FLOW-3L Portable Doppler Flow MeterDetailed product description：

Characteristics of the LOW-3L portable Doppler flowmeter:

1. Can measure the flow rate of non full tubes (round tubes, egg shaped tubes, or other shaped tubes)
2. Can provide instantaneous and cumulative flow values
3. The instrument has built-in 130K data storage
4. Two communication interfaces to choose from: RS232 or SDI-12
5. Sensors can work for a long time in harsh environments and sewage quality
6. Optional SMS or GPRS wireless module for remote telemetry

6. CG20 measuring rod 3 sections
Measurement: Place the sensor (inclined part) in the direction of the upstream flow into the water level to complete automatic measurement
Operation interface: (Open the system and enter "My Devices" - "Residenflash2" - "Demo2" - "Demo2 icon" to enter the measurement)
Display flow rate, flow rate, and water level
The distance from the sensor to the bottom of the channel needs to be manually entered. If there is no input, the sensor will default to 0 in the channel
When measuring as a circular tube, click on the circle and enter the diameter as prompted, click on calculate area, click on calculate area, close and return to display real-time flow rate.
When measuring as a trapezoid, click on the trapezoid and enter the water surface width, slope angle, and data greater than 90 degrees; Click to calculate area, close and return to display real-time traffic.
When measuring as a rectangle, click on the rectangle to enter the width of the water surface, click on calculate area, close and return to display real-time flow rate.
Custom channel (requires purchase of ADCP accessories)
