Disclosed herein is an approach that uses a wattmeter (150) to determine hydraulic fluid parameters. In one aspect, a controller (155) uses the electric power measured by the wattmeter (150) to determine the power delivered to hydraulic fluid delivered by a hydraulic pump unit (105) to a hydraulic fluid consuming device (200) and the volumetric flow rate of the hydraulic fluid delivered to the hydraulic fluid consuming device (200) by the hydraulic pump unit (105). |
