2. Introduction
Ultrasound Controller
Ultrasound Controller uses ultrasound to make measurements of liquids. It can detect bubbles in
flowing liquid or it can detect presence of liquid behind a container wall or it can measure
continuous liquid level. The Ultrasound Controller has four different modes of operation:
Air Sensor mode: The Air Sensor monitors the presence of gas or particles in flowing liquid. The
Air Sensor is very reliable and easy to use. Two Air Sensors can be connected to one
Ultrasound Controller.
Level Switch mode: The Level Switch is a small sensor which attached to the outside of the
container can sense the presence of liquid inside the container without making hole in the
container. Four Level Switches can be connected to one Ultrasound Controller.
Level Sensor mode: Continuous liquid level is measured with a Level Switch attached under the
container bottom (no hole in the container). High accuracy is achieved with a second Level
Switch measuring liquid sound velocity. Two levels can be measured with one Ultrasound
Controller.
Gel Distance Sensor mode: Continuous gel distance is measured with a Gel Distance Sensor.
This mode is only available in GS72.
Gel Sensor mode: Gel Sensor GF90 installed inside or Level Switches attached outside the
container can sense the presence of gel in the container. Four gel sensors can be
connected to one Ultrasound Controller.
The software version of the Ultrasound Controller is shown briefly on the display when power is
switched on. The software version can also be found in the HELP-menu. Software versions may
differ slightly and therefore it is usually better to use a manual version corresponding to the
software version, even though a later manual version can have less errors.
Installing Ultrasound Controller D72, G72
The Ultrasound Controller should be protected from dust and
water. It is made to be attached to a DIN-rail, to which it
snaps easily and can be removed by pushing up and bending
the top out. Usually it is installed in an electric cabinet. The
connector terminals can be removed by pulling the connector
straight out. Connections for terminal 1-7 and D-sub, see
table. Connections for terminal 8-17 depend on the selected
mode, see table in the corresponding chapter.
The Ultrasound Controller should be installed in accordance
with national regulations. A person with
the required knowledge should
perform the installation.

Installing Ultrasound Controller DP72, GP72
The Ultrasound Controller DP72 and GP72 should be protected
from dust and water. It is made to be attached to a DIN-rail, to
which it snaps easily and can be removed by pushing up and
bending the top out. Usually it is installed in an electric cabinet.
The green connector terminals can be removed by pulling the
connector out. Connections for terminal 1-7 and D-sub, see
table. Connections for terminal 8-17 depend on the selected
mode, see table in the corresponding chapter.
The Ultrasound Controller should be installed in accordance
with national regulations. A person with the required knowledge
should perform the installation.
Installing Ultrasound Controller D128, G128
The Ultrasound Controller D128 and G128 is protected
according to IP65 and can be installed outside a protecting
cabinet. The bottom plate must be removed in order to access
the terminals. Remove dummy covering and insert cable
glands as needed. There are 3 small and 4 big cable glands.
There should be only one cable in each cable gland to achieve
full IP65 protection. The pressure compensation element can
be moved to different place but must not be removed
completely. Make sure the gasket is in place when screwing
the bottom plate. Connections for terminal 1-10, see table.
Connections for terminal 11-20 depend on the selected mode,
see table in the corresponding chapter.
The Ultrasound Controller should be installed in accordance
with national regulations. A person with the required knowledge
should perform the installation.

Keep MENU-button pressed to scroll continuously. Press also BACK-button while pressing
MENU-button to scroll backwards. Menu-text, parameter-names and parameter-values as seen on
the display is here in the manual written in blue italic.
Sensor MODE and the start-screen
When power is applied to the Ultrasound Controller it displays the software version on the LCD-
display, followed by the start-screen. Depending on which mode is set; the corresponding start-
screen will be shown. The Ultrasound Controller can be set to either Air Sensor mode, Level
Switch mode, Level Sensor mode or Gel Sensor mode. When the Ultrasound Controller is
powered on for the first time Set sensor MODE is displayed. Press the MENU-button to scroll to the
desired mode and press the SELECT-button to select it. Sensor mode can be changed again in
ADVANCED SETTINGS. Here is a map of the menu-system:

4. Electric Noise
Ground Connection and Sensor Cable
All sensor cables must be shielded. The unshielded part of the
sensor cable should be maximum 40mm. The sensor cable may not
be extended.
Best connection to ground is achieved by using grounded cable
glands on the sensor cables. Only if the sensor cable is not grounded
via the cable gland, is it recommended to connect terminal 16 on the
D72, DP72, G72, GP72, GS72 or terminal 19 on D128, G128 to
ground, near the transmitter as shown in the picture.
Electric noise, with frequency around 2 MHz, entering the sensor
cable can cause measurement problems and is better to be minimized by using shielded cables
and by not routing the sensor cables along high voltage cables connected to a variable frequency
drive.
Noise from Variable Frequency Drives
Variable frequency drives produces noise which exist mainly in the cable connecting the variable
frequency drive to the motor. It is good if this cable is shielded and not routed along the sensor
cables. The variable frequency drive also produces ground current noise, caused by noise
travelling capacitively to ground inside the motor. To reduce
such ground current, a common mode filter can be used. The
most simple common mode filter is a ferrite clamp, clamped on
the three wires coming out of the variable frequency drive. An
even more efficient filter is a toroid. It consist of a ferrite toroid
with the three wires, connected to the 3-phase output of the
variable frequency drive, threaded through the toroid as shown
in the picture.
The filter in the picture is very good and is made of two ferrite
toroids. The three wires are wound three times through the
toroid. The ground wire do not go through the toroid.
Ferroxcube toroid TN25/15/10-3F3 is suitable for wires up to
2,5mm2and it is shown in the picture. Alternatively, EPCOS
toroid B64290L616X830 can be used. If the wires do not fit, a
larger toroid can be used. Ferroxcube toroid of material 3F3 or
EPCOS toroid of material N30 or Amidon toroid of material 77
are suitable for filtering frequencies around 2MHz.
5. Ex-installation with ex-barriers
Ex-barriers are not shielded so if ex-barriers are
used, Ex-barrier shields must be inserted on
each side of the group of EX-barriers connected
to each Ultrasound Controller (see picture). The
ex-barrier connects the sensor cable shield to
ground which makes it possible for ground
currents to enter. Because of this, minimizing
ground currents is very important especially
when EX-barriers are used.
