1. Ensure that the fluid does not experience rapid pulse fluctuations
2. Ensure that there is no reverse surge pressure
3. The minimum/maximum flow rate should be within the linear range of the flowmeter
4. The system should be cleaned after appropriate time intervals
5. Avoid voltage and current surges
The connection terminals must not be connected incorrectly, otherwise the flow meter may be damaged
