Configuration Parameters
Figure D-2. Upper Reference Point
Probe Type The transmitter is designed to optimize measurement
performance for each probe type. The transmitter
automatically makes an initial calibration based on the type of
probe that is used. (This parameter is pre-configured at
factory and only needs to be set if the probe is changed to
another type, or if you have installed a spare transmitter)
Select the type of probe that is mounted to the transmitter.
Select User Defined probe if your probe can not be found in
the list or if you have done modifications to a standard probe.
Probe Length The probe length is the distance between the Upper
Reference Point and the end of the probe, see Figure D-1 on
page 160. If a weight is used at the end of the probe it shall be
included.
This parameter is pre-configured at factory. The probe length
must be changed if the probe is shortened, or if you have
ordered a spare transmitter head.
Tank Height The Tank Height is the distance from the Upper Reference
Point to the bottom of the tank (Zero Reference Point). See
Figure D-1 on page 160.
The transmitter measures the distance to the product surface
and subtracts this value from the Tank Height to determine
the level.
When setting the Tank Height, keep in mind that this value is
used for all level measurements performed by the Rosemount
3308 Series Transmitter. The Tank Height must be set in linear
(level) units, such as feet or meters, regardless of primary
variable assignment.
Mounting Type Select option best describing how device is mounted on the
tank.
