Your device's appearance and connections may differ. Mounting All CODA KM-Series mass flow meters have mounting holes on the bottom for convenient attachment to flat panels. No straight runs of pipe are required upstream or downstream. These devices are position insensitive and can be mounted in any orientation. Note: Tare the meter after changing its position or orientation. LED Indicator The multicolor LED indicator light continuously displays green when power is supplied to the instrument. The LED light will also show red when transmitting or receiving through serial communication. 4 Getting Started LED Power Indicator Male DB-15 Connector USB Type C Tare Button / VCR® Inlet / VCR® Outlet Mounting Holes: 2× M5×0.8 10mm 0.207 1.024 0.914 1.731 CODA-Series Coriolis mass flow meter operating manual 5 Plumbing Process Ports Your CODA KM-Series Coriolis mass flow meter has been shipped with ¼ VCR®-compatible male process connections. Use in-line filters to prevent large particulates from entering the device. The suggested maximum particulate size is 20 microns for meters. ! Warning: Do not use pipe dopes or sealants on the process connections, as these compounds can cause permanent damage to the meter should they get into the flow stream. Maximum Pressure Each device includes a calibration sheet that lists its maximum operating pressure. The device specification sheet will also list the burst pressure. Operating above the burst pressure, even briefly, will result in the device rupturing. ! Warning: Devices exposed to pressures above the burst pressure listed in the device's specifications sheet, even for short periods, may leak or fail catastrophically, injuring persons or equipment. Connecting Plumbing Ensure that flow through your meter is in the same direction as the arrow on the flow body (usually left to right). 6 Getting Started Power and Signal Connections The USB-C connector on top of the device provides a serial interface to CODA KM-Series mass flow meters. Meters can be powered via the USB-C, DB-15, or M12 connector. The USB-C connector is not available on IP67rated devices. By default, CODA instruments have a male DB-15 connector. Note: The DB-15 and M12 pinouts for CODA differ from those of standard Alicat products 1 8 2 3 8 4 7 9 15 5 6 Male DB-15 on the device Male M12 on the device Pin Function 1 Not connected Function 05 Vdc output of mass flow rate Optional: 010 Vdc or 420 mA 2 Not connected 3 05 Vdc output of mass flow rate Optional: 010 Vdc or 420 mA 4 05 Vdc output of density Optional: 010 Vdc or 420 mA 5 Ground (analog signals) 6 Not connected 7 Not connected Power in Serial RS-232 RX Optional: RS-485 () Remote tare (ground to tare) Serial RS-232 TX Optional: RS-485 (+) Not connected Ground (common for power and digital communications) 8 Not connected Ground (analog signal) 9 Power in -- 10 Ground (common for power and digital communications) -- 11 Not connected -- 12 Remote tare (ground to tare) -- 13 Not connected -- 14 Serial RS-232 TX Optional: RS-485 (+) -- 15 Serial RS-232 RX Optional: RS-485 () -- CODA-Series Coriolis mass flow meter operating manual 7 Taring your Device Taring ensures accurate measurements by giving the device a zero reference. The taring process takes 10 seconds to complete once it begins. Prior to taring, flow fluid through the device and then stop flow to establish a no-flow condition while there is fluid present throughout the instrument. For best results, allow the electronics and the flow 15 minutes to reach a steady state temperature before taring. How to Tare There are three ways to communicate a tare command to a CODA KM-Series mass flow meter. Tare via Analog Every KM-Series meter has one pin that can be grounded to tare the device. Simply apply a good ground to this pin for at least 5 seconds to initiate the 10-second taring process (page 7). Tare via Serial CODA KM-Series meter can be tared by pushing the "Zero Device" button in Alicat's CODA View program (page 15). Once this button is pressed, the program will indicate that a tare is in progress. Do not start flow again until this process is complete. For taring via Modbus RTU serial protocol, please see Table 4 (page 14). Tare via Button While not recommended, the device can also be tared by pressing the tare button on the top of the device for 5 seconds to begin the 10-second taring process. ! Warning: Tare via the top button may result in an improper tare due to disturbance of the measurement tube caused by pressing the button. Note: Devices with IP67 rating will not have a tare button. When to Tare · After installing the meter in a different orientation. · After a significant impact to the flow meter. · After changing fluid. 8 Taring Communication Analog Communication KM-Series mass flow meters with a DB-15 connector include an analog output for both mass flow and density. CODA instruments with the optional 8-pin M12 connector have a single analog output for mass flow (page 7). Both of these outputs are linear across the entire range, provided the load impedance is within the nominal values specified in the table below. Analog Output Electrical Characteristics Outputs: Maximum Overrange Nominal Circuit Resistance Output Impedance DAC Update Rate DAC Resolution * Including sense resistor and wiring 05V +1V <500 1 k 50 Hz 14 bit 010V +2V <1k 1k 50 Hz 14 bit 420mA +4mA <500* -- 50 Hz 14 bit CODA-Series Coriolis mass flow meter operating manual 9 Analog I/O Data Ranges Analog inputs and outputs for your device were calibrated at the factory. By default, the full scale flow range maps 1:1 to the full scale voltage or current range of your device with a small overrange allowed. Custom analog ranges may also be set from the factory. Factory custom analog ranges will be listed on the calibration sheet. The full scale range for density on CODA devices is 02000 kg/m³. The CODA device is not sensitive enough to detect most gas densities, so it will always output a density reading of 99 kg/m³ or higher. Note: The density readings and accuracy are independent of mass flow readings and accuracy. ! Warning: Do not connect this device to "loop powered" systems, as this will destroy portions of the circuitry. If you must interface with existing loop powered systems, always use a signal isolator and a separate power supply. Serial Communication All CODA devices come with a digital serial interface, in addition to the analog interface. Modbus RTU is the default communications protocol for KM-Series meters. You can read and log sensor data and adjust device settings via these serial interfaces. Establishing Communication You can access the CODA serial interface through the USB port, 15-pin, or 8-pin connectors on top of the device. Consult the pinouts on page 7 for information on how to wire a connector for CODA. · If you have used a USB cable to connect your device to a computer running Windows 10, it should recognize your USB as a virtual COM port automatically. If not, please ensure your computer has the latest updates. · Once you have physically connected your device to a Windows PC, you can check which COM port number it is using by opening the Windows Device Manager and expanding "Ports (COM & LPT)". · The CODA device will be configured with the following settings: · Data Bits: 8 · Stop Bits: 1 · Parity: None · Flow Control: None · Modbus ID: 1 · The 15-Pin and 8-Pin connectors come pre-configured with a baud rate of 19.2 kbps. The USB-C serial interface will autodetect and accept any arbitrary rate from 9.6 kbps to 12 mbps. 10 Communication Multidrop Information CODA devices equipped with an RS-485 interface can operate on networks with other devices. The CODA RS-485 transceiver is a 1/2 unitload transceiver. When deploying CODA devices in an RS-485 network with multiple types of devices be sure to confirm that the total load of all devices does not exceed 32 unit loads on an unrepeated network segment. Consult the EIA-485 standard for more information. CODA KM-Series devices equipped with an RS-232 interface do not have a multidrop capable RS-232 transceiver. If a CODA device is plugged into an RS-232 network with other devices which have been adapted to support multidrop communication over RS-232 it will load the bus excessively and prevent other devices from communicating on that network. This includes other Alicat M-Series, L-Series, and P-Series devices. Modbus RTU Serial Protocol Alicat uses the Modbus standard in which registers are offset by 1 from addresses, meaning register 1 is equivalent to address 0, but some systems expect data to be mapped as 0-indexed addresses. Different Modbus control systems may refer to registers, offsets, or addresses in their documentation without clarifying their meaning. If your control system uses a 0-indexed numbering scheme then decrement all register references in this manual by 1. If you are unsure of which addressing scheme your control system uses, perform a test read of register 1200. If the CODA instrument responds with Error code 2: "Illegal Data Address", then your system is using the standard 1-indexed numbering system and the values in the manual can be used as-is. If the device returns a value of 0 instead of an error, decrement all registers listed in this section by 1 to arrive at the correct offset. CODA-Series Coriolis mass flow meter operating manual 11 Reading Process Data Alicat CODA KM-Series mass flow meters make no distinction between "Input" and "Holding" registers. Modbus function codes FC03 and FC04 can be used interchangeably to read data from the device. Sensor and process values are stored as big-endian, 32-bit IEEE-754 floating point numbers spanning two registers. Your control system will need to concatenate these into a single value to interpret them correctly. Alternate registers intended to simplify re-use of code written for non-CODA Alicat devices are included in parentheses. You can use either or both. Writing Control and Configuration Information All command and control requests to a CODA instrument are issued with Modbus function code FC16: "write multiple registers". For PID tuning assistance, please contact Alicat. Modbus Reading and Status Registers Note: All parameters in this table are read-access only.

Special commands consist of a Command ID and a Command Argument written in a single pass to these registers. Each command/argument pair is issued as a set of two 16-bit unsigned integers. Commands are started by a write to register 1000. If you send a command to register 1000 without sending an argument to 1001 the CODA instrument will interpret the command with a default argument of 0. At any time after sending a special command to registers 1000..1001 you can perform a read of the same registers to determine the success or failure of the last command. Register 1000 will store the last Command ID sent to the device, and register 1001 will return a status code indicating the command result. The Special Command Result Status Codes table below lists these codes.

CODA-Series Coriolis mass flow meter operating manual 15 Maintenance Cleaning This device requires minimal maintenance. If necessary, the outside of the device may be cleaned with a soft dry cloth. Avoid excess moisture or solvents. CODA KM-Series mass flow meters used with gas require no periodic cleaning, provided they have been flowing clean, dry gas. CODA KM-Series mass flow meters used with liquids require some precautions to avoid contamination and/or corrosion damage. Liquid should be filtered for particulates or biological materials that may grow in the device. When removing these units from the line for any extended period of time, make an effort to remove all of the liquid from the device, as deposits of calcium or other soluble minerals can affect the accuracy of the device. Recalibration CODA instruments are calibrated to NIST traceable standards at the time of manufacture. Due to the Coriolis technology, there is not a factory-recommended periodic recalibration cycle.
