• Average angle of every path
• Length of used cable in one sound path
• Roughness inside the pipe
• Viscosity of measured media
Note
Automatic calibration can only be used for ordinary round-shaped pipes.
Note
Always use AUTO calibration mode for flowmeter systems with SONOKIT sensors (menus
7.1.4.x.6 show the automatically calculated calibration factor).
Always use WET calibration mode for flowmeter systems with SONO 3100 or SONO 3300
sensors (menus 7.1.4.x.6 show the calibration factor, and menus 7.1.4.x.7 show the calculated
flow).
App. param. (menu 7.1.2)
In this menu application-specific data can be entered.
Viscosity (menu 7.1.2.1)
The media viscosity value is used for the flow calculation and should only be changed for
SONOKIT
The viscosity is default set to 0.01 cm
2
/s (normal water).
Correct. fact. (menu 7.1.2.2)
This is a parameter that can be used to adjust the calculated flow.
Fl. offset comp. (menu 7.1.2.3)
The flow offset compensation (a constant positive or negative flow) can be added to the
measured flow for service purposes.
Cablelen. TOFKOR (menu 7.1.2.4)
The transmitter is always installed in a remote position. Therefore it is necessary to enter the
length of the sensor cable in order to compensate for the time delay occurring in the cables.
The cable length is the total length of the signal cable in one sound path. The measuring unit of
the cable length is meters. The tolerance is ±0.5 m.
