Waste gets automatic treatment

A radio telemetry system will remotely monitor and automatically control scraper bridges at NorthWest Water’s Ellesmere Port Waste Treatment Works

Pantek Monitoring Solutions and SLS Engineering have jointly installed a radio telemetry system that will remotely monitor and automatically control scraper bridges at NorthWest Water’s Ellesmere Port Waste Treatment Works.

Part of a site wide optical fibre network project, the new system installed by Pantek and SLS is based around Pantek’s Maxiflex Radio Multiplexing technology. It will be used to provide remote monitoring and start/stop capability to scraper bridges at Ellesmere Port and to log all the data on the site’s Scada system thereby providing trends, alarms and historical data. Prior to this, the bridges were operated manually.

The design of the new system offers many benefits. By mounting a Maxiflex I/O system on the scraper bridges, Pantek and SLS have excluded the need for hard wire cabling and thus prevented North West Water incurring the cost of slip-ring technology, excavation and diamond drilling.

The Maxiflex I/O system can support all types of process signal and is flexible enough to allow cost-effective expansion in the future. It also provides a gateway for other remote data acquisition required by the site wide Scada system.
