Technical content

T20 and T21 units are simple,reliable floatsw itches, designed for top mou nting intotanks or vessels.T20 units utilize a single switchmech anism and float.T21 tandem unitsutilize two switch mech anisms and two separate floats.T20 and T21 m odels are availablefor any type of open or closed vessel,with either threaded or flanged type mo unting,and actuatingdepthsofup to 48 inches (1219 mm).
