Precautions for early use of natural gas flow meter products:

Commissioning of natural gas flow meter products

Whether it is a newly selected and designed or newly installed natural gas flow meter product measurement system; After our installation inspection and confirmation, the test run should be carried out.

During the trial operation of natural gas flow meter products, we must follow the following procedures:

1. First, close the on-off valve and regulating valve of the natural gas flow meter product; Then slowly open the bypass valve.

2. Finally, start the work of natural gas flow meter products.

Some problems will be encountered in starting the natural gas flow meter:

① For natural gas flow meter products with electrical remote integration, connect the power line and signal line first for preheating.

Our solution is: first slowly open the on-off valve in front of the natural gas flow meter product; Then slowly open the regulating valve behind the natural gas flow meter product; Finally, slowly close the bypass valve to make the natural gas flowmeter product work under normal flow.

② When the temperature of the measured fluid is very high, and the temperature difference from the ambient temperature is very large.

Our solution is to preheat the metering system at this time; Make the natural gas flow meter and pipeline system rise slowly, so as to ensure the normal operation of natural gas flowmeter products.

3. After that, we observe and record the change status of various operating parameters, such as temperature, pressure, etc.

If the system does not have too much vibration, noise and leakage; Moreover, after stable operation for a period of time, the trial operation is completed.

Normal operation of natural gas flow meter products

The natural gas flow meter can be put into normal operation after the test run is normal.

In the process of operation, the operator should do well in the following aspects for the use and maintenance of natural gas flow meter products:

1. Check and maintain the measuring system regularly.

The operator shall inspect the natural gas flow meter products, valves and pipeline systems.

The maintenance of equipment by operators mainly includes: A. protective equipment such as safety valve, flow limiting valve and alarm; b. Flow display instrument, recording device, compensation device and other flow auxiliary equipment; c. Filter, degasser and other supporting equipment.

2. Start up and shut down the natural gas flow meter must be carried out in the order of trial operation.

3. During normal operation, the operator shall always pay attention to the pressure, temperature, flow, viscosity and other parameters of the measured medium; See if these parameters meet the service range of the flow meter.
