Precautions on installation - Meter
•
When installing the meter outdoors, provide shade to prevent
exposure to direct sunlight
.
•
Do not mount the meter with its display surface facing
downwards.
•
Avoid installing the meter in a very high temperature
environment as this will shorten the battery life.
•
Provide clearance around the meter pipe section for piping
work. Provide clearance (30cm or more between pipe edge
and floor) for turning a box wrench, particularly under a
meter pipe section which has lower side bolts and nuts that
are difficult to tighten.
Installation
1. Insert the studding in the lower two bolts and fix the bolts to
the flanges.
2. Place the electromagnetic meter on the studs and set it in
the desired position, taking care not to subject it
3. Insert the remaining studs and slightly tighten all bolts. Make
sure that the meter pipe centre is not displaced and the
display is not askew. Fit the gaskets in between the pipe
ends and the meter..
4. After you check the displacement of the meter pipe centre,
tighten the nuts diagonally in the order shown by the arrows in
the figure above. Tighten the nuts to squeeze the gaskets until
fully sealed.
Caution
•
Make sure not to step on the display unit of the electromagnetic meter while you are
doing the pipework.
•
Never try to adjust the meter position using the display unit for grip after tightening the
bolts.
•
Do not attempt to correct problems by hitting the meter body.
