<p>An actual discharge from a reciprocating pump is calculated precisely. A flow volume calculation unit (10) obtains the instantaneous flow volume of a fluid (W) by a pulse signal outputted from a flow volume sensor (23) provided on a transfer channel (24) for transferring the fluid (W), and obtains operation timing of each reciprocating operation by a reciprocating pump (21) by at least one out of a pump synchronous pulse signal outputted from the reciprocating pump (21) on the transfer channel (24), a pressure waveform signal outputted from a pressure sensor (22) on the transfer channel (24), a flow volume waveform signal outputted from the flow volume sensor (23) and timing information of each unit time set in advance. Then, the flow volume calculation unit (10) calculates the flow volume display value of the fluid (W) according to the instantaneous flow volume and the operation timing and displays the flow volume display value on a display panel (13).</p> |
