Gas burner for cooking appliances

A method of operating a cooking appliance, comprising:

• receiving a user-defined input signal corresponding to a desired quantity of heat to be delivered by a gas burner to a cooking surface;
• determining a maximum burner air/gas mixture flow rate using a flow sensor comprising a gas flow input in fluid connection with a venturi which is configured to mix air with the gas flow to provide a primary aeration of the gas burner, the flow sensor being configured to measure pressure at the venturi, the flow sensor further comprising a differential pressure sensor configured to measure a pressure differential at the venturi between the maximum burner air/gas mixture flow rate and a user input burner air/gas mixture flow rate that is input by a user as a requested percentage of the maximum burner air/gas mixture flow rate;
• and
• modulating the burner air/gas mixture flow rate to provide a target burner air/gas mixture flow rate based upon the user-defined input signal and the determined maximum burner air/gas mixture flow rate.
