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.

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.

Chapter 3: Basic Setup

This chapter describes how to set up and calibrate Series UT for accurate
measurement monitoring using the basic menu options.

eries UT is supplied with preprogrammed default settings, making it ready for

S

mmediate operation. Measurement readings are displayed on the default screen

i
as soon as the unit is powered on, as described in Default Screen, page 7.

It is recommended that you replace the default tank height value with the actual
tank height, as described in Setting the Tank Height, page 11. When using Series
UT, the tank height is calculated as the distance from the surface of the sensor to
the bottom of the tank. You should enter this value whenever tank height is
required. (For flow measurement, enter the precise flume height.)

The Series UT main menu (shown on page 7) enables you to access the primary
functions for Series UT operation, so that you can change the default settings and
calibrate Series UT, as required. You can define further specialized function options
for Series UT from the additional menu, as described in Chapter 5, Additional
Features.

Wiring the Relays Cable

Series UT’s electrical unit provides connectors at terminal JP26 for up to five
independently programmable relays. The relays can be used to initiate certain
actions, such as controlling pumps, triggering an alarm or sending a warning
message, or when a defined value is reached. (Defining values for the relays is
described in Chapter 3, Basic Setup.)

To Wire the Relays Cable to JP26 Using VDC Power:

1. Thread the required cable through apertures (C2/C3) located at the base of the
electrical unit.

2. Connect the relay cable wires to the appropriate posts, as shown in Figure 11:
Electrical Unit, page 5.

NOTES:

Close the glands to ensure sealing. The O-ring is suitable for one use only. If your
unit is equipped with conduits instead of glands, aperture C3 is not available. Use
aperture C4 instead. Do not exceed 250-inch pounds torque on installation of
conduit.

or Gallons of flow, depending on the
value that you have selected from the following list (you can define the X value): 1,
10, 100, 1000, 10000, 100000. An electrical pulse will be generated whenever the
relay total flow value will be larger than the value selected from the list. You can
also choose a pulse width between 20 to 2000 milliseconds with a resolution of 10
milliseconds to match your equipment requirements. For example, the relay will
generate a pulse with a duration of 1000 ms, and each time the value of flow will
reach 10,000 M

You can set up to five relay switches for Series UTS. Each relay enables you to
define open and close values for the switch, for functions such as triggering an
alarm.

The relay values function as follows:

• Open value: (Default = 0) The relay opens if the level measured in the tank is
higher than the entered open value.

• Close value: (Default = 0) The relay closes if the level measured in the tank is
lower than the entered close value.

NOTES:

The close value must be lower than the open value for each relay, otherwise an

message is displayed.

An message is displayed if a relay value is greater than the tank height
value.

In case of no measurement (caused by electronic problem or acoustic
interference) relays will switch to Close state.

For safety reasons, relays parameters will reset when the following parameters will
be modified: Tank height, relays indication mode (Level/ Distance/Flow),
measurement mode (except when changing from Level to Distance and vise
versa) Flume/Weir type, measurement units, strapping table.

The result of the totalization amount is updated every 30 seconds.

etting the 20 mA/4 mA Levels

S

Series UT enables you to set height, volume or flow values to be used as 20 mA
and 4 mA marks. These values can be used for remote monitoring of tank level,
volume or flow using an analog meter. The analog output indicates the current
depth in the tank, or the current flow level, as a point on the meter range between

mA and 20 mA. The default value for 20 mA is the tank height (or the maximal

4

olume value), and for 4 mA the default value is 0 (or the minimum volume value).

v

NOTES:

The values for 20 mA and 4 mA must be different, otherwise an message
is displayed. Both must also be less than the tank height value, otherwise an

message is displayed.

In both distance and level measurement modes, the dead zone area affects the
maximum values that can be used for 20 mA/4 mA levels. For UTS-X1X-XXX-X
models, the maximum 20 mA/4 mA value is tank height minus 0.6 m/1.9 ft. For
UTS-X2X-XXX-X and UTS-X3X-XXX-X models, the maximum 20 mA/4 mA value
is tank height minus 0.4 m/1.3 ft.

NOTES:

VOLUME values in 4 to 20 mA are represented by six digits (the same applies for
FLOW values). TOTALIZATION values are represented by large numbers and
therefore require two separate screens for high (H) and low (L) numbers (as

NOTES:

The operation modes are not relevant for flow applications. If one of the

STORAGE I, STORAGE II or PROCESS options is selected when Series UT is in
FLOW application mode, an warning message is displayed and Series

UT reverts to distance mode. You must then reset the unit to flow mode.

Liquid Modes

Three modes are available for Series UT liquid application models. Each mode is
recommended for use as follows:

• : Recommended in the following conditions:

• Wavy surfaces

• Slow filling/emptying rate

• Applications where the sensor is installed near the tank wall

• : (Twice as fast as STORAGE I.)
Recommended in the following conditions:

• Reasonable surface conditions

• Applications requiring fast readings

NOTES:

STORAGE I and STORAGE II liquid modes are not suitable for measuring
surfaces with foam, since these modes cannot perform signal processing.

• : This mode is suitable for applications where a fast reading is more

important than precision. A reading will be displayed within a short
time, even if the signal processing procedure was not completed.
Recommended in the following conditions:

• Foamy top surface

• Presence of agitation

• Presence of vapor

• Applications requiring very fast readings

Setting the Scan Distance Values

Figure 15: Scan Distance Process

Up to eight interfering signals (false echoes) can be located by Series UT and
stored in its memory. The false echoes, which may be caused by obstructions such
as a tank agitator or a side wall, can generate false readings and so interfere with
the true scanning of the tank contents. Defining interfering signals is done while the
tank is empty.

Each scan distance reading is stored as an interfering signal until a reading is
achieved that indicates the true echo. If eight interfering signals are already stored
and a ninth reading is received, the first value stored is deleted and the new one
saved.

Chapter 4: Series UT Open Channels

This chapter describes how to set flow measurement parameters for open channels
using Series UT models, and explains the flume/weir codes methodology used
when setting up flow measurements.

NOTES:

Refer to Chapter 3, Basic Setup, for an explanation of accessing and using the
Series UT main menu and function buttons.

Selecting the Flow Measurement Settings

The PARSH.FLUM function in the main menu enables you to select one of the
preset flumes/weirs settings for flow measurements.

When setting flow measurement parameters, the flume/weir type value (X) is
entered first, followed by the letter (U) or (E) as an indication for American or
European open channel flow standard, and followed by the code value (YY) that
represents the appropriate flume/weir dimensions, in the following format: .
The default is European standard. The open channel types and codes are
described in Open Channels Flow Measurements, page 14.

If you wish to insert custom flume measurements, you must enter .001 for this
function. This entry will automatically initiate an additional menu function (Pr 1),
enabling manual insertion of custom flume values in an accordance table, as
described in Chapter 5, Additional Features.
