Patent ID: 7552799

Claim:
A method of controlling the distribution of lubricant in a system of engineering components comprises: measuring the thickness of lubricant on at least one element of the system with lubricant film thickness measuring means, passing a signal corresponding to the thickness measurement to control means, determining a value of at least one physical variable of the lubricant being of relevance to the lubricant film thickness with calibration means, sending the value of the at least one physical variable of the lubricant to the control means, calibrating the thickness measurement with the control means based on the value of the at least one physical variable of the lubricant to obtain a calibrated thickness measurement; determining an amount of lubricant to be supplied to one or more components of the system with the control means, based on the calibrated thickness measurement, and sending control signals to lubricant input means to control a supply of lubricant to the system.
