Oil Water Separator Sensor | Veeder-Root

Oil Water Separator Sensor

Oil Water Separator Sensor

Key Features:

  • Activates visual and audible alarms on the TLS monitoring system when water or oil exceeds a predetermined threshold
  • Provides alarm conditions to control pump relays used to maintain proper oil and water levels
  • Alarm History retrieval via front panel/display, serial communications including Ethernet and printer
  • UL and cUL approved

The Oil Water Separator Sensor (OWSS) monitors product thresholds for proper operation of the oil water separator tank

OWSS Sensor Sizing

To determine the correct sensor length for the oil water separator tank application use the manufacturer's tank chart to determine height-to-volume thresholds for warning and alarm conditions and make three measurements, including verifying fluid depths on the manufacturer's tank chart which will determine the proper length of the sensor. See the Sensor Application Guide, Manual #577013-750, for specific sensor sizing and part numbers.
