Clamp-on ultrasonic flow meters can measure high-temperature liquids, but it depends on the sensor type and working temperature range.
The standard normal-temperature sensors are only suitable for liquid temperature from -35℃ to 85℃.
They cannot be used for high-temperature media, because high heat will dry out the coupling gel, weaken the ultrasonic signal, and damage the transducer chip.
For higher temperature applications, high-temperature dedicated transducers are required, together with high-temperature resistant couplant. The high-temperature model can work stably at medium temperatures up to 200℃.
Suitable high-temperature media include hot boiler water, thermal oil, hot process water and high-temperature edible oil.
