4100-OWS

4100-OWS Oil/Water Separator Level Monitor

Part Number Starting: 4100-OWS

Continuous interface monitoring of static level oil/water separators

This unique oil level system provides complete flexibility for monitoring oil water separators in one complete package.

The 4100-OWS sensing probe monitors the capacitance field between the probe and the concentric shield.

As the oil accumulates and displaces the water, the probe capacitance changes. This interface signal is used to provide outputs, displays and relay control.

Optional Interfaces

Analog Output 4-20 mA non-isolated

Communication RS-485 Modbus

  • No moving parts
  • Remote electronics via standard twisted pair
