Programmable cartridge-style hydraulic flow sensor

A cartridge hydraulic flow sensor comprising:

• a cylindrical casing comprising an exterior, an interior, an outlet section, and a base, said casing having a first port and a second port through said casing, said first port and said second port permitting a fluid to flow into said interior and out of said interior, said first port being proximate to said base and said second port being in said outlet section;
• a Hall Effect Sensor disposed in said interior, said Hall Effect Sensor being proximate to said second port, said Hall Effect Sensor detecting a number of revolutions of a rotatable impeller rotating about a shaft during a period of time;
• said rotatable impeller being engaged to a shaft support having said shaft, said impeller revolving about said shaft following contact with said flow of said fluid;
• and
• a cover having a communication connector, said communication connector being in communication with a circuit board, said circuit board being in communication with said Hall Effect Sensor,
• wherein said Hall Effect Sensor communicates to said circuit board said detected number of revolutions of said impeller about said shaft during said period of time, said circuit board being constructed and arranged to compare said detected number of revolutions of said impeller about said shaft during said period of time to data stored on said circuit board, said circuit board communicating to said communication connector at least one of said detected number of revolutions of said impeller about said shaft during said period of time, said detected number of revolutions of said impeller about said shaft during said period of time exceeding said data, and said detected number of revolutions of said impeller about said shaft during said period of time being less than said data,
• and further wherein said cylindrical casing is constructed and arranged for insertion into a cavity of a manifold, said cavity being in fluid flow communication with a manifold conduit, a head being proximate to a manifold exterior and said base being disposed in a manifold interior, said first port and said second port being in fluid flow communication with said manifold conduit.
