8 Installation and commissioning
Ultrasonic Probe KNX SO250 • Version: 14.09.2020 • Technical changes and errors excepted.
The measuring head must be dry:
It must not be washed by liquids!
No condensation, no droplet formation!
The measuring track must be free:
No steam, fog, etc. between the sensor and the measuring surface!
Steam is formed e.g. when a warm fluid is poured into a tank.
The measured surface must be still:
No waves, no vibrations!
To avoid wave formation in fluids, the measured area can be separated using a meas -
uring tube (Ø at least 50 mm).
Note: The measuring surface is only quiet as long as the end of the measuring tube is
below the surface.
