Open Channel Flow Meter
1. Product display:
2. Ultrasonic liquid level principle
The ultrasonic transducer emits an ultrasonic pulse of the krypton, which propagates to the measured liquid surface by transferring the coal, and then returns to the receiving transducer through the sound transmitting medium after being reflected. Measure the time when the ultrasonic pulse propagates from the transmission to the reception in the sound transmission medium, and then according to the sound edge in the sound transmission medium, the distance from the energy conversion to the liquid surface can be calculated to determine the liquid level.
3.The flow measurement principle of the water gutter
The higher the flow rate in a smooth open channel, the higher the liquid level; the smaller the flow rate, the lower the liquid level. The helium flow can be estimated by measuring the water level. Correspondence between flow and water level in a common open channel, subject to the slope of the channel
Ratio and surface roughness. The installation of the water gutter in the channel produces a throttling effect, so that the flow in the open channel has a fixed correspondence with the liquid level.
Commonly used water measuring tanks are: Bachel tank, triangular crucible, rectangular crucible, etc., preferably Bachel tank.
