What are the commonly used liquid flow meters?
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.
An electromagnetic flowmeter 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.
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.
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. Orifice flow meter
Orifice flowmeter is an instrument that uses the throttling effect to measure liquid flow. An orifice plate is installed in the pipeline. When the liquid flows through the orifice plate, a certain
pressure difference will be generated. By measuring the pressure difference, the liquid flow rate can be calculated, and thus the flow rate can be obtained. The orifice flowmeter has the
characteristics of simple structure, easy installation, and low price, but it is easily affected by pipeline impurities and vibration.
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.
