The High Pressure Flow Indicating Switch devise and method is used to monitor the flow of a gaseous, liquid or finely divided solid material through pipes, tubing or equipment. This devise is an improvement over technology available at the present time due to its accuracy over an extremely wide range of pressure/flow, simplicity of operation and low cost to manufacture. This High Pressure Flow Indicating Switch is primarily comprised of a pressure confining cylinder housing through which a magnetic field can pass with minimal distortion, a piston containing a magnetic source which emits a magnetic field and a reed/proximity switch mounted to the exterior of the pressure cylinder housing which monitors the position of the magnetic field. As a liquid or gas passes through the cylinder housing, the piston with its magnetic field is displaced and moves in the direction of the material flow. Electrical contacts within the reed/proximity switch are activated by the subsequent magnetic field alignment thus indicating a “Flow” or “No Flow” condition. |
