The FT430/440/450 ow computers are microcontroller-based
indicator/transmitters that interface with pulse output ow sensors to
compute and display ow rate, ow total, and also generate output
signals representing ow. The FT430 and FT450 have one scaled pulse
output and one pulse pass through. The FT440 has two scaled pulse
outputs. Galvanic isolation is provided for most pulse outputs.

The FT450 is battery powered while the FT430 may be powered by an
external DC power source or an optional internal AC power supply*.
The FT440 is a “two-wire” or “loop powered” device, meaning that
it is powered by the 4-20 mA loop circuit itself. An optional internal
AC power supply* is available for the FT440 with dual 24 and 12VDC
outputs to power both the loop and sensors requiring more power than
the loop can supply.

Pulse and 4-20mA analog outputs can be used to signal external devices,
e.g. certain metering pumps and water treatment controls. Alternatively,
one or more pulse outputs can be congured as alarm outputs. These
ow computers can be password protected to prevent resetting the
total or changing conguration settings.

The FT430/440/450 meters are available in wall and meter mount
congurations. The FT430 and FT440 models can also be panel mounted.
Some congurations can be converted from wall to meter or meter to
wall after installation if needed. Consult factory for details.

Order the FT440 only if a 4-20mA output signal is a requirement and
the FT450 if internal battery power is needed. Otherwise the FT430
oers the most exibility.

*Internal power supply is available for the wall mount option only.
