FLOW
UNIVERSAL FLOW TRANSMITTER
MODEL UFT-1
DESCRIPTION
The Model UFT-1 Universal Flow Transmitter is a
solid-state, digital signal converter designed to operate
with Data Industrial 200 Series flow sensors. Both ana-
log (4-20 mA) and pulse outputs are available. The
Model UFT-1 may be mounted in an optional NEMA 4X
enclosure or with digital display of gpm or totalized flow
(in a non-watertight enclosure).

APPLICATION
Analog Output (rate)
DIMENSIONS
The Model UFT-1 analog transmitter converts a Data
Industrial digital flow signal into a precalibrated 4-20 mA
signal. It must be calibrated for each Data Industrial flow
sensor installation. The pipe type, size, and maximum
flow rate must be specified at the time of order if 4-20
mA output is to be used.

Pulse Output (totalization)
Pulse
Out –
The Model UFT-1 pulse output divides the Data
Industrial digital flow signal by a jumper-selectable 10 or
100 position to provide a more usable digital pulse. The
pulse output is normally used where flow totalization is
required. A simple conversion formula, using the flow
factors for Data Industrial flow sensors on the next page,
can convert the digital pulses to totalized gallons.

The pulse output is an optoisolated transistor switch that
can be wired to source or sink pulses to totalizer equip-
ment.
