River flowmeter, river section flowmeter, ultrasonic Doppler flowmeter,Variable area water flow meter
I. Overview
Acoustic Doppler Point Velocity Meter/Flowmeter, suitable for rivers, open channels, pipelines and other scenarios,
Online monitoring of water flow velocity, water level, temperature, instantaneous flow, cumulative flow.
The instrument uses the ultrasonic Doppler principle to measure the flow velocity, ultrasonic time difference method or static pressure method.
Measure the water level, and calculate the flow by setting the section. Doppler flowmeters are compact, non-rotating
It is widely used in sponge city,
Water supply/drainage network, black and odorous water bodies, natural rivers, open channels, reservoirs, flow fields for scientific research
Analysis, liquid level detection and other scenarios.
Second, the characteristics of the instrument
The sensor supports instantaneous flow and cumulative flow
Can measure the flow rate of still water
Can measure the flow of partial, full and open channels
Can measure the flow of circular, rectangular, trapezoidal and triangular sections
Wide flow velocity measurement range, 0 ~ 10m/s
High flow velocity measurement accuracy, 1mm/s error
Ultrasonic measurement of liquid level has high accuracy, with an error of 1mm (within 2m)
Pure physical method measurement, no calibration, no calibration
Support hydrostatic level measurement
Support temperature compensated flow rate measurement and liquid level measurement
Modbus RTU protocol
Sensor protection grade IP68, support long-term underwater work
