Kaifeng Instrument LB Rotary Vane (Positive Displacement) Flow Meter
Product Overviews
Structure & Principle
Features And Functions
l High accuracy, wide flow range, good repeatability;
l Rotation is stable, there is no pressure fluctuation with the fluid in the pipeline, the noise is low;
l The accuracy is affected slightly by the viscosity change of the measured medium;
l The structure of the single case is simple, the body is compact and the weight is light; The structure of the dual case prevents the deformation of the measuring cavity caused by the high pressure and the change of the temperature to ensure the measuring accuracy, also the inside case assembly can be drawn out to carry out the maintenance and the pipe rinse, pipeline sweeping, pressure test.
l It is can be provided with various counters, senders in light of the requirement to realize the local display or remoteness;
l The measuring accuracy is independent of the fluid state, there needs no straight run of pipe in front and rear of the flowmeter, save of the land occupation and the cost.
Optional accessories
l Air eliminator
l Strainer
l Integrated air eliminator and strainer
