ABSTRACT:
Embodiments disclosed herein provide restrictive-flow flow measurement devices, valve improvements and signal control devices and processes that control the flow of liquids, including control processes for single-liquid calibration. In some embodiments, a valve can be adjusted by application of fuzzy logic which involves quantizing input variables into the degree to which a small set of logical values is true. In one embodiment, variables related to flow rate and change in flow rate over time can be compared to membership functions to generate fuzzy inputs, based upon which fuzzy outputs can be generated.
