7.1 Maintenance
„ Cleaning
Adhesion might be created in the detector over a long period of time when used on certain
materials.
Try to confirm whether to cause the adhesion in the detector pipe when the phenomenon is seen, and and
an abnormality (ex. decreasing indication, etc.) is confirmed.
Please clean with a soft brush etc. and remove any unnecessary build up inside the meter. When using it in the
line to which such a phenomenon occurs easily, it is recommended that the detector pipe be cleaned regularly.
Use new gaskets when reinstalling the flowmeter detector in the pipeline.
„ Mag-Prover Built-In Calibrator
The converter LF60*F and LF61*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. 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.
„ Operative life
The design operative life of this flowmeter is 10 years from the date of shipment at a standard use condition .
The life of the flowmeter differs depending on the environmental conditions and the way it was used. To extend
the life of the flowmeter, inspect the flowmeter periodically and clean or replace components if necessary.
„ Product disposal
The electromagnetic flowmeter must be disposed of, according to the rules and regulations of your local
