Abstract
A flow meter apparatus comprising: at least two magnets polarized in substantially opposite directions, mechanically coupled to a mechanical element mounted in a flow conduit and movable by a substance flowing through the flow conduit, for imparting movement from the mechanical element to the magnets, and at least two magnetic field sensors, each of the sensors deployed in a respective position next to the magnets, configured to sense a direction of a magnetic field in the position and to generate a signal indicative of the direction.

A conduit flow meter apparatus comprising:
- at least two magnets polarized in substantially opposite directions, mechanically coupled to a mechanical element mounted in a flow conduit and movable by a substance flowing through the flow conduit, for imparting movement from the mechanical element to said magnets;
- and
- at least two magnetic field sensors, each of said sensors deployed in a respective position next to said magnets, configured to sense a direction of a magnetic field in said position and to generate a signal indicative of said direction.
A method for conduit flow metering, comprising the steps of:
- a) installing at least two magnets polarized in substantially opposite directions in a flow conduit, by mechanically coupling said magnets to a mechanical element mounted in the flow conduit and movable by a substance flowing through the flow conduit, for imparting movement from said mechanical element to said magnets;
- b) deploying at least two magnetic field sensors, each sensor being deployed in a respective position next to said magnets;
- and
- c) sensing a direction of a magnetic field in each of the positions, using the sensor deployed in the position.
A conduit flow meter kit, comprising:
- a processor, configured to communicate with at least two magnetic field sensors and calculate a parameter characterizing flowing of a substance through a flow conduit, using changes in a signal generated by each respective one of the sensors, the signal being indicative of a direction of a magnetic field in position of the sensor, the magnetic field being produced by at least two magnets polarized in substantially opposite directions and mechanically coupled to a mechanical element mounted in the flow conduit and movable by the substance flowing through the flow conduit, for imparting movement from the mechanical element to the magnets.
