Abstract

PURPOSE: To ensure a steady deciding at the point near the flowing speed of 0, by providing both the integrating function and the hysteresis property to the flowing deciding circuit.
CONSTITUTION: The output signal Vin of the electromagnetic flowmeter is supplied to the absolute value circuit Ab. The flowing direction deciding circuit J connects the signal obtained by giving a partial pressure to the output of the Miller integral network to the nonreverse input terminal. Thus the effect of noise and the deciding deflection at the point near the flowing speed 0 are eliminated to decide the flowing direction. And with this output of decision, the switches Q and Q' are turned on and off to obtain the absolute value of the output signal Vin. Then this value is divided by the DC signal proportional to the magnetic field generating current to obtain the flowing speed. This flowing speed obtained is then displayed.
