On rockets you have lots of other ultrasonic sources (Engine, incoming
pressurant, airflow around the airframe ect.). I am pretty sure this
interferes with the sensor. Keep also in mind that speed of sound
depends on the root of the temperature of the gas (and that changes
quite during operation in a tank).
What about a looking up sensor arrangement?
the liquids properties should not change all that much.
and it is much easier to get good coupling into a denser fluid
than into gases.
Which leads us by the nose to
a bog standard marine echo sounder ;-?
