Product Introduction:
The JYSONIC ultrasonic flowmeter uses the Doppler effect of sound waves propagating in the fluid. By measuring the Doppler frequency shift of the sound waves scattered by moving particles in the fluid, the velocity of the fluid can be obtained. Combined with the built-in pressure water level gauge, the velocity area is used. Method, you can measure the flow of liquid. It is suitable for the flow measurement of open channels, rivers and difficult-to-build standard sections, as well as the flow measurement of various full and partial open channels.
Features:
●All functions are integrated into one design, meanwhile measure the average flow velocity, water depth, and water temperature
●Using velocity area method to measure flow, no head loss, no need to build standard weirs and troughs.
●Using the ultrasonic Doppler principle to measure the flow rate and flow rate, the measurement accuracy is high, and the initial speed is low.
●Without mechanical rotor structure, it has no influence on the water flow state, and the measurement is more accurate.
●Built-in temperature sensor, which can be used to compensate the influence of water temperature on the speed of sound.
●It can measure instantaneous flow and cumulative flow.
●Using frequency domain Doppler analysis algorithm, the data is stable and reliable, and the real-time performance is strong.
●Simple installation, no need for auxiliary engineering facilities
Applications:
●Flow measurement of various full and partial pipe scenarios in channels, rivers, sewers, drainage pipe networks, etc.
Measuring principle
The flow rate measurement of JYSONIC ultrasonic flowmeter is based on the Doppler effect. The probe emits a beam of ultrasonic waves obliquely upwards. The ultrasonic waves propagate in the fluid. The fluid will contain impurities such as bubbles or particles (it can be considered that the impurities in the fluid are consistent with the speed of the water flow). When ultrasonic waves come into contact with impurities in the fluid, the reflected ultrasonic waves will produce a Doppler frequency shift Δf, which is proportional to the flow velocity. The flow velocity of the fluid can be measured by measuring the Doppler frequency shift Δf.
