mobile acoustic flow meter
The AquaProfiler® is a line of acoustic doppler velocimeter flow meters for permanently installed and portable applications. The AquaProfiler® precisely measures water velocities in open channels and pipes. With its high accuracy and competitive cost, the AquaProfiler® is a perfect choice for long-term real-time monitoring or to obtain instantaneous measurements where time savings are an important aspect. It uses advanced Doppler technology to establish the velocity in many separate space points (cells) along the measurement axis and develop the flow profile.

The AquaProfiler® M is a high-precision point-velocity meter. It use a complex pulse-to-pulse coherent sampling scheme that gives the instrument high precision in measurement of velocity within a very small volume a few centimeters in front of the sensor. The small sampling volume provides velocity data that can be considered as point velocities.
The advantages over mechanical meters include: no moving parts, thus less maintenance required, minimal flow disturbance, velocity measurements as low as 0,005 m/s and minimum operating depth of 2 cm.
