Process Control Devices manufacture various digital flow meter used in industry as per fluid property. Turbine flow meter is used for measuring the instant flow rate of clean liquid as well as gas. It consists of turbine rotor mechanism, pickup coil, and an electronics module. the velocity of flow is directly proportional to the flow rate. Media it can measure is water, oil, diesel, solvent, chemical and any clear liquid. viscosity should be less than 20 CP.
