I n practice it was shown that a pressure of approx. 0.2 … 1 bar is
enough to provide a sufficient air flow (see diaphragm in chapter
"
Technical data").
L arge material heaps are detected with several sensors, which can be
mounted on e.g. traverse cranes. For this type of application, it is best
to orient the sensor toward the solid surface. A mutual infuence of the
sensors is not possible.

eep in mind that for these applications, the sensors are designed for
relatively slow level changes. When using VEGAPULS 68 on a
movable bracket, the max. measuring rate must be observed (see
chapter "Technical data").
