Product Overviews

Kaifeng Instrument LWG turbine flow sensors are used for measuring the volumetric flowrate and total volume of middle and low viscosity liquid (liquid or gas) in the closed pipe, and are widely applied in the industries such as petroleum, chemicals, scientific research, national defense and metering.

 

The sensor composes of turbine sensor and amplifier, the assembling structure of them is integrated type; the structure which is capable of measuring the forward and reverse flow is bidirectional type; the structure with insertion rod and can be installed in the big caliber pipe to measure the flowrate of liquid is plug-in type.
