Installation and maintenance
1. Before the flowmeter is installed in the process pipeline, the process pipeline should be purged or cleaned to prevent impurities in the pipeline from blocking the meter and affecting the normal operation.
2. The flowmeter should be installed vertically with the medium flowing upward. The angle between the centerline of the flowmeter and the plumb line should not exceed 5 °.
3. To prevent the pipeline from being deformed under pressure, the flowmeter interface must be centered and parallel to the pipeline axis. If necessary, properly support the pipeline on both sides of the flowmeter to prevent vibration and reduce the axial pressure of the flowmeter.
4. If the medium contains solid impurities, a filter should be installed upstream of the flow meter.
5. In order to facilitate maintenance and cleaning, it is recommended to install a bypass line.
6. To ensure the flow indication is stable, it is recommended to install a flow regulating valve downstream of the flow meter.
7. When measuring liquid, the working pressure should be not less than 2 times the maximum pressure loss; when measuring the gas, the working pressure should be not less than 5 times the maximum pressure loss to make the flowmeter work stably.
8. This instrument works based on the principle of magnetic coupling. It should be ensured that the magnetic field generated by other equipment around the instrument does not affect the measurement results.
