Density Measurement

Density MeasureOur density measuring systems work absolutely non-contacting and non-intrusive. The measurement can be carried out on all liquids and bulk materials, including highly acidic, alkali or saline solutions and suspensions. Clamped on the outer wall of the pipeline, chute or vessel the system components do not come into contact with the measured material and are therefore not exposed to wear and tear. You will get process insight from the outside.

All our density gauges provide a maintenance-free operation and can be easily installed on existing pipelines without process down time. The measurement systems are adaptable to all pipelines from 25 to 1000mm.

 Measuring Principle

 Based on the radiometric principle, our density gauges can be operated in the most demanding and hostile of process conditions. Learn more about our density systems


Technology Highlights

DetectorStabilityDetector Stability

The patented method for detector stabilization ensures a consistent measurement performance, reliably compensating temperature and aging effects.




Our high-sensitive detectors achieve a better measuring effect and can work with remarkably low source activities.
