Apparatus and method for automatically detecting and alerting of gas-out conditions for a gas appliance during operation

摘要: A gas appliance monitoring apparatus for automatically detecting and alerting to a “gas-out” condition of during operation, and/or the presence prolonged “gas-on” conditions an appliance. The utilizes highly sensitive low loss flow indicator with multiple sensors monitor characteristics use. analyzer alarm timing mechanism analyzes sounds at or wirelessly remote location upon detection either above conditions. biasing attraction magnet is incorporated in fluid offset force gravity return spring flow/low pressure applications. piston sealed use high pressure/low applications, provided vent hole residual bleed-off stoppage flow.
