One
of our most versatile level controls, the Model B-190
can be used on all types of tank or sump level control
applications. Three porcelain displacers provide deadband
adjustment. Unit can start a sump pump (for example)
when liquid reaches the high set point and turn the pump
of when the level drops to the low set point. Unit works
equally well in pressurized tanks.

SUGGESTED
SPECIFICATIONS
Liquid level control shall be top mounted displacer type with adjustable
deadband. Cable and spring shall be stainless steel. Motion of displacers
shall actuate switch by magnetic linkage. Electrical section of switch
shall be separated from process by solid metal. Switch shall be Mercoid
Model No. B-190WT-7810-1.0-4-125. |
|  Model
201 liquid level control is designed for long
life and reliable operation in chemical plants,
refineries and industrial facilities. Stainless
steel switching mechanism uses gravity return action
instead of springs to prolong life. Weatherproof
enclosure is standard. Heavy duty, welded steel
float chamber is suitable for 500 psi at 750°F.
