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 150-lb ANSI
flanges in sizes from 2 to 8".
