Open channel ultrasonic flow meters for sewage and waste water treatment 600m3/h converter
Description
It has a proven track record of creating industry-leading innovations with unwavering product accuracy in the open-channel flow measurement world. Empowering you with true and timely flow data for your analysis, enable you to make critical wastewater flow decisions with absolute confidence.
General introduction
The Open channel Ultrasonic Flowmeter is a high precision flow measurement instrument, which use Transit Time Ultrasound principle to measure the flow in a variety of Flumes, Weirs or Troughs.

Dimensions
Features
- Built-in variety of algorithms, suitable for a variety of standard weirs.
- Stable sensors - Suitable for harsh industrial situations
- Isolated 4~20mA current output. Optional spot bus interface.
- The blind zone can be manually set, shielding the probe near the interference signal.
- Calibrated at Factory. And if required we shall do calibration at site.
Sensors
Ultrasonic sensor Static pressure sensor
Applications
Measurement of water flow in Effluent, Waste Water, Rivers, Canals, Drains, Sewage, etc.
Flow Totalizer parameters
Flow measuring range: Depends on the size of the flume.
Maximum Count: 9999999999
Types of suitable weirs: Triangular weir, rectangular weir, Parshall flume, etc.
Display accuracy: 1 count. Overall accuracy depends on the input signal. Different Weirs /
flumes has different accuracies. A triangular weir has 1 to 2% flow error, a rectangular weir
has 1 to 4% accuracy, a Parshall flume has 3% flow error, etc.
Display: 2.8-inch LCD. Displays Height, Flowrate, Total Flow, etc.
Output
Voltage output: DC 12V or 24V
Signal output: RS485/RS232; 4~20mA; 2 channel relay
Troughs
Triangle weirs
Installation sample
Advantage
The production capacity is 20000 ultrasonic converter and 100,000 ultrasonic sensor.
