Well in the specifict case of this thread it might not be that easy.
If you perhaps have 2 lpm O2 plus the ordinary "KISS"-flow going into the loop? Thats a little more than 3 times the "usual" KISS-flow. How much will that offset your diluent flush verification? Not speculating on depth, choice of dil, loop volume, rate of dil injection or location of cells vs dil injection I would dare to say chances are it can screw up your dil flush..
Given the relatively small loop volume, you will definitely feel the bouancy change, with your mentioned runaway solenoid, or a cell going down. As the oxyscan governing the solenoid is fixed, you have to compare with the other one which is not branched to the electronics.
And, as you mentioned, either close the oxygen supply, flying manually, or, in a case of a cell running away high, rely on the low flow orifice and oxy flush function.
What I'd like, then, was an option to close down the electronics, or shut it down pneumatically, for instance by independent oygen regs, one for the KISS flow, one for the solenoid.
