Continuous and reliable
Unaffected by temperature, pressure and
individual gas atmospheres, VEGAPULS
radar sensors are used for quick and reliable
continuous level measurement of various
products.
VEGAPULS 40 sensors enable level meas-
urement with radar in facilities where previ-
ously, due to high cost, it was completely out
of the question.
