PURPOSE:To transfer a liquid simply and surely at a desired and corrected flow quantity by applying a processing function, and a measuring function of the flow to a liquid transfer pump. CONSTITUTION:Pulses of different numbers per predetermined time are fed to a pulse motor 14 in sequence to transfer liquid in accordance with a program stored in a control section 17 beforehand, and the flow quantity of the transfer liquid at different number of pulses per predetermined time is measured by means of a mesuring section 11, a calibration curve is generated from the relatioship between the number of pulses and the measured data of the flow quantity of the transfer liquid and is stored in memory beforehand, and the number of pulses per predetermined time to be fed to the pulse motor 14 is determined from the desired flow quantity of the transfer liquid input from an input section by using the above calibration curve. Accordingly, an extremely correct flow quantity of the pump transfer liquid can be available, and also the operation is performed automatically under the control of a control section 17, thereby the handling of the pump can be simplfied. |
