6.7.7 Application: Float offset calculation
If the device has the float option, the manufacturer uses data supplied in the customer order to
enter the device settings. If the data (product density etc.) are correct, the device will measure
level correctly. If the data is incorrect, the float offset value in the Basic parameters
Basic parameters
Basic parameters
Basic parameters menu of the
DTM is incorrect. If the float offset value is incorrect, this can have an effect on the performance
of the device.
If the device does not measure level correctly, use the DTM to calculate the new float offset
value. Do the procedure that follows.
•
Go to Application > Float offset calculation
Application > Float offset calculation
Application > Float offset calculation
Application > Float offset calculation.
•
Push the >>
>>
>>
>> button at the bottom of the window.
•
Make a selection from the float types (Ti L=472, Ti L=292 or 316L L=297).
•
Enter the density of the product in the bypass chamber. Make sure that the density of the
product agrees with the density range of the float. For more data about the density ranges for
the floats, refer to the table below.
•
Push the >>

The DTM calculates the float offset and shows the value on the window.
•
Push the >>
