Abstract

The invention provides a meter performance test system, which comprises an extraction device, at least one controllable valve, and a control cabinet; an inlet of the extraction device is connected with an oil tank and an outlet is connected with the oil tank through at least one meter, and the extraction device is used for extracting liquid stored in the oil tank and pressurizing the liquid to enable the liquid to flow through each meter and then be transmitted back to the oil tank; at least one controllable valve is arranged at the outlet of one meter; the control cabinet is connected with the extraction device and is used for controlling the extraction device to start to extract liquid according to an externally input starting signal and transmitting the extracted liquid to each meter; the control cabinet is also electrically connected with each controllable valve, and the control cabinet is used for changing the on-off state of each controllable valve according to a set time length, so that the repeated hydraulic impact of the liquid on each meter is realized, and each meter is tested.

Description

technical field [0001] The present application relates to the technical field of meter testing, in particular, to a meter performance testing system. Background technique [0002] The performance test of the meter in the fuel dispenser is generally performed by simulating the work of the fuel dispenser, that is, the motor and the pump continuously pass the liquid through the meter to test the performance of the meter. [0003] The current performance test plan is to deliver a stable liquid flow to the meter when performing a performance test on the meter, but the stable liquid flow cannot simulate the state of the meter in the actual refueling state. Therefore, the performance test of the stable liquid flow The solution has the problem of inaccurate performance testing of meters. Contents of the invention [0004] The purpose of the embodiments of the present application is to provide a meter performance testing system to solve the problem of inaccurate meter performance ...
