Frequently Asked Questions
Question 1:
This you say is available for sizes that are too large to make membranes for or for temperatures to great for elastomer membranes - is this device available in small sizes?

Answer:
Generally speaking it is not economical in "small" sizes. As the cushion prefill gas is not absolutely sealed in the chamber above the float the norm is to operate floatolators at least half full of liquid. This keeps the churning action of the liquid away from the liquid/gas interface, therefore, they are always at leat twice the volume you would expect. And, as the gas cushion is slowly stolen away by the liquid it is normal to then oversize them by a factor of three. Concequently, they tend to be 6 times larger than you would think; so, "small" sizes are irrelevant.
