Abstract

Systems and processes for fluid regulation may provide diagnostic information that is useful for evaluating the condition and/or needed repairs/maintenance for fluid regulation systems (100). In particular implementations, a system and process for fluid regulation may include the ability to receive a representation of an input signal to an electric-to-pressure converter (124) for facilitating positioning of a fluid regulator component, the electric-to-pressure converter adapted to be part of a fluid regulation system including a fluid regulator (110) and a fluid regulator controller (120), and to determine at least one fluid regulation system condition based on the converter input signal.
