the midpoint between the entrance and exit to measure over the least turbulent flow.
2.3.1 Dead Band
The radar sensor does not have a dead band and can measure liquid level all the way to having liquid touch the LevelRay housing radome. However, accuracy decreases within 150 mm range of sensor, so a minimum distance greater than 150 mm is recommended for best results.
2.3.2 Sensor Measuring Range
At ranges greater than 150 mm of the radome, level readings are accurate within 4 mm (that is, 2 mm to either side) of the center of the radome.2.3.3 Submersion and Fouling 
Fouling by grease or solids can cause the sensor to malfunction. The sensor is sealed, so unless it was exposed to corrosive substances, temporary accidental submersion should not harm it.
Upon retrieval, the sensor should return to normal operation, but if sensor readings are impacted, the sensor may require removal of debris. Clean the sensor with water and a soft cloth while ensuring that the sensor housing radome and the pressure  transducer grate is clean of debris.
The level measurement will switch from radar to pressure transducer when the sensor is submerged and continue to provide level measurement.
2.3.4 Leveling
The sensor reports its X- and Y-axis orientation to the DuraTracker or other devices as positive or negative numbers, accurate to within ±3 degrees.
These readings are explained in Figure 2-2:Changes in X- or Y-axis values may indicate that the sensor has moved during, for example, a surcharge event.
2.3.5 Mounting Options
The Model 370 LevelRay sensor can be mounted over the flow stream in various ways, depending on which method best fits the application.
Optional equipment is available from Teledyne ISCO for wall, floor, suspension, and scissor or spring ring mounting (see Section 1.6, Accessories). The sensor has a mounting plate that allows it to attach to the equipment listed. The sensor cable can be routed through user-provided conduit back to the DuraTracker Flow Meter.
Regardless of the mounting method you select, always place the sensor over the center of the stream. After installation, and in the event that the sensor is submerged, a change in the accelerometer reading in the Cipher GO! software application for the flow meter may be used to detect if the sensor’s mounting position has changed. Changes in reported X- or Y-axis values may also indicate this.
Note
Do not pull on cable to remove the LevelRay, as you may damage the unit.

WARNING
This sensor has not been certified for use in “hazardous locations” as defined by the National Electric Code, by the Canadian Electrical Code, by the IEC, and by the ATEX directive.

2.4 Installation
2.4.1 Electrical Requirements
Carry out electrical connection by trained qualified personnel authorized by the plant operator. Only connect or disconnect in de-energized state.
2.4.2 Ambient Environment
Installation in all environments must fall within the temperature range of -20 to +60° C (-4 to 140 °F).
2.4.3 Radio Frequency Radiation
CAUTION
Install the sensor at least 20 cm from places where people may gather to minimize radio frequency radiation exposure.

2.5 Configuring the System with an ISCO Logger
Use the Cipher GO! or Flowlink application on a laptop computer to configure the Model 370 LevelRay radar level sensor with the DuraTracker. Connection to the DuraTracker to configure the system will be achieved by USB by Bluetooth pairing.

2.5.1 DuraTracker Setup
2.5.1.3 Flowlink
To configure the DuraTracker for operation with the LevelRay Sensor:
1. Select the TIENET tab and check if the attached sensor is listed in the Active TIENet Devices section.

a. If the device does not appear, select SCAN, then ADD the sensor once it appears in the Available TIENet Devices section. The Configure TIENet Measurements window then appears.
b. Choose parameters to add. The parameter names can be modified at this point as well. Check the box next to a parameter to configure it. Remove the parameter from those to be configured by deselecting its checkbox.

c. If the sensor is already listed in the Active TIENet Devices section, the Configure TIENet Measurements window can be opened by selecting CONFIGURE ACTIVE PARAMETERS.
2.5.1.4 Cipher GO!
To configure the DuraTracker for operation with the LevelRay Sensor using Cipher GO! software when it is connected to the DuraTracker:

1. Open Cipher GO! and navigate to the CONFIGURE tab.
2. Select TIENet Sensors and check if the attached sensor is listed under Available Sensors and shown with a gear symbol.
   
3. If not, select SCAN SENSORS and then ADD the sensor once it appears in the Available TIENet Devices list by selecting the ‘+’ sign to the left of the sensor’s name.
   Select the gear icon to configure the sensor. In the Configure TIENet device view you can  disable sensor parameters as needed.
4. Configure the Level settings as needed by expanding the 370 LEVEL tab. To make changes when entering values, either press ENTER or move to a different entry for the APPLY/UNDO selections to appear on the bottom. Selecting APPLY writes all settings currently altered on the page.

About Blanking Distance options
Min distance – The shortest distance from the radome (i.e., the highest expected liquid level). Because there is no dead band, this value can be so low as to have liquid touching the LevelRay housing radome. That is, it can be zero. And it should be zero if the LevelRay has a pressure sensor and you want it to continue to report level when submerged.
However, accuracy decreases within 150 mm range of sensor, so a minimum distance greater than 150 mm is recommended for best results. Depending on the elevation of your sensor, this value may be increased to help ensure that echoes read by the flow meter come only from the surface of the flow stream, and not off the walls or sides of the channel.

Note
Setting the minimum blanking distance to a value other than zero will stop the pressure sensor from providing level when submerged.
Max distance – The distance between the radome face and the bottom of the channel, or zero level. You can enter a slightly larger value than calculated (for example, 0.4–0.8″ (10–20 mm)) to make sure the sensor accurately reports the bottom of the channel.
2.5.1.5 Connecting and Authenticating

1. Start the Cipher GO! software. Select CONNECT TO DEVICE, then choose BLUETOOTH.
2. Choose the sensor from the list under Nearby Devices and select CONNECT.
3. Enter the Access Authentication Passkey (printed on the label next to the Bluetooth symbol) if this is the first time connecting to the device with the Cipher GO! database.The SITE tab is displayed when the passkey is accepted. This tab provides a way to change the site NAME and to list the device information and the current status.

Note
If Configuration Authentication is configured for the sensor, the Configuration Authentication Passkey must be entered before the setting of sensor configuration is allowed. The code is stored in memory in Cipher GO! and does not have to be entered again.The Configuration Authentication Passkey can be disabled by changing the Passkey to all zeroes (000000).
Once Configuration Authentication has been confirmed, all current configuration options become blue and selectable.2.5.1.6 Update Software
Updating the sensor’s software via Cipher GO! directly connected to the sensor is preferred. This takes approximately five minutes as opposed to approximately thirty minutes when done using the Update Software utility while connected to the DuraTracker.
Update Software selects the update file via File Explorer. By default, a 0370*.bin filter is set for selectable files. This filter can be altered to allow for all .bin files in the event the filename was changed.

START UPDATE begins the file transfer.

Once file transfer is complete, the sensor takes approximately 2 minutes to finish updating. The sensor disconnects to complete the update, then Cipher GO! notifies the user when the sensor is disconnected. Cipher GO! automatically attempts to reconnect to the sensor once it detects the sensor is available again.

2.6 Level Calibration

Although all other programming steps can be performed off-site, level must be set at the measurement site following installation.
Once the sensor is installed over the flow stream, measure the present liquid level (see figure at left) and enter this value for LEVEL, under ADJUST OPTIONS. Select ADJUST to perform the adjustment.
2.7 Firmware Updates
The TIENet device’s firmware is updated via the “Update Software” tool from Flowlink for the DuraTracker Flow Meter.
Step-by-step instructions for updating the firmware can be found in the Help text of the update application.
