INSTALLATION & OPERATION INSTRUCTIONS
FL-2000 - FL-2069
Acrylic block flowmeters are available in various
sizes and ranges, with direct reading scales in both
SAE and SI units for air and water (see charts on
other side). For other gases or liquids, special scales
can be provided.
If
you use this meter with fluids
other than air or water, please consult chemical
compatibility data for possible effects on the meter.
These meters are manufactured of durable acrylic and
if properly installed and maintained, will provide
long-term trouble-free operation.

UNPACKING
Precautions have been taken to prevent any damage
from occurring during shipment. However, if the
meter is received damaged,
report it to the carrier
immediately.
Before installing, verify that you have
the model and flow range required.
ACHIEVING ACCURATE F'LOWRATES
To obtain an accurate flowrate, the float must be read
at the position indicated on the meter. If the meter
uses a ball float, the flowrate is determined by reading
the center of the ball. Additionally, the flowmeter
should be installed in a manner, which minimizes
both external vibrations and internal flow variations.
Special care should be taken so that the connections
to the meter's inlet and outlet fittings do not overly
restrict the liquid or gas flow being metered. This
could result in a reduced flow volume, preventing the
meter from reaching its maximum flowrate .
Furthermore, internal pressures could be affected,
which can cause inaccurate flow readings. On start
up, slowly purge any fluid trapped in the meter.
INSTALLATION
These meters are supplied with 5/8" or 7/8" hex's on
the inlet and outlet fittings. When installing 1/8-27
MNPT or '/4-18 MNPT fittings into the meter,
place
the appropriate size wrench on the hex to prevent
the inlet/outlet fitting from rotating. Torque only
to 60 in-lbs.
Failure to do so will cause the fitting to
rotate, and may damage the meter body, causing leaks
and/or meter failure.
Use pipe thread sealant or
Teflon® tape to ease installation and provide a better
seal. This meter is supplied with #10-32 threaded
inserts for mounting. When installing, use slotted
screws and torque to a maximum of 35 in-lbs.
Mounting dimensions are shown in Figure I.
CAUTION
THIS FLOWMETER IS DESIGNED FOR USE WITH NON-HAZARDOUS FLUIDS AT PRESSURES UP TO 100 PSI (690 KPA) AND TEMPERATURES
UP TO 150 °f (65 °C). Do NOT USE HAZAROOUS FLUIDS AND 00 NOT EXCEED TEMPERATURE OR PRESSURE LIMITS. USE WITH
HAZARIXJUS FLUIDS OR EXCEEDING THE PRESSURE AND TEMPERATURE LIMITS MAY CAUSE FAILURE WHICH COULD RESULT IN INJURY.
