ABSTRACT:
There is provided a counting apparatus which is designed to be located in any position in series with a fluid flow line. The apparatus has a first magnet in an air chamber of the body of the counter. As the fluid passes through the air chamber, the first magnet is forced down the air chamber by the fluid flow. The magnetic field of the first magnet passes through a magnetic field of a second magnet located in the mechanical counter causing the counter to mechanically change the number. When the fluid flow is stopped, a spring returns the first magnet to its original position again passing by the second magnet in the counter allowing the counter to reset for the counting of the next cycle.
