Flexim WaveInjector technology enables metering at extreme temperatures from -328°F up to 1166°F. Using patented technology, the Flexim WaveInjector thermally separates the ultrasonic transducers from the hot or cryogenic pipe, allowing permanent flow measurements at extreme pipe wall temperatures providing the ultimate competitive edge - in process control, process management, and environmental protection. The WaveInjector, along with the ultrasonic transducers, is simply installed on to the outer surface of the pipe, using coupling plates for a proper acoustic contact. This means, that there is no need to open the pipe - no drilling, and no process shut-down is required.
