Non-Intrusive Flow Measurement at Extreme Temperatures 

Flexim's (Germany) patented WaveInjector clamp-on mounting fixture enables the non-intrusive ultrasonic flow measurement of liquids at extreme pipe wall temperatures ranging from as low as -190 °C up to 400 °C and beyond.

Since the WaveInjector is a purely mechanical solution, it can also be used - in conjunction with FLEXIM’s ATEX, IEC and FM approved transducers and transmitters - within hazardous areas.

Thus, the WaveInjector realises long-time temperature stable, reliable and accurate clamp-on ultrasonic flow measurements at extreme temperatures in combination with the well-known advantages of the clamp-on ultrasonic technology: No process stops for installation combined with a virtually maintenance free measurement.

Typical applications areas where the WaveInjector is employed are found at LNG terminals, Refineries or even molten salt flows at Central Solar Power plants - where pipe wall temperatures easily reach up to 580 °C. Moreover, as the pipe segment, where the WaveInjector is installed, will be reinsulated after installation, there are no thermal energy losses.
