Radio Frequency Mass Gauge Analysis Software (RFMG-AS)

About this technology

Overview

The Radio Frequency Mass Gauge (RFMG) is a propellant gauging technique developed for gauging cryogenic propellants in low gravity and normal settled environments. This New Technology Report is for the RFMG-AS, a MATLAB-based software suite with a graphical user interface (GUI) that allows processing of swept-frequency antenna responses to accurately predict propellant tank fuel levels. It is comprised of three main functional components: peak detection, mass gauging, and analysis. Mass gauging is performed by matching experimental peak spectra against simulated peak spectra (eigenmodes) for different tank fluid configurations and fill levels. The RFMG technology was previously disclosed under LEW-18373-1
