2. Introduction

Ultrasound Controller

Ultrasound Controller uses ultrasound to make measurements. 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 Sensor mode: The Level Switch attached to the outside of the container can sense the

presence of gel inside the container without making hole in the container. Four single gel-

levels can be measured with one Ultrasound Controller.

Installing the Ultrasound Controller D72 and G72

The Ultrasound Controller D72 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 a cabinet.

The green connector terminals can be removed by pulling

the connector out.

The Ultrasound Controller should be installed in accordance

with national regulations. A person with the required

knowledge should perform the installation.

Installing the Ultrasound Controller DP72

The Ultrasound Controller DP72 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 a cabinet. The green

connector terminals can be removed by pulling the connector

out.

The Ultrasound Controller should be installed in accordance

with national regulations. A person with the required knowledge

should perform the installation.

Installing the Ultrasound Controller D128

The Ultrasound Controller D128 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 to

connect the cables (8 screws). Remove dummy coverings and

insert cable glands as many as needed. There are 3 small and 4

big cable glands, see page 37. There should be only one cable

in each cable gland to achieve IP65 protection. The pressure

compensation element can be moved but must not be removed.

Make sure the gasket is in place when screwing the bottom

plate.

The Ultrasound Controller should be installed in accordance with

national regulations. A person with the required knowledge

should perform the installation.

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. Then press MENU button to scroll to the

desired mode and press SELECT button. How to change sensor mode once it has been set is

described in ADVANCED SETTINGS.

4. Air Sensor Mode

In Air Sensor mode the Air Sensor is used to measure the presence of bubbles in flowing liquid.

One or two Air Sensors model SAC, PAC, FCS or FCP can be connected to one Ultrasound

Controller.

Quick start guide

Install Air Sensors according to instructions in the Air Sensor Manual.

Connect cables, see page 6 or 7 and 10.

Switch on external power supply.

Read about navigating the menu system, page 8.

Display show: SET sensor MODE. Press MENU button to scroll to Press SELECT for Air Sensor

mode. Confirm by pressing SELECT button.

Go to SETTINGS to set parameters, page 11.

Fill Air Sensor 1 (AS1) with liquid. Select Calibrate LIQUID AS1 and Press SELECT button one

second.

Empty Air Sensor 1 (AS1) of liquid. Select Calibrate AIR AS1 and press SELECT button one

second.

Do the calibration in the same way for Air sensor 2 (AS2). The calibration order can be

mixed for sensor and liquid/air.

Do a simple validation: AIR should be indicated when the Air Sensor is empty and LIQUID

when it is filled with liquid.

Go to SHOW DATA for a more thorough validation of the calibrated values, page 13.

Ready.

Functional Description

Bubbles in the liquid flowing through the Air Sensor are monitored by the use of ultrasound. Inside

the Air Sensor two low intensity beams of ultrasound are transmitted across the liquid-path in

directions perpendicular to the liquid flow.

If a bubble moves into one of the ultrasound-beams the ultrasound will be partially deflected and

the intensity of the ultrasound decreases. The controller constantly measures the intensity of the

ultrasound and if the intensity becomes lower than the threshold it detects a bubble. Dense

particles in the liquid can also deflect the ultrasound in a similar way and can therefore be

detected.

The measurements of very low sensitivity and very very low sensitivity uses a different

measurement technique. It measures how ultrasound vibrations in the Air Sensor walls are

dampened by the presence of liquid inside.

The measurement accuracy depend on how well the Air Sensor is calibrated, the flow-rate, the

type of liquid, how the Air Sensor is mounted and weather there is a single bubble or many

bubbles and the Air Sensor size.

Orientation of the Air Sensor

If the Air Sensor is mounted horizontally orientation is important. Liquid flowing through the Air

Sensor tends to pull bubbles towards the center of the tube but when flow rate decrease bubbles

rises to the top. The Air Sensor is more sensitive to bubbles at the top if it is rotated so that the

cable connector (and label) is facing up. If instead low bubble sensitivity is desirable rotate the Air

10 Ultrasound Controller Manual

Sensor so that the cable connector (and label) is facing down. This makes the Air Sensor less

sensitive for bubbles at the top of the tube.

Setting lowest possible sensitivity for bubbles

If mounted horizontally rotate the Air Sensor so that the cable connector is facing down.

The FILTER setting determines the delay (response time) for detecting air. Consider what can be

the longest acceptable delay for detecting air and set FILTER accordingly: delay 0,3s or longer (do

not set it to integrate). Bubbles that quickly come and go will then pass undetected.

Set the SENSITIVITY to low. SENSITIVITY can also be set to very low or very very low, but these

settings uses a different measurement technique where the presence of liquid is detected

regardless of bubbles. This technique is less reliable and is sensitive to temperature changes and

works only on diameters > 16mm. Don’t use it if there is more than +- 5°C temperature variation

during measurement and calibration. Try first set SENSITIVITY to low and FILTER to delay 0,3s or

longer. If there is still unwanted detections of bubbles, then change the setting of SENSITIVITY to

very low or very very low.
