The linearization function of the Prosonic M allows conversion of the measured value
into any unit of length or volume. In open channels or measuring weirs, it is also
possible to linearize the flow. Linearization tables for calculating volume in horizontal
cylindrical tanks are preprogrammed. You can also enter any number of other tables
containing up to 32 value pairs either manually or semi-automatically (by filling the
vessel under controlled conditions). You can use the ToF Tool operating program to
calculate the table automatically for any tank form and then enter it into the device.

Terminal compartment
In the F 12 housing, the terminals are located underneath the housing cover. In the
T 12 housing, they are under the cover of the separate terminal compartment.
• For the Foundation Fieldbus version, a 7/8” plug connector is available.
• For the Profibus-PA version, an M12 plug connector is available
Both versions are supplied fully wired.
