摘要： A variable orifice flow meter system includes a housing defining a flow passage and at least one plate extending into the flow passage and defining an orifice. The at least one plate is movably supported such that a size of the orifice may be adjusted. Upstream and downstream pressure sensors may measure fluid pressures upstream and downstream of the orifice and a drive mechanism may move the at least one plate. A controller may instruct the drive mechanism to move the at least one the plate such that a predetermined orifice size is defined in response to detecting an upstream pressure within a predetermined pressure range, determine a pressure differential across the orifice and calculate a flow rate through the flow passage based on the pressure differential when the pressure differential meets a predetermined threshold.

摘要： A water heater control system comprising an energy storage system electrically connected to a pilot valve operator and electrically isolated from a main valve operator. The energy storage system may be electrically connected to an ignition circuit. A thermoelectric device is in thermal communication with the pilot flame and electrically connected to a main valve operator. The water heater system may include a microcontroller configured to establish electrical communications between the device and the energy storage system, the pilot valve operator, and the main valve operator. The microcontroller may be configured to recognize a call for main burner operation, and may also be configured to check an available voltage of the energy storage system against a setpoint. The microcontroller may establish pilot flame operation with or without main burner operation, depending on whether a call for heat or recharging of the energy storage system is required.

摘要： A gas valve assembly includes a gas valve and a control circuit. The gas valve is configured for variably controlling a flow of gas through the gas valve assembly. The control circuit includes a controller programmed to determine a first setting for the gas valve in response to a received commanded flow, adjust the first setting to a second setting based on a measured temperature when the measured temperature is one that may induce changes to the flow of gas through the gas valve assembly, and control the gas valve based on the second setting.
