What to Note When We Use Insertion Electromagnetic Flow Meters
Insertion electromagnetic flow meter is an instrument for measuring conductive liquids and works based on Faraday's law of electromagnetic induction. Thanks to its simple structure, light weight and easy installation, it is widely used to measure the volume flow of conductive liquids in closed pipelines.
For large pipe diameters, insertion electromagnetic flow meter is a preferred choice which can save costs and facilitate installation. Here are some aspects to note during use. 1. Ensure that the medium is full, which is the most basic requirement for mag flow meters and directly relates to the accuracy of the measurement result.
2. Be far away from interference. Due to its working principle, the electromagnetic flow meter is more sensitive to interference. When installing, select a location without interference.
3. The converter and the transmitter use the same phase power supply to avoid abnormal operation of the meter caused by the phase difference between the detection signal and the feedback signal, so the electromagnetic flow meter should be installed away from all electromagnetic fields and vibrations.
4. It is necessary to prevent the scale deposit on the inner wall of the transmitter conduit from affecting the measurement accuracy. At the same time, if the lining is destroyed or the transmitter is long working in places with strong acid, alkali and salt, short circuit will occur in the electrodes. Pay attention to protect it during use.
