The floatmechanism mounted within the vesseloperates a ceramic coated magnet. As thefloat moves it pivots the magnet. A magneti-cally actuated sensor on the outside of thesolid metal housing reacts to the innermagnet movement.

After the low level sensor isdeactuated the indicator shows "red" until the high levelsensor is actuated. (OKC-3171F shows "red" during pumpdown.) NARROWBAND LEVEL CONTROLThis panel is used for control of liquid level over thedeadband of the PNEUMATIC FLOAT VALVE (approximately1/4" to 1/2"). The control panel pilots a fill or drain valvethat operates a pump. A normally open FLOAT VALVE is output control is "on" (indicator red) when the level islow and is "off" when the level is high (indicator green).
