An electric circuit board for operating the solenoid valves is contained within the housing. Also contained within the housing and connected to the electric circuit board are a temperature sensor and a pressure sensor for sensing temperature and pressure in the flow path. An electric-operated temperature control element in thermally conductive contact with the housing controls temperature along at least a portion of the flow path."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Gaseous fluid metering unit","description":"A fluid metering unit has a housing providing a flow path from an inlet port through a first solenoid valve and a second solenoid valve to an outlet port.
