Dwyer UTS - Manual (Page 3)

Chapter 1: Introduction
Series UT is a non contact, ultrasonic, continuous level measurement instrument
that is able to provide accurate measurements for liquids, while automatically
compensating for changes in temperature and other environmental conditions.
Series UT is designed for applications such as process tanks, storage vessels,
open air piles, open channels, and so on.
Series UT is a four wire, low voltage device, and is available with a graphic LCD
display. Series UT has two major components, the main control unit UTC and the
sensor UTS (connected via a cable).
• Main (electronic) control unit: If required, this component can be optionally wall
mounted, using a wall mount plate, or panel mounted. To ensure proper operation,
the unit must be installed up to 200 m (656 ft) from the sensor.
• Sensor and data cable: The sensor is supplied with the data cable attached.
• The installation procedure and wiring connections for these components are
described in Chapter 2, Installing Series UT .
The Series UT product line comprises two families, UTC-1XX-XXX-X or UTS-1XX-
XXX-X (25 kHz) and UTC-2XX-XXX-X or UTS-2XX-XXX-X, each with its own
models (as listed below). A variety of sensors are available for Series UT, suitable
for different ranges.
The following diagrams show the front and side views of UT, and its dimensions:
The following schematic diagrams show the wall mount and panel mount options,
