A renewable energy company that produces and stores green hydrogen had a need for flow switches on their hydrogen generator skids for low flow protection.
Comparing Magnetrol’s revolutionary new multiphase detector with the radiometric gauging approach to level profiling.

Many liquid tanks in the chemical, refining, food & beverage, life sciences and other process industries can, at times, have foam present. The dynamic nature of foam means there is no “one-size-fits-all” measurement solution. In addition to knowing what type of measurement is required, it is also critical to consider the characteristics of the foam itself.
Objective: To identify key areas in the steam generation cycle, condensate recovery system and waste heat recovery process where cost-effective instrumentation solutions offer a tangible return on investment over the short-term. The goal is to reduce heat rate, environmental impact, fuel and water consumption, water treatment and maintenance costs in commercial and heavy industries where steam generation is essential to the production processes.
Interface or multiphase level measurements exist throughout the Oil & Gas streams as well as Petrochemical. While level measurement technologies have come a long way in effectively measuring liquids and solids, multiphase level measurement continues to be the biggest challenge and opportunity that exists today to which there is no perfect technology. However, experience has shown that process optimization and increased uptime can still be achieved in many separator applications through reliable, best-in-class, level technology. The objective of this paper is to review interface challenges, the current technologies being utilized for interface, field experience in various applications to achieve process optimization and increased uptime, and the future of reliable interface measurement.
Thermal dispersion switches use similar measurement principles to thermal mass flow meters. Fluid carries heat away from the probe tip reducing the temperature difference between a heated resistance temperature detector (RTD) and a reference RTD. As the temperature difference increases or decreases due to heat transfer, the set point is reached and the relay de-energizes. Manufacturers will refer to the switch being in “alarm” at set point. How the relay is wired (NC-CO or NO-CO) depends on the needs of the application.
