Veinasa-SWS Doppler Flow Meter adopts Doppler effect, the relationship between the frequency difference of transmitting and receiving and the flow velocity, the relationship between the time difference of ultrasonic transmitting and receiving and the liquid level, the hydrostatic liquid level used for special working conditions, and the ambient temperature measurement was used to correct the actual ultrasonic propagation speed.
Other features of Veinasa-SWS Doppler Flow Meter:
1.Fast and accurate measurement, stable data output
2.Suitable for wide input voltage range, solar battery power supply, and flood period high flow rate environment.
1.Monitor the flow surface velocity of rivers
2.Open channels and underground sewage wells
3.Access to the water level gauge can be formed in the flow monitoring system.
Q: What's the main characteristics of this Ultrasonic Doppler Flowmeter?
A: Congratulations, it has compact structure and easy maintenance, factory price but amazing quality.
Q: What's the common power supply and signal output?
A: Common power supply and signal output is DC12V, RS485. But we can customize for you as demands.
Q: How can I collect data?
