Abstract

PURPOSE:To obtain bulk modulus readily and accurately, by obtaining the bulk modulus of liquid based on change in pressure in a liquid chamber when a plunger is inserted into an removed out of the liquid chamber filled with the liquid. CONSTITUTION:When the cam shaft of a calibration device 4 is rotated with a driving motor, a plunger 47 is moved up and down. Then the extending amount of a small diameter part 47a of the plunger into a fuel chamber 8 is periodically changed. As a result, the fuel pressure in the fuel chamber 8 is changed. At this time, the voltage difference between the high peak value and the low peak value of the output voltage of a piezoelectric pressure sensor 21 corresponds to the change (DELTAP) in fuel pressure due to the extending action of the small diameter part 47a of the plunger. Therefore, a bulk modulus K can be obtained by an expression K=(V/DELTAV).DELTAP by using the volume (V) of the fuel in the fuel chamber 8 and the volume change (DELTAV) of the fuel due to the movement of the small diameter part 47a of the plunger.
