The Leakwise ID-221 detects floating oil sheens in wet sumps, tanks, ponds, and monitoring wells.

Leakwise ID-221 Overview

The Leakwise ID-221 Sensor, which is used with a Leakwise controller, is installed in sumps and groundwater monitoring wells to detect floating oil sheens resulting from oil leaks in underground storage tanks and pipelines. Additional applications include:

The ID-221 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 controller relays can initiate both local and remote alarms, as well as control. Continuous built-in diagnostics monitor sensor operations.

The ID-221's high frequency transmitter is mounted on a patented float, which maintains its position precisely at the liquid/air interface, despite fluctuations in the liquid level. It has two field adjustable alarm points:

A stilling well is recommended for all ID-221 installations.
