3 Steps to Perform Commissioning of Electromagnetic Flow Meters

Aug 11 , 2023

Before the use of electromagnetic type flow meter, commissioning should be conducted to assure that it works fine as per it is designed. Then how to correctly perform commissioning? The following is the suggestion from professional engineers.

1. Inspection and preparation before commissioning

Before the commissioning of the electromagnetic flow meters, the pipeline and the instrument should be thoroughly inspected, including the cleaning of debris in the pipeline, and the drying of oil medium pipeline, the inspection of the electrical circuit, the grounding of the line, the inspection of insulation resistance and grounding resistance.

2.Water test

Whether it is an instrument for measuring water-based media, suspension liquids, or oil-based media, before formal commissioning, the condition of temperature, pressure, flow rate and others of the actual medium to be measured should be simulated for water test. If any abnormality occurs during the water test, or the parameters are missing, the instrument should be tested individually or recalibrated.

3. System commissioning

After the water test of electromagneticflow meter system, the system commissioning can be carried out. Pipes of oil medium need to be dried before system operation. The host system should perform code scanning on each measuring point in advance to ensure that all instrument components are in normal working condition before performing functional commissioning. During functional debugging, the host system reads the parameters of each instrument, tests the critical value alarm, etc., and then writes the control data. And then send the relevant data to the relevant host for analysis. After the commissioning in the system is completed, the host can perform PLC programming and commissioning of the instrument terminal unit.

After the commissioning is completed, 24-hour uninterrupted measurement should be carried out under continuous working conditions to observe the stability and reliability of the measurement data, in combination with other measurement methods until all the instruments of the system can operate according to the design requirements.
