2. When measuring the medium flow rate, meter range and caliber measurement of the general medium, the full flow of the electromagnetic flowmeter can be selected within the range of 0.5-12 m/s of the measured medium flow rate, and the range is relatively wide. The instrument specification (caliber) is not necessarily the same as the process pipe. It should be determined according to whether the measured flow range is within the flow rate range. That is, when the pipe flow rate is too low to meet the flow meter requirements or the measurement accuracy cannot be guaranteed at this flow rate, It is necessary to reduce the gauge diameter, thereby increasing the flow rate inside the tube and obtaining satisfactory measurement results. 3. Try to avoid ferromagnetic objects and equipment with strong electromagnetic fields to prevent the magnetic field from affecting the working magnetic field and flow signal of the sensor. 4, should be installed in the dry and ventilated place, to avoid sun and rain, the ambient temperature should be -20 ~ +60 ° C, relative humidity is less than 85%. 5, there should be ample space around the flowmeter for easy testing and maintenance.

Precautions for the use of electromagnetic flowmeter
1. Accuracy class and function According to the measurement requirements and the use occasions, the instrument accuracy level is selected to achieve economical cost. For the case of process control, different accuracy levels are selected according to the control requirements; some are only for detecting the process flow, and there is no need to do precise control and measurement, and the accuracy level can be selected to be slightly lower.
