STROKE VOLUME DISPLACEMENT FLOW RATE SENSOR AND METHOD FOR REGULATING FLOW
First Claim
1. A sensor for measuring volumetric flow rate of a fluid, comprising a body comprising an inlet and an outlet and at least one flight tube there between comprising at least one marker detector disposed along said flight tube configured to detect a position of at least one marker in the fluid;
- and a control circuitry for determining the volumetric displacement of the fluid along the flight tube from a first known position of said marker, and at least a second position of the marker detected by said at least one detector.

Abstract
A flow rate sensor comprising a body comprising an inlet and an outlet and a flight-tube interconnecting there between. A plurality of electrodes are disposed along the flight tube. The electrodes are electrically operable to introduce a marker to the fluid at a first position in the form of a local fluid composition variation and to detect the position of the marker at least at a second position downstream of the first position, thereby determining the displacement of a fluid volume in the flight-tube and infer the volumetric flow rate of the fluid at a flow pulse.
