A 3d printed scale model of an in line gas flow sensor device.
I have no idea what this is, but I want one.
What is this a part of?
It is a 1/4 scale model of a sensor array that can be used in piping where a gas is flowing. The blue honeycomb straightens the flow of the gas that is to be measured to reduce turbulence. The orange/red part is acts like a funnel to concentrate the straightened flow. The spider part with ribs coming from a central axis has two sets of 4 sensors that measure two different things. They are connected to the outside where the nipples are.
So…is this to do with oil refinery stuff? Sewer stuff?
refinery and pipeline stuff.
The balance between velocity and static pressure i9n a calibrated venturii section eh? Sure beats using a 5 foot Pitot tube inserted into a 4 meter diameter, 500 horsepower mining fan. and safer.
Could this be used in a rocket?
Kenneth, yes, that is pretty much what it is. The guy that did it has a patent, this is a model for him so he does not have to lug around a heavy steel version.
Rene, everything except the sensor array in the middle was done in PLA on a Makerbot Replicator. The array had to be sent out to Shapeways due to its very small size. I gave up trying to do it on a makerbot and formlabs printers.
Wyatt…in a rocket? Maybe if it was not in the exhaust.
I doubt in a rocket. This device woiuld be for precision flow measurements of gases. Rockets use cryogenic liquids yes?
Yeah, so this is ONLY for gas. It could never be used for liquid, right?
This design with that blue lattice is for gases.
Liquids have other forms. In a pipe for one, you can put in a disc with a sharp edged orifice calibrated to the fluid type, pipe size, flow regimes, etc. Then static pressure drop across the opening can relate to flow rate. In an ditch flow depth through a V-shaped notch in a specific shaped section of lined ditch related to volume. Basic Engineering.
Alright, thanks. That clears up things a lot.
