Flow Pulse® Pulsar Non-invasive Clamp-on Flow Sensor

Flow Pulse® is a unique, non-invasive flow sensor that clamps to the outside of a pipe and is simply secured with a screwdriver.

Flow Pulse offers you exceptional repeatability at a fraction of the cost of an equivalent mag flow meter. It can reliably monitor flow across a variety of pipe materials including rigid plastic, stainless steel, cast iron, and even corrugated pipes.

The Technology Within Flow Pulse :

Flow Pulse fires ultrasound through the pipe wall at 90 degrees to the flow via a tangentially mounted high-output ceramic. Ultrasound is refracted at angles across the axis of the flow and is then reflected from bubbles, particles and vortices in all directions and at a wide range of frequencies.

The returned signal is analyzed using Flow Pulse's Refracted Spread Spectrum Analysis (RSSA) digital signal processing platform to derive flow information. RSSA analyses and integrates the received signals over a wide frequency range then slices them for real-time analysis and flow rate calculation.
