Take up the brine challenge … how to apply flowmeters for geothermal brine


Geothermal fluid is basically a multiphase mixture consisting of steam, NCGs and brine which can contain H2S, chlorides and other substances. Once separated the challenges in the brine continue. Temperatures up to 220 °C, high salinity and corrosivity, diffusion and later in the the process even vacuum can occur. Get to know the different challenges and applicable flowmeter principles with its limitations which are explained along with application examples.

Key Takeaways

  • Learn the fundamentals of the geothermal power generation process
  • Understand the challenges geothermal fluid and brine
  • Learn about the applicable principles for flow measurement
  • See some typical examples of how theses systems are applied in the process
