Type C isotope densimeter

Description

The Type C Densimeter enables continuous measurement of the density of substances transported through pipelines, as well as other properties of these substances calculated based on the measured density.

Applications in process control automation systems:

  • Flotation processes
  • Coal enrichment in heavy media
  • Water-slurry circuits
  • Preparation and transport of backfill mixtures

The type C Densimeter offers:

  • A modern design adaptable to the technical conditions of a given facility
  • High operational reliability
  • Maintenance-free measuring sensor
  • FULL OPERATIONAL SAFETY – virtually no restricted access zone, due to the use of a very low-activity isotope (approximately 20 to 30 times lower than in other densitometers)
