FTB380 Series turbine meters with
microprocessor-based electronics
offers a durable, compact, highprecision fuel measurement device,
with total and rate indication.
Information is clearly displayed on
a large 6-digit liquid crystal display
with only 2-point floating decimal
for totals from 0.01 to 999,999.
All operations are easily performed
with only 2 buttons.
The basic unit and display are
powered by 2 lithium batteries,
providing up to 4000 hours of use.
Automatic “on” and “off” extend
battery life. Manual “on” allows
view of the display on demand.
Cumulative total, batch total, and
rate of flow are standard. A singlepoint field calibration curve can be
stored in memory.
The turbine meter can also be
ordered without display electronics.
A special pulse output model
(FLSC790-P-ND) must be ordered
to obtain an open collector current
sinking output operated on 9 to
35 Vdc. The output is a square wave
pulse with a 3-wire connection.
Accessories for Turbine
Meters with the Display
The FLSC790-90D is a 90°
mounting adaptor designed to allow
displays to be mounted 90° from the
standard position.
