Yamada offers a series of easy to install Liquid Level Controllers, each designed to sense and control the level of fluid at fixed and adjustable set-points. Once the controller maintains the predetermined level, a signal automatically switches the pump on or off based on the value around the set-points.
LLC-2Y Liquid Level Controller is a totally pneumatic system designed to automatically start and stop Yamada Air-Operated Double Diaphragm Pumps when the liquid level within a tank, sump, etc. reaches predetermined levels.
LLC-3 Sump Pump is a traditional “float type” system designed for a 5 gallon pail or sump of equal depth. The pump is controlled by an internal float which actuates an air valve. As the liquid level in the sump rises, the pump automatically starts and operates until the liquid level drops below a predetermined level.
