The downstream side valve is disposed downstream of the flow restrictor in a flow path. The downstream side pressure sensor measures a pressure between the flow restrictor and the downstream side valve. The first flow rate calculator calculates a first flow rate of fluid flowing through the flow restrictor. The second flow rate calculator calculates a second flow rate of fluid flowing out of the downstream side valve on the basis of the first flow rate and the temporal variation in downstream side pressure measured by the downstream side pressure sensor. The flow rate controller controls the downstream side valve on the basis of a set flow rate and the second flow rate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Flow rate control apparatus, flow rate control method, and program recording medium","description":"Provided is a flow rate control apparatus that includes a flow restrictor, a downstream side valve, a downstream side pressure sensor, first and second flow rate calculators, and a flow rate controlle","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10545514","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.
