eries UT is a non contact, ultrasonic, continuous level measurement instrument

S

hat is able to provide accurate measurements for liquids, while automatically

t

ompensating for changes in temperature and other environmental conditions.

c
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

isplay. Series UT has two major components, the main control unit UTC and the

d

ensor UTS (connected via a cable).

s

Main (electronic) control unit: If required, this component can be optionally wall

•
ounted, using a wall mount plate, or panel mounted. To ensure proper operation,

m
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

escribed in Chapter 2, Installing Series UT .

d

he Series UT product line comprises two families, UTC-1XX-XXX-X or UTS-1XX-

T

XX-X (25 kHz) and UTC-2XX-XXX-X or UTS-2XX-XXX-X, each with its own

X
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:

NOTE:

It is recommended to use a connector when cutting/adding sensor cables (both
precut and flexible sensors).

re Cut Cable (Non Hazardous)

P

Pre cut sensor cables can be modified to fit longer and shorten length than the one
that was ordered. For example, if you ordered a sensor for the UTS-1X-XXX-X with
a 5 m/16.4 ft cable, you will be able to modify it to a range between 5 m/16.4 ft to
50 m/164 ft, or if you ordered a sensor for the UTS-1X-XXX-X with 35 m/114 ft
cable, you will be able to modify it to fit a range between 5 m/16.4 ft to 100 m/328
ft. The modifications in the cable length can be made according to following tables:

NOTES:

Sensor cable should not be cut below a minimum of 5 meters (16.4 ft) length.

Precautions

• Ensure that the Series UT components are mounted in an area that meets the

stated temperature, pressure and technical specifications.

Ensure that high-voltage sources or cables are at least 3.28 ft/1 m away from the

•

ensor and its cable.

s

Use round cables with minimum diameter of 6 to 7 mm to ensure that the unit

•

remains sealed to enclosure rating listed (IP65/67).

• Ensure that cables are routed correctly and tightened along walls or pipes.

• Ensure that all cables are overall shielded (sensor cable, interface cable, power

cable and current cable).

Installation and operation of this product should be performed according to the

•

nstallation and Operating Instructions; otherwise, the use of this product is

rohibited.

Installing the Series UT Sensor (UTS)

The following procedures describe sensor installation using 1˝ or 2˝ threading and
a correlating locking nut. The installation procedure is the same whether the sensor
is mounted directly on the tank or mounted on a pipe.

NOTES:

If applicable, you can also install the sensor by screwing it directly into the tank or
pipe threading. Ensure that the tank/pipe threading matches the sensor threads.

To Install the Sensor Using 1˝ Threading:

1. Open the required tank (or pipe).

2. Feed the free end of the sensor cable from the inside of the tank through the

aperture at the top of the tank until the sensor is pulled taut against the ceiling.

The threaded end of the sensor should protrude from the top of the tank.

3. Spread silicon grease around the threading to seal against leakage (you can also

use a FEP band).

4. Thread the free end of the sensor cable through a 1˝ locking nut (not supplied

with the Series UT unit). Bolt the sensor into place by securing the nut to the
sensor thread protruding from the top of the tank.

NOTES:

Tighten the nut by hand only. When tightening the nut, hold the lower part of the
sensor.

5. Wire the sensor cable to the main Series UT unit, as described on page 5.

To Install the Sensor Using 2˝ Threading (UTS-1XX-XXX-X (25 kHz) Standard
Range Sensor):

• Follow the procedure described on the previous page for 1˝ threading, using a 2˝

locking nut with the 2˝ BSP/NPT sensor threading.

NOTES:

When installing a thread free flange mounted unit, you will need a 1˝ or 2˝ locking
nut (depending on the thread type used) to secure the sensor to the tank. The nut
can be purchased separately. When installing a threaded flange, ensure that it
matches the Series UT threads.

In order to make a wiring connection, remove the ribbed faceplate covering the
electrical unit using a 3 mm allen wrench. Ensure that the cover is replaced
securely after all wiring connections are completed.

To Wire and Install the Series UT:

1. Install the sensor, as described in Installing the Series UT Sensor, page 4.

2. Route the sensor's cable (C1) from the sensor to the main unit location. Choose

a route without electromagnetic interference (electrical engines, pumps or high
voltage.

3. Wire the sensor's cable (C1) to the main unit, as described in Wiring for the

Sensor Cable, below.

4. Make any optional monitoring or relay cable connections to the main unit, as

described in the instruction manual.

5. Connect the power cable to the main unit.

6. If required, mount the main unit on the wall using the optional wall mount plate.
