Page 9: Air Sensor Mode
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 AQ Elteknik AB 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. FILTER setting determines the delay (response time) for detecting air. -
Page 11: Connecting The Air Sensor
Delay means that air will be indicated when air has been continuously detected for a time longer than the delay time. FILTER delay SENSITIVITY Long and low is useful if some quantities of bubbles should be undetected. AQ Elteknik AB Ultrasound Controller Manual... -

Sound velocity in the Air Sensor With sensitivity set to low, medium or high and with two liquids having different sound velocities in the Air Sensor and with these liquids not well mixed, there can be false indication of air. - Page 15 The reason for this can be: Calibration of LIQUID has been done with air or liquid having lots of bubbles or particles attenuating the sound. Or wrong settings of Air Sensor Type or Diameter. Or Air Sensor is wrongly connected. Or Air Sensor is faulty AQ Elteknik AB Ultrasound Controller Manual...

Page 16: Level Switch Mode
5. Level Switch Mode In Level Switch Mode the Level Switch measures a single level from the side of the container. It measures the presence or no presence of liquid behind the container (or pipe) wall. The Level Switch senses through the wall AND no hole is needed. Four Level Switches can be connected to one Ultrasound Controller. -

Mounting the Level Switch How to mount the Level Switch on the container is described in Level Switch manual. Level Switch start-screen Lev Sw When power is applied, the Level Switch start-screen is displayed showing on first line to the right signifying this is Level Switch start-screen. . On the second line to the right is written 1234 which shows the state of each of the four relays. -

Page 22: Level Sensor Mode
6. Level Sensor Mode In Level Sensor mode a level sensor is attached at the bottom of the container and measures the continuous liquid level. The level sensor is attached outside the container and senses through the bottom (no hole is needed). A velocity sensor can also be attached, measuring sound velocity. -

strength is shown in dB. Small adjustments can be made of the angle of the level sensor and the thickness of the silicone layer in order to achieve maximum echo strength. Calibrate liquid once more. Then keep the level sensor in place until the silicone cures. Mounting the velocity sensor A velocity sensor (= Level Switch) must be mounted so it can measure the echo bouncing at the opposite container wall. -

Page 28: Gel Sensor Mode
7. Gel Sensor Mode Gel Sensor Mode can measure the presence and concentration of gel media, used in chromatography systems. It can measure single levels of gel and gel concentration behind the container wall. The Gel Sensor senses through the wall (no hole is needed). Four single levels can be measured with one Ultrasound Controller. -

the actual container is recommended. Any welding-joint in the wall should be avoided as it can refract the sound-beam. The ultrasound beam behaves similar to a light-beam, the direction of the echo depend on from what angle it hits the reflecting surface. The sound beam is approximately 1cm in diameter. Obstructing objects in the path between sensor and the reflecting surface may cause the beam to divert. -
