UWB utilizes a radio frequency (RF) technology to enable the accurate measurement of the time-of-flight of a radio signal and UWB positioning can operate in Time-Difference-of-Arrival (TDoA) mode, Two-Way-Ranging (TWR) mode, and Phase-Difference-of-Arrival (PDoA) mode. The systems disclosed herein include multiple anchor devices having a UWB antenna(s) and positioned in fixed location(s) over the fluid to be measured. The anchor devices serve as reference points for UWB communication with a remote float device, which emits RF signals and floats on the surface of the fluid to be measured. The anchor devices may include, or be in communication with, a processor which receives and/or measures RF signals, generates timestamps, calculates distance(s) between the remote float device and an anchor device, calculates fluid level, calculates an angle-of-arrival (AoA), or any combination thereof."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Devices, systems, and methods for measuring fluid level using radio-frequency (RF) localization","description":"Disclosed herein are devices, systems, and methods for accurately determining fluid level using Ultra Wide-Band (UWB) positioning or localization.
