Open Channel Ultrasonic Flow Meters Split Type For Waste Water Treatment ISO9001 / ISO14001

Open channel ultrasonic flow meter split type for waste water treatment 9000m3/h

Work principle

Its sensor is a transceiver which emits high frequency sound, which hits the medium surface and returns back to the sensor receiver. The time of travel of the ultrasound is inversely proportional to the height of the flowing medium. This way the height of the flowing medium is calculated. And with the algorithms programmed the Height, Flowrate and Total Flow are calculated and displayed.

Main technical index

Features

• Built-in variety of algorithms, suitable for a variety of standard weirs.
• Programmable Relay Output.
• Built in temperature sensor. Real-time automatic temperature compensation.
• 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

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.
