AI Technical Summary
The existing metering tanks used for fuel dispenser calibration have a slow drainage speed and require the tanks to be placed at a high position for drainage, which affects the efficiency and convenience of the calibration operation.
An inlet solenoid valve is installed at the top of the inlet pipe, and a drain solenoid valve is installed at the top of the drain pipe. They are connected to a high-pressure gas tank through a connecting pipe. High-pressure gas is used to push the liquid to accelerate the draining process. At the same time, an extension hose is connected to the output end of the drain pipe to ensure that the liquid can be discharged quickly at a low point.
It improves the efficiency of the verification process, saves manpower, enhances the convenience of the draining operation, and ensures the speed and thoroughness of the draining.
