Patent Primary Examiner
A liquid micrometer which includes: a liquid flow path which supplies liquid from a liquid supply device to a discharge nozzle; a flow rate sensor provided in the liquid flow path; a control valve provided in the liquid flow path between the liquid supply device and the flow rate sensor; a controller which controls the control valve such that a flow rate measured by the flow rate sensor becomes equal to a set value; a pressure sensor which measures pressure of the liquid injected from the discharge nozzle; and a calculating section which calculates the size of a work from the pressure measured by the pressure sensor in a state where the flow rate is maintained at the set value by the controller.
