SONOKIT uses "AUTO" to determine the calibration factors based on input of:
-
-
-
-
-
-
-
Note
Automatic calibration can only be used for ordinary round shape pipes.
Nice to know:
When WET selected is, the calibration parameters will be taken from the factory calibration
process. These parameters will be stored in special WET calibration parameters (eg SONO
3100 and SONO 3300 sensors). In this case the factory predefined data should not be changed.
Note
Please use AUTO calibration mode for all SONOKIT systems. For SONO 3100 and SONO 3300
"Wet" calibration should always be chosen.
Media viscosity, menu 7.1.2.1
7.1.2.1 Viscosity
The viscosity value will be used in the flow constant formula.
The viscosity is default set to 0.01 cm
Correction factor, menu 7.1.2.2
This is a user parameter that can be used to adjust the calculated flow.
Offset compenstation, menu 7.1.2.3
The offset compensation is equal to the addition of a constant flow. This can be used for service
purposes.
Cable length-time of flight, 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 track. The measuring
unit of the cable length is meters. The tolerance is ±0.5 m.
Pipe diameter, menu 7.1.3.1
This value represent the average inside diameter of the actual pipe.
Note
All sensor charachteristics in menus 7.1.3.x are determined and preset at the factory.
They should not to be changed for flow meter systems with sensor types SONO 3100 and
SONO 3300.
For SONOKIT the FUS060 transmitter is preset at the factory according to the
SONOKIT order codes (pipe dimension, number of tracks). The exact sensor pipe
dimension (from the "SONOKIT - SENSOR GEOMETRY MEASUREMENT REPORT")
must be entered.
