Bubble Tube Liquid Level System

The L100 Bubble-Tube Level System is a fully self-contained instrument, that only requires connections to an air or gas supply, dip tube and electrical power source to provide you with a precise level indication.

As only the stationary dip tube and the purge gas come in contact with the liquid, this liquid level system is ideal for applications involving hazardous locations or liquids which are highly corrosive, viscous, hot, (molten metal), explosive, slurry type or foodstuff.

In addition, the electronic output from the L100 is compatible with almost all analogue instrumentation, including local and remotely-located indicators, computers, data loggers, recorders and controllers.
