The INVALCO Model CMAS-203 is a snap-action, float-operated pneumatic liquid level control. A stainless steel float drives a three-way Micro Valve to signal a diaphragm valve, and an operation override (check knob) lets you adjust set points without disturbing the process level.

Note: the bulletin dimension drawing gives some metric conversions that do not match the inch values (e.g. 1.5" shown as 100 mm and 3.6" as 240 mm in one callout; the adjacent callout correctly shows 38 mm and 91 mm).
