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.
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.
Square Wave Output
To achieve square wave output, reference
Wiring Diagram 2 and use an Electronic Digital
Meter Battery Kit (sold separately) for battery
power. The terminal block and battery location
are located on the back side of the module.
Access as follows:
1. Remove the four Phillips-head screws from
the front of the module and lift the module
from the turbine.
2. To change terminal block connections,
loosen the appropriate screws. Reconnect
the wires in the proper positions and tighten
the screws.
3. Install the batteries. Make sure the positive
post is in the correct position.
4. Position the module on the turbine housing.
To avoid moisture damage, make sure the
seal is fully seated. Tighten the four screws
on the front of the module.
