Probe Length
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
D-3 on page
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
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.
Inner diameter, pipe/chamber/nozzle
Select the inner diameter for the pipe, chamber or nozzle in which the probe is mounted.
