The oscillation in the circuit is created by applying power to the amplifier (60) which creates an initial fixed standing wave that does not move. Adjusting or changing components, invokes a new behavior of the circuit which is parasitic in nature and reading of oscillating frequency on the frequency reader (70) determines the change of conditions inside the vessel or container. The method is non-intrusive, and the method of this invention can also be used for measurement of miniscule quantities in microns or micro liters such as that of biofilm or algal growth."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for measuring volume of contents of a vessel or pipe using circuit oscillator","description":"A circuit is set up for a container or vessel (10) as shown in FIG. 1, which has a microphone (20), a speaker (30), a frequency control device (40) volume control device (50), an amplifier (60), a fre","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11287302","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.
