1. A process pulsation diagnostic system comprising:

  • a primary element for generating a differential pressure along a fluid flow;

    a sensor for sampling the differential pressure; and

    a processor for generating a pulsation diagnostic based on a standard deviation of the differential pressure, such that the pulsation diagnostic is indicative of a degree of process pulsation in the fluid flow.
