In order to ensure the long-term normal operation of the gas turbine flowmeter, it is necessary to check the operation status of the flowmeter frequently, perform maintenance work, and find out problems in time.

1. Before the turbine flowmeter is put into operation, the meter factor should be set first. Check carefully to make sure that the flowmeter is connected correctly and the grounding is good before sending power.

2. Regularly clean, inspect and re-calibrate the flowmeter. The flowmeter with lubricating oil or cleaning fluid injection port should be filled with lubricating oil or cleaning fluid regularly according to the requirements of the manual to maintain good operation of the impeller.

3. The inspection shows the status of the instrument, and the evaluation shows the reading of the meter. If there is an abnormality, it should be checked in time.

4. For large-flow trade settlement measurement, in order to ensure the accuracy of the flowmeter, the flowmeter must be checked frequently. The site should be equipped with on-line calibration equipment or equipped with a mobile calibration device. Although the one-time investment is large, it is worth considering from the long-term economic benefits.

5. Keep the filter unblocked. The filter is blocked by impurities, and it can be judged from the increase of the difference of the pressure gauge reading at the inlet and the outlet, and the blockage is promptly eliminated, otherwise the flow will be seriously reduced.
