FTB690 Series turbine meters
electronics offers a durable,
compact, high-precision fluid
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 9000 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 fifteen-point field calibration
curve can be stored in memory.
The FLSC690-BATT is the
replacement lithium battery for the
display electronics. Batteries
provide 9000 hours of use.
