The FDT100 series has been discontinued. Please see the FDT500 Series as a possible alternative or contact our flow dept. Engineering department.
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".
