Evandor

What we measure

One sensing platform, applied across the sealed systems that decide a mission. Fill and slosh in tanks, combustion inside chambers, and flow through feed lines, all read from the outside.

One platform, many geometries

The platform separates hardware, sensor heads and data, so customers integrate without rebuilding. One shared core reads every geometry, from spacecraft tanks to feed lines to combustion chambers.

RING SENSOR HEAD

Spacecraft tanksFill, slosh and gauging

Propellant mass, phase boundaries and slosh in sealed spacecraft tanks, resolved in any gravity. Remaining propellant decides a satellite’s working life; reading it keeps hardware in service longer.

COLLAR SENSOR HEAD

Feed systemsFlow, entrainment and phase

Flow behaviour, gas entrainment and phase in propellant feed lines, read through the pipe wall.

BAND SENSOR HEAD

Combustion chambersImaging and acceptance

Internal combustion imaging over a full firing, from ignition to flameout, for propulsion test and acceptance programmes.

The Vira platform

Core hardware

One shared electronics core drives every sensor head, so a new geometry needs only a new sensor head.

Data layerReconstruction and outputs

The measured field solved into the interior and returned as live numbers and images.

Adjacent markets like liquefied gases and hydrogen are later-stage optionality, not near-term products.

Measurement accuracy

The figures below come from the published ECT record and describe the measurement class, not a qualified Evandor product; they are also definition-sensitive.

<1%
Average mass in a real satellite tank, slosh resolved to within ±0.1%.
Heritage satellite tank programme
0.3–0.9%
Full-tank-mass uncertainty in microgravity gauging.
Parabolic-flight campaign
±0.2%
Bubbled-gas agreement in cryogenic liquid nitrogen.
Cryogenic LN2 test programme

Figures are attributed to their source programmes. Spaceflight work may be export-controlled.
