principle
When an ultrasonic beam propagates in a liquid, the flow of the liquid will cause a slight change in propagation time, and the change in propagation time is proportional to the flow velocity of the liquid, which follows the following expression:
among which 
θThe angle between the sound beam and the direction of liquid flow
MThe number of straight line propagation times of sound beam in liquid
DFor the inner diameter of the pipeline
TUPThe propagation time of the sound beam in the positive direction
TdownThe propagation time of the sound beam in the opposite direction
△ T=Tup-Tdown
special point
●DN50Dual channel high-precision design with diversion layer above caliber
●Protection levelIP68
●Built in quantitative controller and time-sharing accumulator
Automatically start the controller at the set time to achieve automatic timed and quantitative water supply or irrigation.
Gradual rate has been achieved by accumulating traffic in a set time period.
●Thermal measurement
Optional dual channelPT1000Temperature measurement function, capable of heat measurement, suitable for the air conditioning and refrigeration industry.
●Ultrasonic measurement, no rotation, no worn parts
Long term guarantee of measurement accuracy and high overall reliability.
Suitable for various water qualities, including those containing gravel and weeds.
