PresMat Barometer not working in oceans?

[seanth]

I was looking at the readings from the PresMat Barometer as a part I had descended into the ocean of Kerbin, and the readings weren't making sense based on the density of water on Kerbin since 1.0.5

 

Sitting at a depth of 513m below the surface, and with a water density of 1000km/m³, I would expect the pressure to be:

Density*gravity*depth=1000kg/m3 * 9.81m/s² * 513m = 5,032.53 kPa

Instead I see a value of 101.325 kPa...which is what I would expect to see for an atmospheric value near sea level.

It seems like the part isn't "seeing" that it's in liquid and is still using the atmospheric density calculation.

This definitely feels like a bug and might make it impossible for sciency players (or the children of players that are being encouraged to play KSP to use applied mathematics) to derive the density of liquids on other planets de novo (which would be cool).

Can anyone else confirm it's not working correctly?

I guess you previously exposed it to air, therefore voiding its warranty. Tough luck!

On a more serious note, what you're expecting is probably just not implemented. Watercraft are a fairly new thing in KSP, and the "S" in KSP still stands for "space" (though "space-subs" sounds even cooler)

What do you expect? That part was programmed to measure atmospheric pressure. This game isn't about exploring oceans. It's just that the water landings became more forgiving, because previous water was broken.

My vague memory was that the part worked correctly back in 0.24 when I was submerging orange tanks. I could just be misremembering, though.
