3.4.2 Shorten the probe
In order to leave some clearance distance between the probe end and the tank bottom,
the probe might have to be shortened. The goal is to have the probe hang straight so that
it does not touch the wall; 2 in. (5 cm) is a suggested value. The probe can be shortened in
field. Use the following form to calculate the probe length:
Probe length = tank height - 2 in. (5 cm)
After shortening the probe make sure to update the transmitter configuration to the new
probe length, see
