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 Description terminal The Ultrasound Controller should be protected from dust and water. -

Air Sensor cables. If shielded cable glands are not used then terminal 11 or 16 on the D72, DP72 or terminal 14 or 19 on D128 can be connected to the cabinet instead. Note that Air Sensor PAC needs a short jumper cable. To minimize the risk of electric interference and noise, see Electric Noise page 10. -

This improves bubble detection. However only one Air Sensor CQS can be connected to one D72. Settings should be set for air sensor 1 (setttings for air sensor 2 is disabled when air sensor 1 is set to CQS). - Page 18 Ndata Electric interference will show itself as being unstable with Air in the Air Sensor. To minimize the risk of interference it is important that sources of interference like frequency inverters should use shielded cables between inverter and motor. Also any unshielded part of the cable between the Air Sensor and Ultrasound Controller should be short.

Page 20: Level Switch Type And Technique
Level Switch Type and Technique There are two different measuring techniques: Echo and WR (Wall Reverberate). The different Level Switches are optimized for each technique. Level Switch RS works well with the WR- technique and do not work well with Echo-technique. Level Switch MK has a soft silicone surface adapting to the container surface and works well with Echo-technique and does not work well with the WR-technique. -

In an empty container there is no dBnoise echo. If the echo strength is not higher than 10dB above there can be difficulties AQ M-Tech AB Ultrasound Controller Manual... - Page 32 measuring the level. Make sure the echo is reflected properly back to the level sensor and that the Level Switch is horizontal. The bottom thickness and material also influences the echo strength, see Mounting the Level Sensor. If bottom thickness is such that resonance is not at 2MHz the echo is weaker.

Page 33: Gel Distance Mode
The mA output can be set to output distance (0% Level = 4mA, 100% Level = 20mA) or Signal strength (0dB = 4mA, 85dB = 20mA). It is adviseable to check the signal strength also during testing. AQ M-Tech AB Ultrasound Controller Manual... -

Page 37: Measuring Gel
The echo is bouncing off the reflecting surface, either the opposite container wall or the pin on GF90. Sound pulses are constantly being transmitted and the returning echo is constantly being measured. AQ M-Tech AB Ultrasound Controller Manual... -
Page 38: Mounting The Level Switch
The echo strength is measured and relative attenuation is calculated by comparing to the calibrated echo strength. The relative attenuation is calculated by taking into account the ultrasound travel distance. The result is relative attenuation measured in dB/m and it is fairly GEL- proportionat to gel concentration. -
Page 39: Settings
0% = 4mA, 16% = 20mA. Gelconcentration will not be affected by any WR-measurements of air and therefore since air gives high attenuation of the echo it will show as high concentration of gel. AQ M-Tech AB Ultrasound Controller Manual... -
Page 40: Calibration
Settings for GF90: Note that GF90, when used as gel sensor, can only be connected to G72, Type GP72 or G128, this is because GF90 in this case uses frequency 4MHz. Set to as many ECHO-DISTANCE : 90mm, FREQUENCY: must be 4MHz If GEL-TYPE GF90 as are connected. -
