UTX878

Applications

The AquaTrans UTX878 is a loop-powered, full­featured clamp-on ow ultrasonic transmitter
system for ow measurement of:

• Potable water

• Wastewater

• Discharge water

• Treated water

• Cooling and heating water

• Other liquids

Features

• 4-wire HART output

• 2-wire standard output option

• Low power consumption

• Suitable for pipe sizes from 1/2 in to 20 in (13 mm
to 500 mm) diameter

• Full external keypad

• Large integral display

• Simple meter and transducer installation and
setup

• Velocity, volumetric and totalized ow

• Economical non-intrusive ow measurement

The AquaTrans UTX878 ow ultrasonic transmitter
combines the simplicity of a loop-powered meter
installation with proven, advanced clamp-on ultrasonic
ow transmitter technology. It provides customers with
an economical solution for ow measurement in pipes
up to 20 in (500 mm).

HART Output or 2-wire Standard

The AquaTrans UTX878 comes with HART protocol as an
available output. This protocol requires the meter to be
installed as a 4-wire device. The UTX878 is also available
as a 2-wire device without HART; the 2-wire UTX878 may
be preferable when replacing existing 2-wire devices.

Two-Channel Model

An optional second channel provides the capability
to measure ow at a single point to obtain two-path
averaging of the ow measurement for increased
accuracy.

Uses the Transit-Time Flow
Measurement Technique

The Correlation Transit-Time™ technique uses a pair of
transducers with each transducer sending and receiving
coded ultrasonic signals through the uid. When the
uid is owing, signal transit-time in the downstream
direction is shorter than in the upstream direction; the
dierence between these transit-times is proportional to
the ow velocity. The AquaTrans UTX878 measures the
time dierence and uses programmed pipe parameters
to determine ow rate and direction.
