Electromagnetic flowmeter is a flowmeter that applies Faraday's law of electromagnetic induction and is used to measure the volume flow of conductive liquids and slurries in closed pipes.
Electromagnetic flowmeter is a flowmeter that applies Faraday's law of electromagnetic induction and is used to measure the volume flow of conductive liquids and slurries in closed pipes. It consists of two parts: electromagnetic flow sensor and electromagnetic flow converter.
The working principle of electromagnetic flowmeter is Faraday’s law of electromagnetic induction. This law states that when a conducting liquid passes through a magnetic field, a voltage is induced across the conductor. The magnitude of the voltage is directly proportional to the conductor's speed, length, and magnetic field strength.
Precautions for use:
1. Accuracy level and functions Select the accuracy level of the instrument according to the measurement requirements and usage occasions to achieve economical results. When used for process control, different accuracy levels can be selected according to the control requirements; some are just for detecting process flow and do not require precise control and measurement, so you can choose a slightly lower accuracy level.
2. Measuring medium flow rate, instrument range and diameter. When measuring general media, the full scale flow rate of the electromagnetic flowmeter can be selected within the range of 0.5-12m/s for measuring the medium flow, which is relatively wide. The instrument specification (diameter) selected is not necessarily the same as the process pipeline. It should be determined based on whether the measured flow range is within the flow rate range. That is, when the pipeline flow rate is low and cannot meet the requirements of the flow meter or the measurement accuracy cannot be guaranteed at this flow rate, It is necessary to reduce the diameter of the instrument to increase the flow rate in the pipe and obtain 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. It should be installed in a dry and ventilated place as far as possible, away from the sun and rain. The ambient temperature should be between -20 and +60°C, and the relative humidity should be less than 85%.
