Introduction of Open channel ultrasonic flow meter

ULFM series provides accurate non-contact ultrasonic open channel flow measurement

 

Features  of Open channel ultrasonic flow meter

1.Open channel flow rate can be measure per 1mm according to the liqild level. The liquid level change 1mm.open channel flow rate changed with it. Measurement accurancy higher , flow measurement more accurante . 

2.Suitable for variety of flume:Parshall flume,Right-angled triangle weir,Rectangular weir.

3.Variety of flow rate unit is optional

4.Fully closed structure, Strong anti-corrosion

5.Strong anti-interference ability 

6.Low blind zone,High sensitivity,High stability

7.Provide at most 6 relay switch signal

8.MODBUS-RTU digital signal is avaliable.

9.The distance from transmitter to ultrasonic probe can up to 1000m

10.AC and DC power supply is optional. 

11.Romote control set up parameter is avaliable,Easy to operate.

Application

Ultrasonic Open Channel Flow meter is non-Contact instrument,Adopt Sound wave reflection principle to measuring liquid level in the water weir trough, Get the flow rate go thought the weir trough by conversion . The instrumeny mainly consist of ultrasonic probe and transmitter ,The materials in all plastic seal structure.can be widely application in Industry, environmental protection and ect industries.Measurement open channel flow rate accurately.
