Frank, Overpressure can be blown
of by a overpressure valve (large diameter) or just a valve to equalize
pressure on the surface. Compressor not needed. We had a problem with the
peppers due to a hidden air leak which caused 300 Mbar overpressure in the
small boat!. A barometric instrument
from -100 to +100 Mbar ( 0,1 Atm) will tell some about what is happening
with the sub’s atmosphere. In my opinion it is not
needed to release air in case of flooding for escape. You yust need a large
flood valve which can flood the sub in one minute Regards, Van: owner- Thanks to all for the good thread. Would an amp meter on each motor circuit
be any use? I thought it may give me a heads up if one motor was different than
the others and needed attention. On the internal pressure thing, I had
planned on using a simple manometer like I used when working doing air balance.
It's a tube that shows water column. I was going to modify one by plugging one
end with a valve, and setting it at atmospheric when the hatch is open. With
the valve closed, I should be able to tell if the internal pressure
changes ( up or down ) and adjust accordingly. I'm installing a small
tube/valve on the hatch to release internal air in case I need to flood the sub
for escape, so I can dump the last bubble before opening the hatch. I haven't
figured out how to reduce the internal pressure while still submerged but
thought maybe a small air compressor blowing into a tank would work. Then when
I get close to the surface, dump the tank. Frank D.
