Managing flow measurement in high-temperature processes poses significant challenges, often leading to equipment failure and inaccurate readings.
Vortex flow meters can handle process temperatures up to 400°C (752°F) with standard sensors, while special high-temperature versions can measure flows at temperatures reaching 800°C (1472°F).
