Over-Inflation of Surfacing Bladders?

[Kim Sleep]

Is over-filling of surfacing bladders ever a problem??
. Ive seen a few microswitch systems used in some cramped spaces. I came up with a solid-state system for my Seawolf that only requires a servo-level start pulse, and automatically fills the BP Cuff to a pre-set amount
Another pulse automatically empties the cuff.

Is this truly a problem or overkill?

Ive also incorporated a failsafe that pumps all the water out if no signals are received after 20 second...as a failsafe

In one system I know of, the bladder is not as robust as a blood pressure cuff bladder and the bladder is in the same wtc as the motors and electronics. Seems like good insurance.
