  • High resolution pulse count interface
    Publication number: 20050120806
    Abstract: A high resolution pulse count interface is situated between a positive displacement (PD) meter and a flow computer. A magnetic wheel attaches to the PD meter, with the interface using Hall Effect sensors to detect the rotation of the wheel. A pulse prediction algorithm and weighting algorithms are used to improve resolution for the flow computer to enable real time flow rate calculations.
