INSTALLATION
THIS UNIT SHOULD BE INSTALLED AND SERVICED BY TECHNICALLY QUALIFIED
PERSONNEL TRAINED IN MAINTAINING INDUSTRIAL CLASS FLOW INSTRUMENTATION
AND PROCESSING EQUIPMENT.
READ INSTRUCTIONS THOROUGHLY BEFORE INSTALLING THE UNIT. IF YOU HAVE ANY
QUESTIONS REGARDING PRODUCT INSTALLATION OR MAINTENANCE, CALL YOUR
LOCAL SUPPLIER FOR MORE INFORMATION.
LIQUID PIPE SEALANTS, PVC/CPVC PRIMERS AND PVC/CPVC CEMENTS CONTAIN
SOLVENTS THAT ARE NOT COMPATIBLE WITH POLYSULFONE PLASTIC. ALLOWING
LIQUID PIPE SEALANTS TO CONTACT THE PLASTIC FLOW METER WILL RESULT IN
WEAKENING OF THE FLOW METER BODY AND POTENTIALLY CAUSE FRACTURING
UNDER PRESSURE.
Precautions
• Do not allow liquid pipe sealant, PVC/CPVC primer or PVC/CPVC cements to come into
contact with the plastic flow meter� These contain solvents that are not compatible with
the flow meter body and may result in weakening and potentially fracturing of the unit
while under pressure� If a pipe sealant is required, use Teflon® tape�
• Do not install the flow meter in piping systems that are not aligned or properly
supported�
• Do not connect the flow meter male plastic NPT fittings to female metal NPT couplings�
Differences in coefficients of expansion between metals and plastics can cause the
plastic flow meter body to crack� Use a female-to-female plastic pipe coupling to
connect metal pipe to the plastic flow meter�
• Do not use pipe wrenches on the flow meter body� Use an open-end wrench on the
integral hex flats during installation to avoid scarring or otherwise damaging the
external surface�
• Do not subject the flow meter to back pressure or back flow� The flow meter can be
damaged if the reverse hydraulic horsepower is too great�
• Do not install the flow meter on systems with large degrees of particulate
contamination� Install a minimum filtration of 200 mesh (74 micron) for
trouble-free operation�
• Do not install O-ring seals that have not been lubricated�
