The ID-223 Oil Sheen Detector from Leakwise can be installed in dry or wet sumps to detect oil leaks from above ground oil storage, and a range of other applications.

The ID-223 has three different models (ID-223/500, ID-223/2000, ID-223/2500) with range of detection from 40 to 2500 mm.

The ID-223 can detect as little as 0.3 mm layer of oil on water reliably, repeatedly, and without false alarms. It can also monitor on-line changes in oil layer thickness. The signal processor relays can initiate both local and remote alarms, as well as control. Continuous built-in diagnostics monitor sensor operations.

The ID-223's high frequency transmitter is mounted on a patented float built in a guiding cage, which maintains its position precisely at the liquid/air interface, despite fluctuations in the liquid level.

The ID-223 Oil Sheen Detector is used in conjunction with one of three controllers, depending on the application.

  • The PS-220 Controller is an analog signal processor and power supply in a NEMA 4 enclosure, and supports a single ID-220 Leakwise sensor.
  • The SLC-220 Digital Signal Processor for Multiple (2 / 4 standard, more in a network) ID-220 Series sensor support, with various output options, including relay, lights, 4-20 mA, LCD, Modbus in RS-232 and RS-485 communication, and cellular remote connectivity.
  • The WSP-220 Wireless communication – Point-to-Point data radio.
