ThermaFlow 700

Unprecedented capabilities in the world’s harshest environments

Work Hotter and Smarter

Monitor Single-Phase Flows at up to 700°C

The ThermaFlow 700 is the only smart flow sensor that can withstand temperatures of up to 700°C in a single easy to install package. This thermal mass flowmeter features a state-of-the-art, high-temperature design that stands out with its ability to operate in extremely corrosive environments. This sensor can quantify coolant flow, as well as indicate off-nominal conditions such as no-flow or dry pipe.

High Temperature

Excellent performance at temperatures of up to 700°C

Corrosive Environments

Engineered for direct immersion in molten salts and other harsh environments


One sensor, one system, one penetration, in-situ operation
