1. Caliber

Generally, the caliber of the electromagnetic flowmeter should be consistent with the measured pipeline.

2. Lining and electrodes

The lining and electrodes of the electromagnetic flowmeter must be selected according to the chemical and physical properties of the measured medium (for example, when the medium flows, the temperature and pressure inside the pipeline must be lower than the temperature and pressure that the lining can bear). If the electrode and lining are not properly selected, the electromagnetic flowmeter will be damaged, even the lining will leak, and the flowmeter will not be able to measure the flow.
