Meter Installation
1� Remove the tape or the protective
plugs from the meter inlet and
outlet ports� The inlet port has
a 100 mesh stainless steel
conical strainer installed�
CAUTION
The mesh strainer must always be
installed when operating the meter;
otherwise, particles may enter the
meter chamber and disrupt the
smooth operation of the oval gears�
2� Wrap threaded male connections
with thread tape or use a pipe
sealant compound compatible with
petroleum fuels�
3� Install the meter on the pump us-
ing an appropriately sized nipple�
The bottom of the meter housing
is embossed with “INLET” and
“OUTLET” adjacent to its respec-
tive port to assist in correct
piping connections� For modular
applications with QM40, apply o-
rings and tighten 4 inlet and outlet
bolts with applicable outlet fitting.
See figure 4a, 4b, and 4c.
4� Install hose, nozzle, or filter onto
the system and tighten.
