Distance measurement
Distance measurement depends on a number of factors, covered in the menu items below:
•
tank height
•
blocking distance
•
reference offset
These will influence the effective measuring range of the device and the point from which measurements
are taken.
Tank height
function C.1.2.0
The height of the tank from the top of the tank process connection facing to the tank bottom. If not indicated
in the order, this is set at the factory to probe length.
Blocking distance
function C.1.9.0
Refer to section 7.1.2: Technical data, blocking distance for the minimum recommended value for a given
probe type. This prevents the device from displaying measurements within this distance to the flange and
avoids confusion with parasite signals near to the flange.
Reference offset
function C.1.10.0
Configure the device to measure the distance to the product surface using a reference point other than the
default flange facing.
Move the reference point above the flange facing by typing in a positive value. Move the reference point
below the flange facing by typing in a negative value.
