Tuffy® pneumatic side-mounted float switch
The Pneumatic Tuffy® liquid level switch is a compact pneumatic level switch designed for horizontal mounting in a tank or vessel through threaded or flanged pipe connections.
Technology
Float level switches - Buoyancy
All float operated liquid level controls operate on the basic buoyancy principle which states "the buoyancy force action on an object is equal to the mass of liquid displaced by the object." As a result, floats ride on the liquid surface partially submerged and move the same distance the liquid level moves. Because of this, they are normally used for narrow level differential applications such as high level alarm or low level alarm.
