If the beam passes through the pipe at an angle of 90°, this value corresponds to the
internal pipe diameter. If the beam passes through the pipe at an angle of 30° in order to
increase the sensitivity of the measurement, the length of the beam path corresponds to
twice the internal pipe diameter.
The unit of length can be defined in the "Measurement settings" section
Calibration of interface medium 1 / 2
1. The radiation is switched on and the beam path is covered: only with Medium 1 or
only with Medium 2

The calibration can be performed by pressing the "Start interface 1st/2nd
medium calibration" button. The measurement then starts automatically and
continues, at the very maximum, for as long as has been configured for the
calibration time. However, the process can also be stopped manually by pressing
the "Stop calibration" button.
The calibration stops automatically as soon as a million pulses have been
totalized.
Alternatively, the pulse rate can also be entered directly.
For the "Next" button in the Wizard to be enabled, the value must, however, be
changed from the start value, at least temporarily.
2. With this calibration point, the density of the medium is entered in the "Density
calibration value of 1st/2nd medium" field.
 This establishes the reference between the determined pulse rate and the density
of the medium.
The "Calibration date of 1st/2nd medium interface" field provides the user with
information on the time the calibration value was recorded.
