| 摘要 | PURPOSE:To detedt the change in strokes and periods immediately as a change in discharging flow rate without using any conversion table or the like by connecting the actuator of a variable flow rate type constant feed pump to a sensor for detecing stroke speeds. CONSTITUTION:In a system having a device 5 for changing setting for either one of strokes or periods of a constant feed pump of variable flow rate type and a displaying device for flow rate, the actuator 4 of the pump 1 is connected to a sensor 10 for detecting the stroke speed of the actuator. The detected stroke speed from the sensor 10 is inputted to an operator 12, and a flow rate is operated by the operator with respect to the prestored data on flow raes versus stroke speeds. The actual flow rate is displayed in a digital display device 15. Thus the change in periods and strokes is detected directly as a change in the discharge flow rate without using any conversion table or the like. | ||||||
