Control Air L100 Bubble Tube Liquid Level System
The L100 Bubble-Tube Level System is a fully self contained instrument (liquid level system), requiring only connections to air or gas supply, dip tube and electrical power source to provide precise level measurement. Because only the stationary dip tube and the purge gas come in contact with the liquid, this system is ideal for applications involving hazardous locations or liquids which are highly corrosive, viscous, hot, (molten metal), explosive, slurry type or foodstuff. Some of the specific applications include waste and water treatment plants for municipalities and trash to energy plants. In addition, the electronic output from the L100 is compatible with almost all analog instrumentation, including local and remotely-located indicators, computers, data loggers, recorders and controllers.
