Radiometric sensor VEGA MT31

Type MT31

Radiometric sensor for density measurement


Application Area

The point detector determines the density of liquids and bulk solids from the outside without contact. The sensor is used on vessels of any geometry and on pipelines.
The radiometric sensor for density measurement VEGA MT31 is a radiation-based sensor for non-contact density measurement of liquids and bulk solids. The Minitrac 31 determines the density in a non-contact fashion. It is mounted external to the pipeline or vessel walls. Through its compact design it is ideal for mounting in hard to access positions and in locations with space restrictions.
