Abstract
Disclosed herein is an approach that uses a wattmeter to obtain diagnostics of a hydraulic system during transient-state start-up operation. In one aspect, a controller uses the electric power measured by the wattmeter during the transient-state start-up operation to determine fluid flow parameters. In another aspect, the controller determines diagnostics for the hydraulic fluid consuming device and the hydraulic pump unit as a function of the fluid flow parameters.
