4.4 Positioning the SEBAPuls
Formula to calculate minimum distance to wall/shore/etc.
w= tan α*b
α = radiation angle
b = measuring range
w = radiation radius (minimum distance to wall/shore/etc.

Important notice
Pay attention to the vertical installation of the sensor shaft to the measuring medium because
otherwise the echoes are reflected into wrong directions and cannot be received by the
antenna.
