ID-223 Oil Sheen Sensor
Documentation
Specifications
Overview
Leakwise system consists of a controller and one or more sensors.
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 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 also monitors online changes in oil layer thickness up to 20 mm (0.8 in) and report it through a 4-20 mA output signal from the controller. Controller relays are used for local and remote alarms and control. Continuous built-in diagnostics monitor sensor operation. The SLC-220 digital controller handles up to four sensors. A stilling tube (available as an optional accessory) is recommended for ID-223 installations where lateral water velocity exceeds 30 cm/sec (11.8 in/sec).
Leakwise ID-223 has three sub-models for different maximum water fluctuation capabilities:
ID-223/500 – up to 500 mm (19.7 in)
ID-223/2000 – up to 2,000 mm (6.6 ft.) as standard, or up to newline
5,000 mm (16.4 ft.) on request
ID-223/2500 – up to 2,500 mm (8.2 ft.) as standard, or up to newline
5,500 mm (18 ft.) on request
