Improper operation can lead to these failures in electromagnetic flow meters

Yokogawa electromagnetic flowmeter is an advanced flow measurement device that can accurately and stably measure the flow of various liquid media by utilizing the principle of electromagnetic induction. It is widely used in the field of industrial automation, providing reliable flow data for the production process and helping enterprises achieve efficient operations. However, there are some common malfunctions that may occur with Yokogawa electromagnetic flowmeters due to long-term use or improper operation. This article will introduce several common faults and their solutions.

1. Unstable readings: If the readings are unstable, it may be caused by a loose connection with the pipeline. The solution is to check the pipe connections, make sure they are tight, and seal them with sealing material.

2. Large reading deviation: If there is a large deviation between the reading and the actual flow rate, it may be due to sensor failure. The solution is to check whether the sensor is damaged or contaminated, clean the sensor surface or replace the sensor.

3. Unable to start: If it cannot be started, it may be due to power failure or internal circuit failure. The solution is to check whether the power connection is normal and ensure that the power supply is stable; if the power supply is normal, professional maintenance personnel may be required to perform maintenance or replace the instrument with a new one.

4. Display abnormality: If the display screen appears garbled, flickering or cannot be displayed, it may be due to a display failure or internal circuit failure. The solution is to check whether the display connection is normal and ensure that the connection is stable; if the display is still abnormal, it may be necessary to replace the display or have it repaired by professional maintenance personnel.

5. Leakage: If leakage occurs, it may be caused by insulation damage or poor grounding. The solution is to check the insulation condition to ensure that the insulation is intact; at the same time, check whether the grounding wire is well connected to ensure reliable grounding.

In short, we should investigate and solve the common faults of Yokogawa electromagnetic flowmeters in a timely manner. During operation, correct usage methods should be followed and regular maintenance and upkeep should be performed to ensure its normal operation and accurate flow measurement. If you encounter an unresolvable fault, it is recommended that professional instrument maintenance personnel perform inspection and maintenance to ensure the reliability and safety of the equipment.
