IIEquipment principle

portable(Handheld) Doppler ultrasoundopen channelA flowmeter utilizes the Doppler effect of sound waves propagating in a fluid to measurecalmflow

bodyDoppler frequency shift of sound waves scattered by medium motion particlescomeObtain the velocity of the fluid, combined with the built-in pressure type water level gauge, and utilize the velocity surfaceamass

The law,It can measure the flow rate of the liquid. HMIwithinStorage spaceUp to 16MB, capable of storing over 100000 pieces of data, with built-in high-performance lithium batteries

Pool,oneThe second charge can work continuously for more than 12 hours, equipped with a LCD display screen that can display the flow rate in real timewater level、internet trafficWaiting for data.

Average flow velocity measurement：The measurement of flow velocity is achieved by emitting and receiving ultrasonic signals through an ultrasonic probe (transducer) and performing corresponding measurements

countObtained through computational processing:transducer1The transmission frequency isf1Ultrasonic signals are emitted from underwater at a certain angle towards the surface of the water, and upon contact

These large quantitiesThe average velocity of particles, also known as the average velocity of fluids.
