The control unit changes the outlet-side flow rate between first and second flow rates, obtains a first pressure, which is a detection value of the pressure sensor when the outlet-side flow rate is the first flow rate, and a second pressure, which is a detection value of the pressure sensor when the outlet-side flow rate is the second flow rate, and estimates an inlet-side pressure of the pressure reducing valve using the relationship among the first flow rate, the second flow rate, and the difference between the first and second pressures."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Gas supply system and method for estimating infernal pressure of gas tank","description":"A gas supply system includes: a gas tank; an unbalanced pressure reducing valve that reduces a pressure of the gas supplied from the gas tank; a pressure sensor that detects an outlet-side pressure of","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11306874","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
