Spatialisation of flow metering assemblies for spacecraft thermal control and propellant systems

Fluid loops onboard spacecraft often need one (or more) flow meter(s) to monitor or control the performance of the loop or its components. Typical examples are: -flow meters in single-phase thermal control loops. to control pump speed and valves settings to have the right mass flow rate, hence the right amount of heat collection, transport and rejection; -flow meters in two-phase thermal control systems, to control pump speed and valve settings to optimize system response and stability, in conjunction with vapor quality sensors; -flow meters in propulsion systems to monitor (by bookkeeping) the total quantity of propellant used, thus providing information for the end-of-life determination, to optimize the mission strategy, to decide on satellite replacement, etc.
