Cut to Length The meter housing can be
shortened by the customer. Each meter has
a "dotted" line feature molded on the top
surface of the housing tube. The housing
can be cut up to this line without harming
any internals.
Most glue on fittings will fit without in-
terfering with the computer display area.
However, the customer should check all
parts before attempting cut.
For NPT Fittings wrap all connections with
3 to 4 wraps of thread tape. Make sure the
tape does not intrude into the flow path.
3. Attach meter with arrow pointed in the
direction of flow.
4. For NPT Fittings - Hand tighten the meter
at the housing ends. Do not use a wrench
or similar tool to tighten. This can damage
the housing.
5. For Flange Fittings - Customer to provide:
• Ring Gaskets or Full-Face Gaskets ap-
proved for use with ANSI flanges and the
fluid being monitored (2 required).
• 5/8" bolts and nuts: 4 per side for 3-inch
meters; 8 per side for 4-inch meters.

The terminal block is identified as follows:
Pin #1 6 volt square wave (not used)
Pin #2 +9 to 35 volt DC Input
Pin #3 Common Ground
Pin #4 Open Collector signal Output
Torque bolts using a star pattern to 25 ft-lbs.
Supplied flanges are two-piece and allow
the meter to be oriented regardless of the
mating flanges position.
Conditioned Signal Output
Module Wiring
This conditioned signal output module can be
wired to provide an open collector signal output
or 6-volt square wave output.
Open Collector Signal Output
To achieve an open collector signal output,
reference Wiring Diagram 1. The terminal block
is located on the back side of the module. The
module is factory assembled for open collec-
tor signal output. Please provide the (820 ohm
minimum) resistor.
Ten feet (3 m) of cable is provided with the
module. Trim it to desired length or extend it as
necessary. Distances up to 5,000 feet (1,524 m)
can be achieved for open collector signal output.
