Sensor Connection:
Read-only parameter indicating how the Sensor Housing and Process Connector are connected
together. In most cases these two components are connected end-to-end in the Direct mount
mode. For harsh environments where the temperature at the Process Connector is too high for the
electronics inside the Sensor Housing, a 3m Remote Mount cable is available to physically
separate the electronics from the process connector. When the Remote mount mode is used, the
transmitter will acquire a longer echo curve to cover the additional length of the Remote Mount
cable, and will use the process connector reflection as the datum point to find the transmitter's
Reference Plane location.
Mounting Location:
This parameter allows users to select the option that best describes how the GWR transmitter is
located on the tank. The available selections are:

Tank (Mounted to a flat surface in the tank ceiling or wall)

Bracket (Mounted to a bracket over an open roof tank)

Nozzle (See transmitter specifications for limits on nozzle dimensions)

Bypass (See transmitter specifications for limits on bypass dimensions)

Stillwell (Stillwell must extend beyond the length of the probe)

Unknown (To be used only if none of the above are applicable)
Selecting the Bypass or Stillwell options require an additional parameter entry to specify the
inside diameter of the bypass or stillwell. Selecting the Nozzle option requires two additional
parameter entries to specify both the inside diameter and length of the nozzle, as shown in Figure
16.
Mounting Angle:
The physical angle at which the probe is mounted relative to vertical (0 degrees means the probe
is perfectly vertical).
Full Tank Detection:
Full tank detection enables the detection of a level within the upper blocking distance at startup
and it ensures reliable measurement when the block distance high (BDH) is reduced below the
transition upper distance.
This feature enables the transmitter to perform additional analysis on the data in the region near
the reference plane where the product reflections become mixed with reflections from the physical
mounting components such as a flange or nozzle. This additional analysis allows the transmitter to
detect the presence of product in this region even if the shape of the product reflections deviate
significantly from the expected shape. This option should only be enabled if a recently captured
Field or Obstacle background is in use (see below) and the Dielectric Constant of the Upper
Product is above 12. It should not be enabled for products with low Dielectric Constants or when
the Factory background type is being used.
In a demanding application where measurements close to the process connector are required but
large temperature fluctuations are expected it is also recommended to enable Dynamic
Background updates as discussed below.
