Many industrial processes face measurement challenges with high-temperature fluids, leading to costly errors and equipment damage.
Ultrasonic flow meters typically operate reliably from -40°C to 200°C with standard transducers, while special high-temperature versions can handle up to 600°C with proper installation.
