Measured variable The measured variable is the distance between the reference point and the product
surface. The level is calculated based on "E", the empty distance entered.
Measuring range The start of the measuring range is the point where the beam hits the floor. Levels below
this point cannot be measured, particularly in the case of conical outlets. An alignment
unit can be used to increase the maximum measuring range in such applications.
Maximum measuring range
The maximum measuring range depends on the antenna size and design.
Antenna Maximum measuring range
Horn, 316L, 65 mm (2.6 in) 125 m (410 ft)
Drip-off, PTFE, 50 mm (2 in) 50 m (164 ft)
Flush mount, PTFE, 80 mm (3 in) 125 m (410 ft)
Usable measuring range
The usable measuring range depends on the antenna size, the medium's reflective
properties, the installation position and any possible interference reflections.
In principle, measurement is possible up to the tip of the antenna.
Depending on the position of the product (angle of repose) and to avoid any material
damage from abrasive media and deposit buildup on the antenna, the end of the
measuring range should be selected 10 mm (0.4 in) before the tip of the antenna.
