Installation Instructions
THIS IS IMPORTANT INFORMATION.
READ IT CAREFULLY BEFORE BEGINNING WORK.
1) Inspect meter for damage that may have occurred during shipping.
Report any damage to the container to the freight carrier immediately.
2) Make sure your pressure, temperature, fluid and other requirements
are compatible with the meter.
3) Select a suitable location for installation to prevent excess stress on
the meter which may result from:
a) Misaligned pipe.
b) The weight of related plumbing.
c) “Water Hammer” which is most likely to occur when flow is
suddenly stopped as with quick closing solenoid operated
valves. (If necessary, a surge chamber should be installed. This
will also be useful in pressure start-up situations.)
d) Thermal expansion of liquid in a stagnated or valve isolated
system.
e) Instantaneous pressurization which will stress the meter and
could result in tube failure.
NOTE:
In closed thermal transfer or cooling systems, install the meter
in the cool side of the line to minimize meter expansion and contrac-
tion and possible fluid leaks at the threaded connections.
4) Handle the meter carefully during installation.
a) Use an appropriate amount of teflon tape on external pipe
threads before making connections. Do not use paste or stick
type thread sealing products.
b) Extreme caution should be exercised when using PVC solvent
cement around Acrylic. Acrylic cannot tolerate PVC solvent
cement and/or pipe dope. The fumes can cause crazing or
cracking of the acrylic. If flowmeters are to be installed in a glued
pipe configuration, install flowmeter after all glued fittings are
dried and lines are purged of all fumes.
c) Over tightening of plastic connections may result in fitting
damage.
5) Install the meter vertically with the inlet port at the bottom.
6) End fitting must be held secure when installing pipe. Failure to do
so can cause damage to the meter itself.
Revised note
7) Meters with plastic fittings must be installed so that fittings are not
made to support any part of the associated plumbing. In addition,
meter frame should be fastened to bulkhead, panel or column.
8) Meters used in gas service should have suitable valves plumbed in
at the inlet and outlet of the meter. These valves should be no more
than 1-1/2 pipe diameters from the meter ports. The valve at the
outlet should be used to create back pressure as required to prevent
float bounce. It should be set initially and then left alone. The inlet
valve should be used for throttling purposes. Depending on the
installation, valves may not be essential, but they are most useful in
many installations. Remember: To get a correct reading of flow in gas
service, it is necessary to know the pressure right at the outlet of the
meter (before the valve).
9) Pressure and temperature maximums must never be exceeded.
