New Placement:
- Thermocoupler along axial probe
- Pressure sensor connected to tank through tube
- Might receive some varying pressure readings due to collisions from fluid, but will level out
- Useful for comparing pressure readings when collisions happen
- Pressure transducer + impulse line (stainless tube to prevent damage due to temp)
- Non-wetted setup that prevents the collision readings
- Strain gauge transducer, stainless-steel
- Might receive some varying pressure readings due to collisions from fluid, but will level out
- Thermal Cameras on bottom/top
- Constant processing may be excessive for OBC
- Better to have a pressure sensor on the lid of the tank to measure pressure drops.
- If used: Longwave IR camera
- Thermal Cameras placed axially to measure the surface temperature of tank (not verified)
- Since no MLI, can be used to give us a 2D temp field to complement axial thermocouple
- Longwave IR camera
Additional consideration:
- Omit MLI on outside because the top/bottom needs to be affected by the Sun
- We want to have a similar thermal load as the real tank, which has insulation that is not 100% effective.
OBC:
- For constant health checks we will need our own OBC. We need constant updates on the status of the tank for safety and it is unlikely that the satellite we are putting our payload in would want to share that much.
