Radio telemetry for large dairy to stop contaminated water entering watercourse

Oriel Systems have just completed a project for a large dairy in Wiltshire providing Automation and Control of a pair of Rotork Actuators and Penstocks

Automation was required to prevent run-off water contaminated with milk powder from the manufacturing process entering the local watercourses until it had been tested for water quality purposes.

In normal operation the run-off water is stored in a large holding pond some distance away on site which is subject to evaporation and refilling through normal precipitation.  The distance and the terrain proved unsuitable and too costly to run cables between the penstocks and the sensor so Oriel reccomended the use of a low power radio link between the two locations.  Oriel engineers installed an Ultrasonic Level sensor at the holding pond along with an Oriel Intelligent Telemetry Outstation or ITO that would accept the water level signals.   In cases of extreme precipitation and when the holding pond reaches it’s upper level and only once waterquality testing has been performed and found to be of acceptable quality can the signal be sent over the radio link to the Actuators and allow operation of the Penstocks to release water to a safe level into the local watercourse.

The radio link provides cost savings for installation over traditional cabling and allows remote interrogation and control of on-site conditions and has proved to be a cost effective and reliable solution for automating the penstocks along with providing a reduction in staffing costs
