  • Page 6: Introduction

    The position at one eighth of the diameter, a position representing the average speed The velocity sensor of the HydrINS 2/HydrINS 2 Mini flow meter can be inserted in different positions across the cross-section of the pipe. This allows a flow velocity profile to be created in order to refine the mean speed calculation and therefore also the flow measurement.

  • Page 7: Measurement Principle

    In the case of HydrINS 2/HydrINS 2 Mini, the magnetic field is generated by a coil at the end of the probe, and the water passing through the pipe, whose conductivity must be at least 20 µS/cm, represents the conductor.
