Caution On PLC Connection
A circuit in some PLC may affect the flow measurement and the analog output may fluctuate.
In this case, make sure that the both PLC and the MTG flowmeter are properly grounded.
Proper grounding solves the fluctuation problem.
Cautions after installation
CAUTION
(1) Avoid using this instrument as a foothold after installation because such a use may cause
damage to equipment or humans.
(2) The integral type of this instrument uses glass for the converter window. It can break if
hit by a hand tool or other kind of utensil, and broken glass pieces may injure you. Pay
attention.
WARNING
(1) When removing this instrument, do removal work after ascertaining that there is no
residual liquid or pressure in the pipe or inside the detector. Otherwise, you may be
injured.

The output signal or indication may fluctuate depending on pulsation or other conditions
of the fluid. In such cases, increase the dumping time constant or take some other measure.

The analog output may fluctuate due to flow noise, which is generated by the process fluid
flow. In such a case, connect the upstream grounding ring to the downstream grounding
ring by a wire. The output fluctuation may be reduced.
