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.
Product disposal
The main body or parts of the converter for electromagnetic flowmeter l: LF62* 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.
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.
