2. ELECTROMAGNETIC FLOW METER INSPECTION

• 2.1 Step Instruction

  

• 2.1 Cleaning:<br>• Check for adhesion buildup inside the detector pipe, especially if using the meter with materials prone to sticking.<br>• Look for signs of decreased flow indication or other abnormalities.<br>• If buildup is found, clean the detector pipe with a soft brush and remove any unnecessary material.

  Problem

• 2.2 Calibration Verification (LF62*F Converter only):<br>• Use the built-in Mag-Prover calibrator to verify the original flow lab calibration without needing external tools.<br>• This can be used to check converter zero and span for maintenance or inspections. Mag-Prover Built-In Calibrator<br>• The converter LF62*F has a built-in reference signal calibration and verification circuit that allows you to re-verify the original magmeter flow lab calibration without the need for external devices.<br>• This reference signal can be used to check the zero and span of the converter for the purpose of instrumentation maintenance or periodical inspection. Refer to combined converter's manual.
