[0002] When conducting diaphragm experiments, the difficult part is dealing with the test fuel. After the fuel is filtered by the diaphragm, it enters a sample receiving container such as a bucket through a funnel. During this process, the fuel is exposed to the outside and may leak onto the ground, resulting in a messy sampling site. However, with a hose equipped on the instrument monitor, this problem is solved. Both the flushing fuel and the test fuel can return to the fuel system through the hose and will never be exposed to air, rain, or other pollution sources. There is no need to use buckets or funnels, and fuel leakage will not occur.

[0003] For the above reasons, there is a need for an instrument monitor for diaphragm closed-loop testing, which can return both the flushing fuel and the test fuel to the fuel system through a hose, and will never be exposed to air, rain, or other pollution sources. There is no need to use fuel receiving devices such as buckets and funnels, and fuel leakage will not occur. Furthermore, it can improve the cleanliness of the on-site environment and avoid the situation where the fuel is affected by external dirt and affects the test results. Summary of the Utility Model

[0022] Open the valve between the sampling quick-connect joint and the main pipeline before the selection valve, adjust the selection valve to the "Flush" position, and flush the pipeline with at least 2L of fuel.

[0023] Adjust the selection valve to the "TEST" position so that 5L of fuel passes through the on-site sampling test device and is discharged into the sample receiver.

[0024] Close the valve between the sampling quick connector and the main pipeline, adjust the selection valve to the "STOP" position and disassemble the test device, etc.

[0025] Then operate according to the following steps:

[0026] 1. Install a return connection at the inlet of the system pump;

[0027] 2. Insert a plastic monitor into the sampler housing;

[0028] 3. Install an instrument monitor between the sampler assembly and the grounding hose;

[0029] 4. Turn the sampler valve to the stop position;

[0032] 7. Turn the sampler valve to the flushing position and flush the pipeline with a certain volume of fuel first;

[0033] 8. Turn the sampler valve to the test position. Then, when the instrument monitor shows that after testing with 5L of fuel, close the valve. Disconnect the return connection and then disconnect the sampling connection.

[0034] It is realized that both the flushing fuel and the test fuel can return to the fuel system through the hose, and will never be exposed to air, rain or other pollution sources. There is no need to use fuel receiving devices such as buckets and funnels, and there will be no fuel leakage, thus improving the cleanliness of the on-site environment and avoiding the situation that the fuel is affected by external dirt and affects the test effect.
