FLUXUS uses ultrasonic waves to measure flow non-intrusively. Clamp-on sensors are simply installed on the outer wall of the pipe. Therefore, there is no wear or damage caused by the measurement object in the pipe, and there is no risk of liquid or gas leakage or pressure loss. And above all, it has the advantage of being able to be installed and maintained while the plant is running without stopping the process.

FLUXUS Clamp-On Ultrasound System

FLUXUS clamp-on ultrasonic systems measure volumetric flow by time-of-delivery methods. Since the ultrasonic signal propagating inside the pipe is transmitted by the fluid flowing inside the pipe, there is a time difference between when it propagates in the same direction as the fluid flow and when it propagates in the opposite direction to the fluid flow. This time difference can be measured very accurately, and the measuring transmitter calculates the volumetric flow value based on the parameters of the pipe structure and the physical properties of the workpiece stored in the database.
