Abstract
PURPOSE: To display the net weight value of "Flon" gas by subtracting the measured weight by the tare of a gas cylinder container by an automatic arithmetic circuit.
CONSTITUTION: With cock 5 of cylinder 4 opened, cooler 7 is filled with "Flon" gas through hose 6. The width detection output of a load cell is input to operational amplifier 10 being amplified by amplifier 8. Operational amplifier 10 eliminates the tare of a meter itself for zero adjustment and further performs subtraction by an output of tare setting digital switch 9 of cylinder 4. To its output side, voltage A equivalent to the net weight of the "Flon" gas in the cylinder is output and then displayed on digital voltmeter 14. The end of charging puts buzzer 20 into operation.
