The Series UV In-Line Polysulfone Flowmeter measures
the flow of water, air, and other compatible media at tempera-
tures up to 212°F (100°C) and pressures up to 150 psi (10.34
bar). This flowmeter’s highly corrosion-resistant materials suit
it ideally for use with de-ionized water and ultra-pure applica-
tions, including food processing, medical equipment and
reverse osmosis water systems.
INSTALLATION
1. Select an indoor (only) location that is free from excess
vibration, within the specified temperature limits, and away
from direct sunlight. (Polysulfone is adversely affected by ultra-
violet light.)
2. Remove hollow plastic shipping tube from inside flow body.
3. Handle carefully. Hand-tighten aluminum ring.
O-Rings will seal if hand tightened only. Do not
overtighten the
adapters and fittings.
4. Install the flowmeter in an exact vertical plane, one that is in
proper alignment with the existing plumbing. Use wall or other
structural supports at the top and bottom of the unit. Do not
allow the instrument to support the weight of pipes or tubing.
5. Use pipe thread sealant tape. Do not
use pipe dope com-
pounds, which can craze and crack the polysulfone housing.
Hand tighten system pipe fitting to adaptor fitting. If additional
torque is needed to seal pipe joint, use strap wrench on adap-
tor fitting. Maximum torque is 22 Foot - Pounds.
6. If using solvent-based glues like PVC cement, in the piping
system, do so with the meter’s body removed until glue has
cured, then purge the system before re-installing. Do not sol-
der brass fittings with the body installed, because the heat
generated to solder the brass fittings will damage the flowme-
ter.
CAUTION: Ball valves and solenoid valves can have a “water
cannon” effect on opening, creating pressure that exceeds the
warrantied ratings and will damage the flowmeter.
