The FDT100 Series comprises
advanced-technology water
flowmeters. This series uses
transit-time ultrasonic technology in
which the signal is transmitted and
received alternately between 2 flow
sensors and the “time of flight”
determines the flow rate. The
battery-powered transmitter comes
in the user’s choice of an integrally
mounted display or a remote-mount
version. Applications include both
commercial and consumable water
measurement. Long-term stability
and a wide measurement range
make it possible not only to
measure water consumption, but
also to monitor systems for water
leakage. Because the FDT100
Series has no moving parts, system
pressure loss is minimal and
filtration is not required. Display flow
rate or total at the push of a button.
Installation is aided by ANSI or DIN
flanges in sizes from 50 to 200 mm.
