Ready stock
Product Description
Ultrasonic open channel flowmeter consists of ultrasonic probe for measuring liquid level and flow calculation transmitter. According to different structures, it can be divided into integrated and split types. It is suitable for measuring the flow of rectangular, trapezoidal and U-shaped open channels such as reservoirs, rivers, water conservancy projects, urban water supply, sewage treatment, farmland irrigation, water administration and water resources.

Flow range
0~93m3/h(And determine the range with weir tank specifications)

Weir trough type
Triangular weir, Rectangular weir, Full width weir, Parshall flume

Display accuracy
Depending on the input signal. The flow error related with weir trough:
Triangular weir :1~2%; Rectangular weir: 1~4%; Parshall flume: 3%

Display
2.8 inches LCD display, it can display height of liquid level, Instantaneous flow rate, cumulative flow, time flow, daily flow,
year flow, month flow, date, month and year, the battery level (Can be arbitrarily set)
