Radio Telemetry System for Large Dairy to stop contaminated water entering watercourses
Oriel SystemsMay 03, 2012 16:05 BST
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.
- Radio Link provides cost savings over cabling
- Remote interrogation of on-site conditions
- Automation of Gates saves staffing costs
- Cost-effective solution
