Sensor Height (A):
Height of the transmitter's Reference Plane above some user-defined fixed bottom
reference plane. This fixed bottom reference plane should be a location from which
accurate measurements to the reference Plane can be obtained. It may be the bottom of
the vessel but it may also be the ground or other convenient location and does not
necessarily have to be the plane that represents a level of 0.0.
Level Offset (C):
The distance between the fixed bottom reference plane and the plane that represents a
level of 0.0. This offset may be positive (upward), negative (downward) or zero if it
coincides with the bottom reference plane. This offset defines the zero point for the
transmitter's level measurements.
Maximum Product Level (B):
The maximum level reading, in length units, above the Level Offset point that is expected
when the tank is considered full. This parameter is used primarily to allow the level to be
reported in units of % as well as in the specified length units.
