1. flow probe comprises:

  • One measuring chamber can be imported therein and discharges a medium again, measure the volume and/or the flow velocity of this medium;

    But the measuring elements of the free rotary ground supporting that in this measuring chamber, is provided with (30,40);

    At least one is in order to measure the sensor (51) of magnetic field and/or changes of magnetic field;

    One conversion equipment (70), this conversion equipment are supplied to the output signal of described sensor (51,52);

    Wherein said sensor (51,52) sends an output signal and also supplies to conversion equipment (70), and this output signal is in an each single-wheel tooth (42) and cyclic fluctuation and have a reproducible intermediate value with respect to the position of described sensor (51,52) according to the gear teeth (42) between a minimum value and maximal value during an affiliated teeth groove by one of them measuring elements (40);

    AndWherein conversion equipment (70) formation makes this conversion equipment be formed the output signal (71,72,73) of oneself by the output signal of described sensor (51,52), described oneself output signal is converted into isarithmic value with intermediate value, the partial volume of the volume that described isarithmic value representative is carried between two gear teeth (42).
