10 4.6 Vibrations Vibrations of the pipes should be avoided by anchoring the pipe before and after the sensor.

11 4.8 Magnetic fields Strong magnetic fields close to the sensor should be avoided. 4.9 Temperature In open air installations it is recommended to

12 With thermally insulated pipes DO NOT insulate the sensor. High temperatures can damage it. The maximum liquid temperatures are shown on page 51.

13 MOUNTING In order to make the positioning of the insert in the pipe easier, there is a label on one of its sides with markings indicating the posi
