Liquid Level Controllers

Diaphragm Pump Liquid Level Controller

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.

  • Pneumatic Operation – No electricity required
  • Energy Efficient – Pnuematic operation
  • On/Off Reliability – Automatically starts and stops at predetermined levels
  • Versatile – Single pump operation: controls fill or evacuation levels;
    Dual pump operation: controls both evacuation and fill levels simultaneously
  • Compact – space saving design controls pumps up to 20 ft. distance

LLC-2Y Level Controller 

LLC-3 Sump Pump Level Controller
This 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. The LLC-3 sump system cover comes complete with a diaphragm pump from the list below, float assembly (actuator and float ball with stem), filter-regulator gauge assembly, and suction pipe. All components are mounted on a 5 gallon lid and bucket.
