How to maintain a gas turbine flow meter

To ensure the gas turbine flowmeter operates normally for a long time, it is necessary to regularly check the operating status of the flowmeter and perform maintenance work to promptly eliminate any issues found.

1. Before putting the flowmeter into operation, the instrument's coefficient must be set first, and the wiring of the flowmeter must be carefully checked to ensure it is correct and well grounded before powering on.

2. Regularly clean, inspect, and recalibrate the flowmeter. For flowmeters with lubrication oil or cleaning liquid injection ports, lubricating oil or cleaning liquid should be injected regularly according to the manual's requirements to ensure the impeller operates well.

3,Monitor the display instrument's status, and if there are any abnormalities in the readings, check them promptly.

4. Keep the filter unobstructed. If the filter is clogged with impurities, it can be determined by the increase in the pressure gauge readings at its inlet and outlet, and any blockage should be removed promptly; otherwise, it will severely reduce the flow.

5. For large flow trade settlement measurement, to ensure the accuracy of the flowmeter, it must be calibrated regularly. On-site, online calibration equipment should be provided, or a portable calibration device should be equipped. Although the initial investment is relatively high, it is worthwhile considering long-term economic benefits.
