Circulating water flow meter

Circulating water flow meterTypes includeElectromagnetic flowmeter, ultrasonic flowmeter, turbine flowmeter, vortex flowmeter, and volumetric flowmeterHere is a detailed introduction to these flow meters:

1. Electromagnetic flowmeter:

principleBased on Faraday's law of electromagnetic induction, the flow rate is calculated by measuring the electromotive force generated when a conductive liquid flows in a magnetic field.

advantageHigh measurement accuracy, up to ± 0.5% to ± 1.0%; Good stability, suitable for long-term continuous measurement; Strong anti-interference ability; Low water quality requirements, suitable for water with strong corrosiveness or impurities.

Applicable scenariosWidely used for flow measurement of various conductive liquids, including circulating water, sewage, etc.

2. Ultrasonic flowmeter：

principleCalculate flow rate by measuring the propagation time or velocity of ultrasonic waves in a fluid.

advantageNon contact measurement, not in contact with fluids, easy maintenance, long lifespan; Widely applicable, suitable for various liquids, including highly corrosive, sewage, cooling water and other fluids.

Applicable scenariosSuitable for all liquid flow measurements, especially for high-pressure, high-temperature, and highly corrosive liquid media.

3. Turbine flowmeter：

principleThe internal turbine is driven to rotate by water flow, and the speed is proportional to the flow rate.

advantageSimple structure, high precision, sensitive response, and moderate price.

Applicable scenariosSuitable for systems with relatively small and stable flow rates, widely used in water supply, drainage, cooling water and other fields, especially for clean water and low viscosity liquids.

4. Vortex flowmeter




principleWhen a fluid passes through an object, vortex streets are generated, and the frequency of the vortex streets is proportional to the flow velocity.

advantageNo movable parts, suitable for high flow, high temperature and high pressure situations, able to adapt to various liquids and gases.

Applicable scenariosSuitable for measuring various fluid flow rates, including circulating water, gas, steam, etc.









5. Volumetric flowmeter：




principleDetermine the flow rate by measuring the number of times a fixed volume of liquid passes through the measuring chamber.

advantageHigh precision and simple structure.

Applicable scenariosUsed for systems with flow requirements, suitable for low flow measurement.
