7.1 Maintenance
 Cleaning
 Adhesion might be created in the detectore 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 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 operative life of this flowmeter is 10 years from the date of shipment.
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
government.
Especially if you dispose of electrolytic capacitors to replace parts, have it done by an agency which is
licensed to handle industry waste materials.
 Check/Replacement of the display unit
When characters displayed on the LCD display become thin or blots come out, please adjust the setting of
LCD's display density. If the display is still not improved, the display unit comes to the end of its life. Please
replace the display unit with a new one. In order to use the display unit stably for a long time, it is preferable
to replace it early. For inspection and replacement, please contact your nearest Toshiba representative.
 Power supply unit (also used for excitation board)
Electronic components deteriorate faster when the ambient temperature is high. The life of the power
supply unit in the converter is 9 to 10 years if the ambient temperature is 40°C, and 5 to 6 years if it is
50° C. To extend the life of the flowmeter, we recommend you replace the power supply unit early.
Contact your nearest Toshiba representative for a flowmeter inspection or unit replacement.
