Intelligens Flow

Built around an Intelligens WW data logger, flow velocity is measured by a Doppler-effect sensor that uses ultrasonic pulse technology. To generate level, a Piezo resistive probe is fitted, including a
desiccant tube to maintain proper sensor function.

Non-contact level measurement can be achieved using a SonicSens 3 ultrasonic sensor. Software within the unit can automatically be added depending on the nature of the application.


Intelligens Flow is an sophisticated flow monitoring system designed to measure flow in part-filled pipes and open channels.
