Minimum measuring distance
The minimum distance the radar can measure depends on the antenna selected. Typically the level can
come as close as 0.79 in. (20 mm) from the antenna tip, before the software disregards the signal. Being
this close to the antenna may however reduce the measurement accuracy.
the value Hold Off Distance, which is the default setting for this minimum distance. It can not be
decreased, only increased if needed.
a
Oil, gasoline and other hydrocarbons, petrochemicals (dielectric constant,
r
=1.9-4.0)
b
Alcohols, concentrated acids, organic solvents, oil/water mixtures and acetone (
r
=4.0-10)
c
Conductive liquids, e.g. water based solutions, dilute acids, and alkalis (

> 10)
