ID-227 Oil sheen sensor

wave rider float maintains position
minimal maintenance
early detection

The LEAKWISE ID-227 Oil Sheen Sensor for marine applications is used for the early detection, warning and control of oil leaks and spills in off-shore applications including intake towers of desalination plants, oil tanker loading bouoys and piers, oil rigs and lagoons.

The ID-227 is also deployed in lakes and rivers, open channels and retention ponds.

The ID-227 system consists of a:

Sensor with a high frequency transmitter mounted on a wave rider float
Separate controller
Cable connecting the sensor and controller (wired model only)

The wave rider float is designed to maintain the position of the detecting antenna at the liquid/air interface, despite fluctuations in the water level due to waves and tide. 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

The ID-227 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.
