To protect against leakage, seal all pipe
threads with an appropriate sealing com-
pound. Make sure the sealing compound
does not intrude into the flow path.
NOTE: If connecting to new male pipe threads,
burrs and curls can adversely affect accu-
racy. Correct the problem prior to turbine
installation.
NOTE: Do not over tighten the flange bolts. This
may cause the gasket to be compressed
into the flow stream and may decrease the
accuracy of the meter.
Installation near high electromagnetic fields
and high current fields is not recommended
and may result in inaccurate readings.

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:
