7.1 Maintenance

Cleaning
The adhesion might be caused in the detector pipe when using it for a long term when the fluid including the
electroconductive solid etc. is measured, and it causes the instruction decrease. Please confirm whether to
cause the adhesion in the detector pipe when the phenomenon of instruct decreasing while using it is seen, and
abnormality is not found even if it proofreading/confirms it.
Please clean with a soft brush etc. , and remove the adhesion thing. The instruction indicates a normal value by
removing the adhesion. When using it in the line to which such a phenomenon occurs easily, it is
recommended that the detector pipe be cleaned regularly ( at least once a year).
Use always new packing when mounting the flowmeter detector in the pipeline.
Calibration
The converter LF60*, LF61* and LF62* has a built-in reference signal generation circuit that generates dummy
flow rate signals. 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.
CAUTION
Do not touch the
GF630/LF600,LF610,LF620 and GF632
main body when high temperature fluid
is being measured.
The fluid raises the main body
temperature and can cause burns.
