Accuracy Influence Factors and Calibration Methods of Impeller Flowmeters

Impeller flowmeters are essential velocity-based measuring devices widely used in industrial fluid metering due to their compact structure, fast response and cost-effective performance. Measurement accuracy is the core index to evaluate their working performance, which directly affects the precision of industrial production metering, material accounting and process control.
Working Principle and Basic Structural Composition of Impeller Flowmeters

Impeller flowmeters are one of the most widely used velocity-type flow measuring instruments in industrial fluid measurement. With the advantages of high measurement accuracy, stable operation, simple structure and low cost, they are extensively applied in the measurement of liquid and gas flow in petroleum, chemical industry, water supply, food processing and other fields.
Explosion-proof pressure transmitter

Explosion-proof pressure transmitters are specialized industrial sensing instruments designed for flammable and explosive working environments, serving as core components of industrial process automation and safety monitoring systems. Different from ordinary pressure transmitters, they integrate high-precision pressure sensing technology and professional explosion-proof structural design, which can effectively avoid ignition risks caused by electrical sparks, high-temperature surfaces and circuit faults in explosive gas atmospheres.
