Magnetic Flowmeter Use And Maintenance

When using electromagnetic flowmeter, first of all, make sure that the installation location is reasonable, to avoid the influence of strong magnetic field, vibration or temperature change. At the same time, to ensure that the pipeline is filled with the measured liquid, to avoid the mixing of gas or air bubbles to ensure measurement accuracy. In addition, before use, you also need to carefully check whether the meter display is normal, whether the range setting is reasonable, whether the zero point is accurate, etc., to ensure the accuracy of the measurement.

In the process of use, we have to follow the operation specification to avoid the operation error resulting in inaccurate measurement or damage to the instrument. For example, before starting, make sure the power supply is stable and check whether the pipeline is filled with liquid; when shutting down, the power supply should be turned off first and then the valve should be closed. In addition, it is also necessary to pay attention to the measuring range of the flowmeter to avoid exceeding its measuring range resulting in inaccurate measurement.

However, correct use alone does not guarantee long-term stable operation of electromagnetic flow meters. Therefore, careful maintenance measures are equally important. First of all, the electromagnetic flowmeter should be cleaned regularly to remove the accumulated scale or deposits on the inner wall of the measuring tube to ensure the measurement accuracy. In the cleaning process, a soft cloth or brush should be used to gently wipe, avoid the use of chemical cleaners, so as not to cause damage to the instrument.

Secondly, the sensor and cable connections of the electromagnetic flowmeter should be checked regularly to ensure that the connections are good and there is no breakage or aging. If abnormalities are found, they should be replaced or repaired in a timely manner so as not to affect the measurement accuracy and normal operation of the meter.

In addition, electromagnetic flowmeters need to be regularly calibrated and calibrated. By using a standard flowmeter or calibration device, the coefficients or parameters of the electromagnetic flowmeter can be adjusted to ensure the accuracy of the measurement results. Calibration and calibration work should be carried out by professional technicians or manufacturers of after-sales personnel to ensure that the operation is correct and effective.

In short, the use and maintenance of electromagnetic flowmeter is a process that requires care and patience. Only the correct use and careful maintenance can ensure that the electromagnetic flowmeter can be long-term stable operation, accurate measurement, for industrial automation measurement to provide reliable data support.
