Units of the pressure transducer block

In the pressure transducer block you have the option of setting units in four different places.
Depending on the measurement type, units are allowed from the following measurement
functions:

Description
This parameter specifies the flow point as a % at
which the differential pressure is set in a linear
relationship to the flow.
This parameter specifies the flow point as a %
below which the flow becomes 0.
