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.

Wall Mount. To mount an FT430/440/450 indicator to
the wall, hold the unit in the desired position, mark the
holes in the mounting feet, drill and mount with screws.
A meter-mounted indicator can be converted to a wall
mount using an adapter mounting kit. Contact distributor
for information.
Meter Mount. If the FT430/440/450 indicator was ordered
as a meter mount model, the housing is already mounted
directly to the ow sensor and needs no further installation.
An FT430/440 module can be converted from a wall-
mount to a meter-mount using the mounting kit (contact
distributor) that includes a lower housing and associated
hardware and installs as follows:

1. Remove the strain relief through which the ow
sensor cable runs.
2. Cut the cable to about 6” in length. Carefully strip
the cable jacket to expose the three colored wires
(red, white, and black) inside.
3. Route the wires through the threaded connector
pre-installed in the bottom of the housing.
4. Start the threaded connector into the female thread
on the top of the ow sensor. Be sure to match the
oblong shape on the bottom of the housing to the
depression on the top of the ow sensor.
5. Using an ordinary screwdriver inserted in one side
of the slot (see drawing), tighten the screw as much
as possible.
6. Strip the wire ends, make the connections to the
indicator as shown in Connections Diagrams, and
then use the cover screws to attach the indicator to
the top of the housing.

FT430/440/450 INSTRUCTIONS
K-Factor
At a minimum, every FT430/440/450 ow computer must
be programmed with the “K-factor”. (This is the number of
pulses that the meter produces per gallon of ow.) If you
wish to read in units other than gallons, see below.
The K-factor on any Seametrics ow sensor tting or in-
line meter can be found on the model-serial label. The
line reading K = xxxx gives the desired number. For depth-
adjustable sensors (110, 210, 150, 250 models), use the
calculator on our website.

Menu Navigation
The left/right keys are used to move through the menus
and position the cursor during data entry. The up arrow is
used to scroll through the available values that are to be
entered. (examples: numerical values for K factor entry or
selection of units from the available options) The enter key
(represented on the keypad by the check mark) is used to
save selected entries and in conjunction with the exit tab to
move between menu screens. As one navigates the menus
the current parameter setting is shown and instructions are
displayed for how to change the selected parameter.
