Check out 8 main reasons for errors when using magnetic flow meter for water treatment, magnetic flow meter for chemical process, or beverage industry electromagnetic flowmeter hygienic:

Magnetic field interference:

Electromagnetic flow meters are very sensitive to magnetic fields, and external magnetic field interference, such as large motors or transformers nearby, may affect the measurement results.

Temperature changes:

Temperature changes affect the conductivity of the liquid, which in turn affects the measurement accuracy of the electromagnetic flow meter.

Uneven flow velocity distribution:

In the pipeline upstream of the flow meter, if the flow velocity distribution is uneven, it may cause measurement errors.

Improper installation position:

The installation position of the flow meter does not meet the requirements, such as insufficient length of the upstream straight pipe section, or elbows, valves and other components that affect the flow of the fluid, which may cause measurement errors

Electrical component failure:

Failure of the converter or signal transmission line of the electromagnetic flow meter will also cause inaccurate measurement data.

Electrode contamination or deposition:

Solid particles or chemicals in the liquid may accumulate on the electrode, changing the effective area of the electrode, thereby affecting the measurement accuracy.

Electrode corrosion:

When measuring certain corrosive liquids, the electrode material may be corroded, causing the electrode surface state to change and affecting the measurement results.

Electrode insulation problem:

If the electrode insulation is poor, leakage will occur in the measurement circuit, causing measurement errors.

In order to reduce these errors, the electromagnetic flow meter needs to be calibrated and maintained regularly to ensure its normal operation. At the same time, during the installation and use process, the operating procedures should be strictly followed to avoid the occurrence of the above problems. Pokcenser Automation will assist you to troubleshooting and solve those!
