ABSTRACT:
A system for detecting changes in the electrical conductivity or capacitance of a fluid occasioned by the passage of a follower element is disclosed which includes a hollow fluid passage such as a flowmeter through which a fluid is caused to pass and is provided with at least one follower element of similar cross sectional shape to that of the passage and of a size slightly smaller than the passage which is free to move along the passage and has electrical conductance or capacitance properties substantially different from the fluid. At least one electrically-conductive sensor is disposed in the passage in electrical communication with the fluid. A detector circuit is utilized to sense changes in conductance or capacitance through said fluid in accordance with the presence of said follower element in the conductive path.
