Sewage flow meter type classification - focus on microfluidic control technology

Today's sewage flow meters on the market can be roughly classified into five categories based on the principle of metering:
Sewage flow meter
The first types of flowmeters include throttling flowmeters, bicombeflow flowmeters, constant velocity tube flowmeters, rotameters, and target flowmeters. These flowmeters use the principle of Bernoulli's equation to reflect the differential pressure signal of fluids. flow;
The second type of flowmeters are turbine flowmeters, vortex flowmeters, electromagnetic flowmeters, Doppler ultrasonic flowmeters, and hot wire flowmeters, which reflect the flow rate by measuring the fluid flow rate.
The third type of flowmeter has a gear type flowmeter, a scraper type flowmeter, and a rotary piston type flowmeter, which reflect the flow by measuring a small volume of one standard volume;
The fourth type of flow meter has a thermal mass flow meter, a differential pressure mass flow meter, an impeller mass flow meter, a Coriolis mass flow meter, and an indirect mass flow meter, which reflect the flow by measuring the fluid quality.
The fifth type of flowmeter has a gutter type flowmeter, which measures the flow by measuring the liquid level.
