Bubble-Tube Liquid Level System Provides Precision Transmission of Liquid Level in Open Tanks

Bubble-Tube Liquid Level System Provides Precision Transmission of Liquid Level in Open Tanks
ControlAir’s L100 Bubble-Tube Liquid Level System is a fully self-contained instrument, requiring only connections to air or gas supply, dip tube and electrical power source to provide precise level indication.

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 floodstuff.  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.

Features:

  • Totally Solid State
  • High Accuracy and Stability
  • Four Times Rated F.S. Overpressure Safety Factor
  • Visual Purge Rate Indication
  • Blow-Down Capability
  • Excellent for Hazardous, High-Temperature, Corrosive or Waste Water Level Measurement
  • NEMA 4X Enclosures Available

The L100 can be configured as a basic system which is standard, as a remote sensing unit, and as an automatic blow down unit.  The L100 Bubble-Tube Liquid System can also be custom-configured to specific application requirements.

Factory preset ranges are available from 0-50 inches water to 0-115 feet water or equivalent, full scale. Accuracy + 0.25% of span guaranteed; + 0.20% of span typical.  Includes combined effects of linearity, hysteresis and repeatability errors. Sensitivity is + 0.02% of span guaranteed. Repeatability + 0.10% of span guaranteed; + 0.05% of span typical. Operating temperature ranges from 300F to 1610F.
