What types of liquid flow meters are there?


Liquid flowmeter is an instrument used to measure liquid flow. It is often used in various industrial fields. Currently, the commonly used 

ones include vortex flowmeter, electromagnetic flow meter,oval gear flow meter, ultrasonic flow meter,and orifice flow meter,

mass flow meter, etc.



1. Electromagnetic flowmeter


An electromagnetic flow meter is an instrument that uses the principle of electromagnetic induction to measure liquid flow. A measuring 

electrode is installed in the pipeline. When the liquid flows through the electrode, a certain induced potential will be generated. By measuring

 the induced potential, the liquid flow rate can be calculated, and then the flow rate can be obtained. Electromagnetic flowmeter has the 

characteristics of high measurement accuracy, wide measurement range, good stability and fast response speed.



2 Vortex flowmeter


Vortex flowmeter is a commonly used liquid flowmeter. Its working principle is based on the vortex principle. A probe is installed in the 

pipeline. When the liquid flows through the probe, a vortex street is formed downstream of the probe, resulting in a certain pressure 

difference. By measuring the pressure difference, the liquid flow rate can be calculated, and thus the flow rate can be obtained. 

Vortex flow meters have the characteristics of high measurement accuracy, good stability, fast response speed, and long service life.



3.Oval gear flowmeter


It is a flow meter professionally used to measure micro-precision flow meters. It is widely used in laboratory scientific research institutions,

 chemical plant workshops, flow quantitative proportioning, and precise flow output.


4. Ultrasonic flow meter


Ultrasonic flow meter is an instrument that uses ultrasonic waves to measure liquid flow. A pair of ultrasonic probes are installed in the 

pipeline, one probe emits ultrasonic waves and the other probe receives ultrasonic waves. When the liquid flows, the propagation speed 

of the ultrasonic wave will change. By measuring the change, the liquid flow rate can be calculated, and then the flow rate can be obtained. 

Ultrasonic flow meters have the characteristics of non-contact measurement, high measurement accuracy, wide measurement range, and 

good stability.



5. Mass flow meter


A mass flow meter is an instrument that directly measures the mass flow of a liquid. Install a mass flow sensor in the pipe to calculate the 

flow rate by measuring the mass of the liquid. Mass flow meters have the characteristics of high measurement accuracy, good stability, fast 

response speed, and long service life, but they are relatively expensive.


6.Liquid Turbine Flow Meter
