1. Before the vortex flowmeter is put into operation, it is necessary to set the meter coefficient first, check it carefully, and confirm that the flowmeter can be correctly connected and grounded before transmitting power.
2, keep the filter open. The filter is blocked by impurities, and can be judged from the increase in the reading of the pressure gauge at the entrance and exit of the filter, and the blockage is eliminated in time; otherwise, the flow rate will be seriously reduced.
3, for large-flow trade settlement measurement, in order to ensure the accuracy of the flowmeter, the flowmeter must always check. The site should be equipped with on-line calibration equipment, or equipped with a mobile calibration device. Although the one-time investment is relatively large, it is worthwhile considering the long-term economic benefits.
4. Vortex flowmeters need to be cleaned, checked and adjusted regularly. The flowmeter with lubricant or cleaning liquid injection port should be regularly injected with lubricating oil or cleaning fluid in order to maintain good impeller operation.
