K512,Oil,Level,Controller,Kenco,EngineeringK512 Oil Level Controller


Operating Principle:
The KENCO Oil Level Controllers are designed to control a constant oil level in the crankcase of stationary engines, compressors, and mechanical lubricator boxes. The KENCO oil controller works in conjunction with an overhead oil supply system which feeds the oil level controller. As the oil is consumed, the oil controller supplies the required amount of oil to maintain a proper level in the crankcase. The oil controller maintains the proper amount of oil in the crankcase by using a float controlled valve. The valve opens and closes as oil is needed in the crankcase to provide a constant oil level.

The oil level switch in the K512 is a case to ground electric switch contact for non-hazardous locations. The level within the crankcase directly corresponds with the oil level in the oil level controller housing. If the oil level in the crankcase drops past the designated level, the switch will trip sending an alarm.


  • Locations where space is limited

  • Non-hazardous locations

  • Stationary engines and compressors

  • Mechanical lubricators

  • Pumps


  • Reduces maintenance by maintaining a constant lube level.

  • Protects against lubrication failure

  • Controller mechanism fully removable without draining oil

  • Adjustable mounting slots on back of casting eliminate need for mounting adapters

  • Easy view convex sight window

  • Switch test button available

  • Fire Safe Valves available

  • Oil outlets on either side of housing and in the bottom to allow for various piping configurations

  • Direct mount adapters eliminate equalizing problems and reduce installation costs
