Gas valve with fuel rate monitor

A valve assembly, comprising:

• a valve body having a valve port and a valve sealing member axially translatable within the valve port;
• a valve controller affixed to the valve body, the valve controller is configured to monitor a differential pressure across the valve port;
• the valve controller is configured to monitor an axial position of the valve sealing member within the valve port;
• the valve controller is further configured to determine and monitor a flow rate of fluid passing through the valve port, where the valve controller determines the flow rate based, at least in part, on the monitored differential pressure and the monitored axial position of the valve sealing member;
• and
• the valve controller configured to output the flow rate.

A gas valve assembly for controlling a gas flow to a combustion appliance, the gas valve assembly comprising:

• a valve body having an inlet port and an outlet port, with a fluid path extending between the inlet port and the outlet port;
• a gas valve member situated in the fluid path between the inlet port to the outlet port, the gas valve member selectively movable between a closed position, which closes the fluid path between the inlet port and the outlet port, and an open position, which opens the fluid path between the inlet port and the outlet port;
• and
• a flow module for sensing one or more parameters of a gas flowing through the fluid path, and determining a measure that is related to a gas flow rate through the fluid path.
