Installation instructions
Look at the construction drawing of the basin for a suitable position for the sensor. In doing so, you
must take the following factors into account:
• The minimum distance between the basin wall and the sensor is 45 cm (1.48 ft.) (sensor emits
ultrasound in conical form).
• There should not be any basin wall protrusions or piping in the measuring range below the sensor.
Scrapers that are only temporarily in this area are permitted.
• Do not install the sensor in zones in which air bubbles, turbulence, high levels of turbid material
or suspended matter or foam formation occur (e.g. inlet).
• Using an immersion tube, install the sensor 20 cm ( 0.66 ft.) beneath the surface of the water.
• The transmitter may not be installed in a second enclosure (heat accumulation).
• If possible, do not install the transmitter near high voltage sources. In addition, also avoid sources
of magnetic fields, e.g. large transformers or frequency converters.
• The system can only detect a separation zone if there is a clear transition between the zones.
Unclear transition from the liquid to the solid phase cannot be detected.
