Kaifeng Instrument LS Positive Displacement (Birotary) Flow Meter
Product Overviews
Structure & Principle
Features And Functions
● High accuracy, wide flow range( bigest of the PD flow meters), good repeatability;
● Rotation is stable, there is no pressure fluctuation with the fluid in the pipeline, the noise is low;
● The viscosity range of the measured medium is wide, it works better with high viscosity medium;
● The two rotors are not in need of the synchronous gear driving, the structure is simple and compact;
● The magnetic seal structure is reliable, the driving torque is strong;
● The flowmeter is provided with optoelectronic pulse transmitter which makes remote
measurement possible;
● The fluid state has little influence to the flowmeter, straight pipe is needed neither upstream nor downstream of the flowmeter.
