Model: KDS/BGK-Heinrichs-Variable Area Flow Meter

Model KDS BGK Variable Area Flow Meter-Heinrichs

KDS/BGK variable area flowmeter series is indicator housing. The aluminum indicator housing is made of high-performance aluminum and is safely protected from corrosion or weather influences through a special anodizing as well as highly resistant paint finish.

The enclosure surfaces are rounded, the radius is optimized, and protect very effective that splash or other corrosives from the process environment will collect on or at the enclosure. The indicator housing inside has been optimized and therefore turned out to be flatter than it´s predecessor.

The proven technology of the sensor as well as from the sensor transmission has not been modified and will, therefore, be available unchanged with reliability and high robustness.


  • Measuring the volume flow rate of extremely low flow rates of liquids and gases
  • Can be used in the chemical industry or in medical or laboratory engineering
