ID-223 Oil Sheen Sensor for wet / dry sumps
The Leakwise ID-223 sensor detects the presence of and monitors the buildup of thin layers of hydrocarbons in wet and dry environments. Many petroleum and power companies have installed the ID-223 in wet or dry sumps for early detection, warning, and control of oil leaks and spills
A Leakwise system consists of a controller and one or more
sensors (also called detectors). The ID-223 sensor has a
high frequency transmitter mounted on a float built in a
guiding cage. The floating sensor maintains its position
precisely at the liquid/air interface, despite fluctuations in the
liquid level. The ID-223 is controlled by the analog PS-220
Controller, which has two field-adjustable alarm points:
- Low oil alarm – Detection of a first predefined layer
thickness of hydrocarbons - High oil alarm – Detection of a hydrocarbon layer at a
second predefined thickness, or detecting a dry sump
situation in certain applications
The ID-223 can detect as little as 0.3 mm (0.01 in) oil on
water reliably, repeatedly, and without false alarms. It can
also monitor on-line changes in oil layer thickness up to 20
mm (0.8 in). The Controller relays are used for local and
remote alarms and control. Continuous built-in diagnostics
monitor sensor operation. A stilling well (available as an
optional accessory) is recommended for ID-223 installations
where lateral water velocity exceeds 30 cm/sec (11.8
in/sec).
