Process WorldWide, Intelligent Sensor Detects Petroleum Leaks to Prevent Water Contamination, Nov. 25

Electro-Chemical Devices (ECD) has introduced its new self-cleaning oil-in-water sensor – OIW80 which helps municipal water and wastewater facilities as well as industrial plants to quickly and accurately detect oil in water leak incidents. This technology helps one to take quick action in order to prevent contamination of drinking water, fouling of batch processes, damage to plant equipment or contamination of sensitive water ecosystems.

Engineers at municipal water or wastewater facilities and industrial plants will find that the new OIW80 Sensor from Electro-Chemical Devices (ECD) helps them to quickly, accurately and economically detect oil in water leak incidents requiring fast response actions to prevent further contamination of drinking water, fouling of batch processes, damage to plant equipment and/or contamination of sensitive water ecosystems.

The highly intelligent, precision sensor reliably measures oil in water over a range of 0 to 30 ppm (mg/L), and it can be factory preconfigured to measure oil in multiple ranges or easily set in the field, states the company. This rugged, high-performance responsive sensor operates over a temperature range from 41 to 113oF (5 to 45oC) to quickly detect leaks and alert plant technicians.

Designed for demanding and/or dirty plant environments, the highly dependable sensor features a built-in wiper cleaning system to remove bio solids and films that might cloud the sensor window’s visibility. The sensor features a built-in automatic screen window wiper that reduces technician manual checks and the frequency of scheduled maintenance cleanings.

The heavy-duty construction of the sensor’s rugged housing utilizes strong, corrosion resistant Stainless Steel (standard) or optional Titanium and meets the IP68 water ingress standard. Every aspect of the sensor’s design has been tailored for years of reliable operation and trouble-free service in the demanding wet environments typical of municipal and industrial water and wastewater treatment applications, adds the firm.

The versatile sensor features built-in RS485 serial communications and is Modbus/RTU compatible. Users can choose from ECD’s two-channel T80 Universal Transmitter or ECD’s eight-channel LQ800 controller, or a wide range of RS485/Modbus compatible third-party controllers. Up to eight LQ800 controllers can be networked to support large plant systems.

When the sensor is connected to the versatile ECD T80 transmitter or the ECD LQ800 controller, the sensor’s information is automatically uploaded to the analyzer. It then configures the displays and outputs of the transmitter to the values appropriate to the oil sensor’s measurement parameters. Its digital output communications are RS485/Modbus compatible.

The universal T80 Transmitters are available as either single channel or dual channel devices, allowing one analyzer to measure up to two parameters or two ranges. This transmitter is available in a 24 VDC or a 100/240 VAC power configuration. All versions are available with an optional HART output to support integration with larger control systems.

The highly scalable eight-channel LQ800 Multi-Channel Controller is designed to operate up to eight ECD digital analytical and process sensors. Its flexible design features Modbus communications, with optional HART, and is Cloud-ready allowing integration with larger systems. The LQ800 Controller is available as a 24 VDC or 100/240 VAC powered controller.
