Section 2 General information The information in this manual has been carefully checked and is believed to be accurate. However, the manufacturer assumes no responsibility for any inaccuracies that may be contained in this manual. In no event will the manufacturer be liable for direct, indirect, special, incidental or consequential damages resulting from any defect or omission in this manual, even if advised of the possibility of such damages. -
Page 8: General Sensor Information
2.2 General sensor information The SONATAX sc is intended for the measurement of sludge levels in water. Use in other media without test of the materials (refer to Section 1 Technical data on page... -
Page 9: Functional Principle
Echos from layers that are further away are quieter (weaker) than those which are closer. The SONATAX sc compensates for this attenuation. The result is indicated on the SONATAX sc as a profile. The data is found in the probe menu SENSOR SETUP > TEST / MAINT >... - Page 10 The vertical line represents the threshold. The sludge level is detected by the SONATAX sc at the point at which the profile exceeds this threshold for the first time viewed from above (analogous to the abovementioned definition of the sludge level). In the graphic, the detected sludge level is identified by a mark on the Y axis.

Page 11: Section 3 Installation
The sensor is not suitable for installation in hazardous areas. The SONATAX sc can be used with an sc100, sc200 or with an sc1000 controller. Installation instructions are found in the handbook of the controller. -

Installation 3.4 Install sensor The SONATAX sc is intended for installation with a tank edge attachment. For more information, refer to the installation instructions of the tank edge attachment. Note: Do not begin with the installation of the tank edge attachment before... - Page 14 Installation Figure 7 Round tank graphic Figure 8 Rectangular tank graphic At a suitable measurement location, there should be: • Sufficient sludge present for the measurement, and • A calm, clear phase above the sludge level In the examples shown, area (A) shows only very little or no sludge, while in the area (C) above the sludge layer, sludge clouds may disrupt the measurement.
-
Page 15: Determine The Distance To The Tank Edge
(Figure 3.4.1.1 Determine the distance to the tank edge If the SONATAX sc is installed on the tank edge (i.e. not on a scraper bridge), make sure there is sufficient distance from the SONATAX sc to the tank edge. - Page 16 Installation If no measurement location without disruptive reflexes can be found, select the probe menu SENSOR SETUP > CALIBRATE and trigger a measurement in the PROFILE LIST menu item. • If there are increased values at the depth of the disruptive reflexes in the PROFILE LIST which influence the measurement value, another measurement location must be selected.
- Page 17 In the determination of a suitable measurement location, the optionally available SLUDGE DOCTOR diagnostic software can be helpful (refer to 7.2 Accessories on page 31). The software enables the representation and saving of all graphic profiles of the SONATAX sc in a defined time interval (5 minutes–2 hours).

Installation The software also shows and saves all important measurement and configuration parameters, such as the reflex list, measurement values, limit values and all advanced settings, such as response time, frequency, amplitude, angle and temperature. Take further information from the SLUDGE DOCTOR user manual DOC013.98.90411. - Page 19 Installation Example 1: Pre-thickener with clear separation layer, but sporadically empty. The image shows a thickener with a clear profile. The signals above the sludge level caused by turbid water do not disrupt the measurement. The same thickener is empty in this image. The threshold now adjusts itself automatically to the signals of the turbid water.
- Page 20 Installation Very low to absolutely no interference signals through turbid water above the separation layer. Strength of the maximum echo <0.3. Instead of the correct measurement value, only the tank floor is found. Increase the adjustment of the ADV. SETTINGS > LL THRESH. AUTO setting from 0.3 to 0.1.
- Page 21 Installation Example 4: Application with large tank depth and clear separation layer, but high absorption of the ultrasound by turbid materials above the separation layer. Absorption is so high that no sludge level is detected at a plunger depth of 0.2 m and LL THRESH. AUTO 0.1 (SENSOR MEASURE error message).

Section 5 Maintenance D A N G E R Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the document. No components that can be serviced by the user are in the inside of the probe. Opening of the probe by the user leads to the loss of the manufacturer guarantee and may cause malfunctions. -
