The FDT-80 Series has been discontinued. Please see the FDH-1 Series as a possible alternative or contact our Flow Engineering Department.
The FDT-80 Series of portable transit time flowmeters
feature the world’s most advanced non-invasive flow
measurement technology, providing a measuring
system with unsurpassed accuracy, versatility, ease
of installation and dependability. Although designed
primarily for cleaner liquids, the flowmeter can also
reliably measure liquids containing moderate amounts
of suspended solids or aeration.
FDT-80 is designed for long or short term flow
measurement surveys on full-pipe liquid systems and
is ideal for verifying calibration of permanently
mounted flowmeters of all types. The flowmeter
features a tactile keypad, 24-hour battery
(rechargeable), and a 128 x 64 pixel,
back-lit graphics display - all
integrated into a rugged,
watertight enclosure. The FDT-80
systems utilize proprietary dual timebase
time expansion algorithm, advanced
DSP and digital cross-correlation. The cost effective
and versatile FDT-80 flowmeter comes complete with
all accessories necessary for measuring piping
systems from 50 to 2540 mm (2 to 100").
FDT-80 Series has a flow measuring range that
exceeds 4000:1. This feature allows the instrument to
measure normal process flow rates as well as flows
resulting from leaks in piping and valves.
User configurable rate and totalizer units include: feet,
gallons, ft3, million-gal, barrels, acre-feet, lbs, meters,
liters, m3, million-liters and kg. Non-invasive clamp-on
transducers are simple and cost efficient to install.
Since the transducers do not contact the liquid, fouling
and maintenance are eliminated.
Automatic Reynolds Number compensation
assures accurate measurements through the laminar,
transition and turbulent system flow regions. An
integral 24 hour rechargeable battery allows extended
operation when AC power is not available. Both AC
and cigarette socket style power adaptors (battery
chargers) are included. Compartmentalized and
padded carrying case keeps the FDT-80 meter and all
of its accessories organized and protected.
