1. Before the turbine flowmeter is put into operation, the meter coefficients must be set and carefully checked to ensure that the flowmeter wiring is correct and the grounding is good before sending power.
2. Periodically clean, check and recalibrate the flowmeter. Flowmeters with lubricating oil or cleaning fluid injection ports should be regularly injected with lubricating oil or cleaning fluid in accordance with the requirements of the manual to maintain the impeller's good operation.
3. The monitoring shows the status of the instrument, and the reading of the instrument is evaluated and evaluated. If there is any abnormality, it should be checked in time.
4. Keep the filter unblocked. The filter is clogged with impurities. It can be judged from the increase in the difference between the pressure gauge readings at its inlet and outlet. If the clogging occurs, it is eliminated in time. Otherwise, the flow rate will be seriously reduced.
5. For large-flow trade settlement measurement, in order to ensure the accuracy of the flowmeter, the flowmeter must be calibrated frequently. The site should be equipped with online verification equipment, or with a removable verification device. Although the one-time investment is relatively large, it is worth considering the long-term economic benefits.
