GENERAL INFORMATION
FT430/440/450 INSTRUCTIONS
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
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 congured as alarm outputs. These ow
computers can be password protected to prevent resetting
the total or changing conguration settings.
outputs. Galvanic isolation is provided for most pulse
outputs.
The FT430/440/450 meters are available in wall and meter
mount congurations. The FT430 and FT440 models
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
can also be panel mounted. Some congurations can
be converted from wall to meter or meter to wall after
installation if needed. Consult factory for details.
“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.
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 offers the most exibility.
*Internal power supply is available for the wall mount option only.
