Azbil Corporation Instrument installation
Model MTG11A/18A, MTG11B/18B, MTG14C 2-3
(4) Slurry fluids containing solid matter (For example, pulp slurry, mud
slurry, cement slurry)
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
• The output signal or indication may fluctuate depending on pulsation or other
conditions of the fluid. In such cases, increase the damping 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.
m CAUTION
(1) After installation, do not use this instrument as a foothold or any others
improper purpose. Going so may result in damage to the instrument and/or
physical injury.
(2) The integral type of this instrument uses gland for the converter window.
Hitting the glass position of the indicator with a tool may break the glass and/or
cause physical injury.
m WARNING
(1) Before removing this unit, confirm that there is no residual liquid or pressure
inside the piping and the detector to avoid personal injury on damage to the
unit.
