12VDC Ultrasonic Flow Meter With 0.03m/S-5.00m/S Flow Range Water Resistant
Ultrasonic flowmeter is an indispensable measuring instrument for measuring the flow of liquid, acid, and alkali. The accuracy of the set point-to-point related flowmeter is currently generally used in two ultrasonic flowmeters, Doppler ultrasonic flowmeter and time difference ultrasonic flowmeter. The Doppler type uses the phase difference method to measure the flow velocity. That is to say, because a sound wave of a known frequency moves in the fluid, the liquid itself has a moving speed, so the frequency or phase of the ultrasonic wave between the two receivers (or transmitters) will change relatively. The velocity of the liquid can be obtained by measuring this relative change. The time difference type uses the time difference method to measure the flow rate. That is to say, the propagation time of a sound wave of a certain speed between two receivers (or transmitters) due to the flow of the fluid changes, and the flow velocity of the fluid can be obtained by measuring this relative change. The correct installation method is very important to the flowmeter. Rui Lingyi shares installation tips and suggestions for ultrasonic flowmeters.

Integrated installation principle of ultrasonic level gauge
1.The distance from the emitting surface of the sensor to the
lowest liquid level should be less than the measuring range of the
selected instrument.
2.The distance from the emitting surface of the sensor to the
highest liquid level should be greater than the blind zone of the
selection and purchase of the instrument.
3.The emitting surface of the sensor should be parallel to the
liquid surface.
4.The installation position of the sensor should avoid the
fluctuation of the liquid level as much as possible, such as the
water inlet and outlet.
5.If the pool or tank wall is not smooth, the instrument should
keep the pool or tank wall above 0.3m.
6.If the distance from the transmitter surface of the sensor to the
highest liquid level is less than the blind zone of the selected
instrument, a telescopic tube should be installed, the diameter of
which is greater than 120 mm, the length is 0.35m ≤ 0.50m, the
vertical installation, the inner wall is smooth, and the inner hole
of the tank should be Greater than the inner diameter of the
extension tube. Or the pipe can be directly connected to the bottom
of the tank, the pipe diameter is greater than 80 mm, and the hole
at the bottom of the pipe can easily flow into liquid.
