ID-221 Data-sheet

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:
  • Monitoring hydrocarbons and other organic solvents during site assessment and remediation
  • Detecting and monitoring floating hydrocarbons in sewer systems, waste water treatment systems, oil/water separators, cooling water trenches and canals, storm water run-offs, retention ponds and sumps, and boiler condensate tanks
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:
  • Low oil alarm — Detection of a predefined layer of hydrocarbons
  • High oil alarm — Detection of a hydrocarbon layer at a second predefined thickness
A stilling well is recommended for all ID-221 installations.
