Abstract
A system and method for monitoring a dispensed fluid jet with an oscillation nozzle, comprising a main channel and at least one secondary channel surrounding the main channel, wherein the nozzle has an inlet and an outlet for an air flow defining a flow axis running centrally through the main channel, characterized in that the secondary channel comprises a drill hole.

An oscillation nozzle, comprising a main channel and at least one secondary channel surrounding the main channel, wherein the nozzle has an inlet and an outlet for an air flow defining a flow axis running centrally through the main channel, characterized in that the secondary channel comprises a drill hole.
A system comprising:
- an oscillation nozzle, comprising a main channel and at least one secondary channel surrounding the main channel, wherein the nozzle has an inlet and an outlet for a fluid defining a flow axis running centrally through the main channel, characterized in that the secondary channel comprises a drill hole;
- and
- a sensor for sensing the oscillation frequency.
A method for monitoring a dispensed fluid jet, comprising the steps of:
- a. providing an oscillating flow by injecting a constant air flow in an oscillation nozzle comprising a main channel and at least one secondary channel surrounding the main channel, wherein the nozzle has an inlet and an outlet for an air flow defining a flow axis running centrally through the main channel, wherein the secondary channel comprises a drill hole;
- b. determining an oscillation frequency of the air flow;
- c. injecting a fluid jet and in parallel monitoring frequency, amplitude and phase of the air flow;
- d. determining the time of the fluid jet for passing the oscillation nozzle;
- and
- e. calculating the fluid volume from the determined passing time and known fluid flow rates.
