Page 5: Safety Notes
Safety notes Each person that is engaged with inauguration and operation of this device, must have read and understood this technical manual and especially the safety notes. Installation, electrical connection, inauguration and operation of the device must be made by a qualified employee according to the informations in this technical manual and the relevant standards and rules. -
Page 6: Installation Notes
Installation The correct function of the device within the specific technical data can only be guaranteed, if the permitted process and environmental temperatures (see chapter „Technical data“) will not be exceeded. Installation notes Drive the system pressure free prior installation resp. deinstallation of the sensor.

Page 7: Nozzle Installation
Nozzle installation Use a pipe nozzle if you cannot maintain the blocking distance in any other way. The interior of the nozzle must be smooth and may not contain any edges or welded joints. In particular, there should be no burr on the inside of the tank side nozzle end. Note the specified limits for nozzle diameter and length. -
Page 8: Installation Place
Installation place Level measurement Do not install the sensor in the middle of the tank (C). We recommend leaving a distance • between the sensor and the tank wall (A) measuring 1/6 of the tank diameter. In vessels with conical bottom it can be advantageous to mount the sensor in the center of the vessel, as measurement is then possible down to the lowest point of the vessel bottom. - Page 9 Installation in narrow shafts In narrow shafts with strong interference echoes, we recommend using a stand pipe resp. an ultrasound guide pipe (e.g. PE or PVC wastewater pipe) with a minimum diameter of 100 mm. Make sure that the pipe is not soiled by accumulated dirt. If necessary, clean the pipe at regular intervals.

Page 10: Electrical Connection
Electrical connection The electrical connection of the device must be carried out according to the respective country specific standards. Incorrect installation or adjustment could cause applicationally conditioned risks. Potential equalization - earthing The device must be grounded. The metallic parts of the device are electrically connected with the socket of the plug M12. Connection cable Use only shielded signal and measurement wires and install these wires separated from power leading wires. -
Page 11: Switch Output
Signal 0…10 V A load resistor, e.g. the measuring shunt of an evaluation device, requires at a definitive output voltage an output current. Due to the limitation of that output current, it results in a minimum value for this resistor, where a correct function is still possible. This resistor can be calculated by the following term: / 3mA Lmin... -
