5) after, circuit board (83) to be controlled receives vibrating sensor (31) and light receiver (62) signal, control circuit board
(83) control gas trap (26) is closed so that air inlet pipe (22) stopping pours into gas, observation pressure gauge (25) registration, to be held
The maximum pressure-bearing value of device pressure；
6) air inlet pipe (22), are connected to external environment, air pressure in test chamber is made to become normal atmospheric value, subsequent start-up gear again
It pumps (72), water is re-injected in cylinder (1), after filling, is pulled water out, control circuit board (83) is according to flowmeter (74)
The secondary volumetric values of water flow value calculating water；Control circuit board (83) is by comparing a volumetric values and secondary volumetric values, to reach
The effect of detection container volume.
