2 Description
The Bonderite ® E-CO Level Controls are used to maintain liquid levels in operating chemical
tanks. Working on factory air supply, these controls offer a fail-save technique of solution
level control accurate /- ¼ inch.

Each level control can be supplied in multi-point configurations for customized
applications.

The system is not affected by agitation in the tanks or by corrosive action of the
contents. No ball floats, needle valves or hazardous electrodes are utilized. Only
the chemically resistant air probe is in direct contact with the process solution.

Batch operation may be accomplished by utilizing the “High-Low” option. A
measured amount of liquid may be added, and chemical additions and/or agitation
then provided. After chemical reaction, the vessel may then be emptied and the
process repeated.

Automatic tank heater and pump protection may also be controlled by the “High-
Low” option.

o
Saves in unnecessary use of water and excess manpower usage to perform
the consistent checking and adjusting of solution levels.
The level is maintained by detecting slight variations in air pressure due to changes in the
liquid level surrounding an immersed air probe. Immersion depth is typically a minimum
