Flowmeter Precautions

Flow meters try to avoid ferromagnetic objects and equipment with strong electromagnetic fields (such as large motors, large transformers, etc.), so as not to affect the magnetic field and flow signal of the sensor. Sensor scoop converter between the flow signal line and the excitation line. However, from the analysis of the damaged parts in the lightning failure, the induced high voltage and surge current causing the failure are mostly introduced from the power line of the control room, and the other two ways are less. Because electromagnetic flowmeters have more chances to measure suspended solids or dirty bodies than other flow meters, the probability of failure caused by the inner wall adhesion layer is relatively high. If the conductivity of the adhesive layer is similar to that of the liquid. Common debug period failures are usually caused by improper installation.
