INTELLIGENT TURBINE FLOWMETER

16 bits microprocessor -MSP430 7 points linear correction of K-factor Flowrate/Total flow quantity display 1.     FEATURES

     Intelligent turbine flowmeter & Intelligent turbine flow transducer adopts MSP430 from TI Co. USA for microprocessor. Using hard alloy bearing in turbine sensor, the flowmeter can be widely applied in measurement of water, gasoline or various low viscosity fluids. Intelligent turbine flowmeter displays flowrate and total quantity on the LCD simultaneously. 4-20mA standard current signals are output by the intelligent turbine flow transducer, which can be connected to PLC or DCS computer and so on. The intelligent turbine flowmeter provides the function of correction of non-linear instrument coefficient in order to achieve higher accuracy, if necessary.
