Applicable Working Conditions of Rotor Flowmeters

Rotor flowmeters, also known as impeller flowmeters, are typical velocity-type flow instruments that calculate fluid volume flow by detecting the rotational speed of an internal rotor driven by fluid kinetic energy. With simple principle, intuitive measurement, high cost performance and good repeatability, they are widely used in low-to-medium precision flow measurement for conventional industrial and civil fluid systems.

Firstly, rotor flowmeters are highly applicable to clean low-viscosity liquid working conditions. They can accurately measure water, coolant, light oil, and various low-viscosity solvent liquids. They are commonly deployed in water supply pipelines, mechanical cooling systems, and general fluid delivery lines for continuous flow monitoring.

Secondly, they adapt well to stable medium and low-pressure working conditions. The integral mechanical rotor structure features strong pressure resistance and stable operation under conventional pipeline pressure and room temperature to medium temperature environments. They are suitable for general industrial process monitoring with no extreme temperature and pressure impact.

In addition, rotor flowmeters are ideal for fixed flow rate and long-term continuous metering scenarios. With fast response and stable pulse signal output, they perform well in flow accumulation and statistical metering for stable fluid delivery, and are widely used in factory auxiliary pipelines and civil fluid metering systems.

Meanwhile, rotor flowmeters have clear usage limitations. They are not suitable for high-viscosity liquids, high-speed fluctuating flow, high-temperature and high-pressure harsh working conditions, or media containing solid impurities, which may cause rotor wear, jamming and measurement distortion.
