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.
