Title:
DISPLAY METHOD OF AMOUNT OF DISCHARGE OF TWO LIQUID
Document Type and Number:
Japanese Patent JPS56118113
Kind Code:
A
Abstract:
PURPOSE:To enable to keep the ratio of amount of discharge at a constant value and to make easy the display of amount of discharge of each liquid and the change in the ratio, by using a rotary pump and a reciprocating pump which are driven with the same driving source. CONSTITUTION:The liquid A is fed to a rotary pump 3 with a tank 1, and fed to a liquid mixer 9, while the liquid B is fed to a reciprocating pump 4 driven with the same motor 5 as the rotary pump 3 from a tank 2 and fed to the mixer 9. An electric signal proportional to the number of revolutions of the pump 3 is picked up at a pulse generator 13, and it is input to an F/I converter 15, to be inputted to a flow meter for liquid A as an electric signal SA. A variable resistor 19 provided at a stroke 18 of the reciprocating pump 4 shows a resistance value proportional to the amount of stroke. The electric signal SA is input to this variable resistor 19, the slider is connected to a V/I converter 23, and the output SB is input to a flow meter for liquid B 24.
