Fuel measuring and recording systems for combustion devices and method for monitoring fuel flow

摘要

A fuel measuring and recording system arranged for use with a fuel system for combustion devices of the type which recirculate unburned fuel back to the fuel system. The present system includes a measuring device which measures fuel flow. Recording apparatus is responsive to the measuring device to make a record of fuel flow. Compensating structure can be used in the measuring system to compensate the measurement for variations in the physical characteristics or temperature of the fuel. Structure for treatment of the fuel may be employed with the fuel measuring system. Another concept of the invention conducts fuel from the measuring device to the combustion device in bypassing relation to the structure for treating the fuel. Also comprising a part of the present invention is a method for monitoring fuel flow whereby a measured amount is determined prior to and bypassing a treatment zone which receives excess fuel and whereby the measured amount is recorded.
