Abstract

THE PRESENT INVENTION PROVIDES A DEVICE FOR MEASURING THE FLOW OF FLUID THROUGH A CLOSED PASSAGE, THE DEVICE HAVING AN INLET (2H), AN OUTLET (2K) AND A FIRST CHAMBER (2M) IN FLUID COMMUNICATION WITH THE INLET (2H) AND THE OUTLET (2K), THE FIRST CHAMBER (2M) HAVING AN IMPELLER (2E) THEREWITHIN CONFIGURED SUCH THAT FLUID FLOW THROUGH THE FIRST CHAMBER (2M) CAUSES THE IMPELLER (2E) TO ROTATE, THE DEVICE ALSO HAVING A SECOND CHAMBER (2J) HAVING A FLOW MEASURING MEANS THEREIN, AND HAVING A TRANSFER MEANS CONFIGURED SO AS TO BE CAPABLE OF TRANSFERRING ROTATIONAL MOVEMENT OF THE IMPELLER (2E) TO THE FLOW MEASURING MEANS FOR MEASUREMENT OF THE FLOW, WHEREIN THE FIRST CHAMBER (2M) IS SEALED FROM THE SECOND CHAMBER (21) TO PREVENT PASSAGE OF FLUID FROM THE FIRST CHAMBER (2M) TO THE SECOND CHAMBER (2J), AND WHEREIN THE IMPELLER (2E) IS CHARACTERIZED IN THAT IT INCLUDES A CYLINDRICAL BODY WITH TWO OPEN ENDS SUCH THAT FLUID FLOWING THROUGH THE FIRST CHAMBER (2M) FLOWS INTO THE CYLINDRICAL BODY THROUGH ONE OPEN END AND OUT OF THE CYLINDRICAL BODY THROUGH THE OTHER OPEN END, THE IMPELLER (2E) FURTHER INCLUDING A DIVIDER (5E) SEPARATING THE OPEN ENDS WITH APERTURES (5C) EXTENDING THERETHROUGH FOR ENABLING THE FLUID TO FLOW BETWEEN THE OPEN ENDS OF THE CYLINDRICAL BODY AND TO CAUSE THE IMPELLER (2E) TO ROTATE ABOUT AN AXIS SUBSTANTIALLY PARALLEL TO THE DIRECTION OF THE FLOW OF FLUID BETWEEN THE TWO OPEN ENDS.
