XSENS clamp-on flow rate meters can be used for pipeline flow rate and leak detection measurement, replacing the most common inline technologies by clamp-on measurement. Examples of inline technologies provided by other companies are:

  • Turbine velocity flow meter: fluid velocity which spins a wheel
  • Turbine mass flow meter: fluid inertia
  • Magnetic flow meter: electromagnetic induction
  • Ultrasonic flow meter: measuring time of flight of the acoustic signal
  • Coriolis flow meter: fluid inertia, Coriolis effect
  • Positive displacement flow meter: movement of fixed volumes
  • Differential pressure flow meter: fluid mass self-acceleration and the exchange of potential-kinetic energy

Having such a wide array of technology choices can be overwhelming for clients when making decisions on which technology suits their application best.

The XSENS technology for flow rate measurement is based on ultrasonic signals to measure the time of flight. We transmit the signal from outside of the pipe wall. The signal is then steered through the medium close to the inside of the pipe wall and through the center of the pipe. This patented technology allows XSENS to measure the full velocity profile of a medium, which means our measurement takes place across the full diameter of a pipe (full bore measurement).

This provides the XSENS flow rate meters with high accuracy of +/-1% of flow. The benefit of ultrasonic technology is that we can measure flow with a very high turn-down ratio of 1:400, which means we can measure from 0,1 to 40 m/s.

Our meters are clamped to the outside of a pipe. This provides easy installation (typically 2-3 hrs) and reliability as the meter is not in contact with the medium. Therefore, there is no risk for erosion, corrosion, waxing or scaling. Minimal maintenance is required.
