It can accurately measure in many environments, including varying temperatures, steam, dust, smoke, and foam. The radar's narrow beam can detect small targets and achieve precise positioning with high resolution. It has a maximum measuring range of 49.2 feet (15 m) and a minimum blind zone of 7.87 inches (0.2 m). All TRUE ECHO CR-L sensors can be field calibrated and programmed via the TRUE ECHO Bluetooth app. Automation Products Group, Inc. 1025 W 1700 N Logan, UT 84321 www.apgsensors.com | phone: 888-525-7300 | email: sales@apgsensors.com Doc # 9006836 Rev B Part # 201122 6 Dimensions 2 How To Read Your Label Each sensor comes with a label on the body with a full model number, a part number, and a serial number. The model number for the TRUE ECHO Radar Level Sensor will look something like this: SAMPLE: CR-L-GP-49-L1-P-E5-16-B0 The model number correlates with all the configurable options and tells you exactly what you have. Compare the model number to the options on the datasheet to identify your exact configuration. You can also call us with the model, part, or the serial number and we can help you.

Your sensor should be mounted away from inlets and outlets. · The radar path should be free from obstructions and as open as possible for the 4° off axis beam pattern. · Install the radar at least 7.9" (20 cm) away from side walls. · Wrap PTFE tape around threads before installing the radar. Do NOT over tighten. · Do not suspend by cable. 4 General Care Your TRUE ECHO Radar is very low maintenance and will need little care, as long as it is installed correctly. However, in general, you should: · Avoid applications for which the sensor was not designed, such as extreme temperatures, contact with incompatible corrosive chemicals, or other damaging environments. · Inspect the threads whenever you remove the sensor from duty or change its location. Ensure the radar is installed perpendicular to the measured surface. Ensure there are no interferences within the beam angle, such as walls, steps, ladders, river banks, etc. Install the radar at least 7.9" (20 cm) away from side walls. When installing in wells or pipes, place the radar as close to the center as possible to avoid interference from side walls. >7.9" (20cm) 5 FCC Information FCC regulations require 75-85 GHz radars to be installed to ensure a vertically downward orientation at fixed locations only. They must not operate while being moved or while inside a moving container. Hand-held applications are prohibited as well as marketing to When installing in tanks with domed lids, install off >7.9" residential consumers. center to avoid additional false echoes.

STEP 1: Ensure power is turned off. If the radar was installed in the hazardous location, ensure that the cables will not energize while the sensor is disconnected. STEP 2: Disconnect the radar wires. STEP 3: Remove the radar from its mount. STEP 4: Store it in a dry place, at a temperature between -40° to 158°F (-40° to 70°C). 10 Bluetooth App Use Bluetooth to connect wirelessly to your TRUE ECHO Radar, change radar parameters, and view the echo waveform graph. STEP 1: Install the TRUE ECHO app from the app store. STEP 2: Turn on your mobile device's Bluetooth. STEP 3: Open the TRUE ECHO app. On the Select Device screen, press "General Purpose Radar." STEP 4: Press the "Set up" button next to the radar's name. STEP 5: Press "Read" to view current settings in each tab. Press "Write" to save changes. 11 Programming Quick Start STEP 1: Validate the Media Type is set to liquid. The CR-L General Purpose Radar is typically used for liquid level applications. STEP 2: Choose a Vessel Type in the BASIC tab. This setting selects defaults to optimize performance. Vessel Parameter Depth Vessel Width Level change rate Application Damping time Big 10 m 3 m 0.1 m/min Used when stable 10s reading of a turbulent material is a priority. Small 1 to 10 m 1 to 3 m 1 m/min Suitable for most 5s working conditions. Fast 0.5 to 10 m 0.5 to 3 m 10 m/min Used when fast 3s measurement is needed. Test 0 to 15 m Unlimited Unlimited Best for in-house testing. 0s STEP 3: Press "Write" to confirm your choice. Press "Read" to view new settings. STEP 4: Set the Low Level, High Level, and Range settings. The High Level 20mA Sensor Zero Reference Point Range Distance Range setting should be equal to the Low Level setting to optimize performance. Level STEP 5: Press "Write" to confirm your choice. Press "Read" to view settings. Low Level 4mA STEP 6: Press the ECHO tab to view the echo waveform graph. This graph is used to determine echo strength and view any obstacles in the radar's path. The horizontal axis is distance from the sensor face; the vertical axis is the echo strength in decibels (dB). STEP 7: Close the waveform graph by pressing "Click Here To Close The Popup." STEP 8: In the case of obstructions, use the False Echo Begin and False Echo End settings in the ADVANCED tab to create a false echo mask. STEP 9: Press "Write" to confirm your choice. Press "Read" to view settings. STEP 10: Validate the performance of the radar in the ECHO tab.
