PLC/SCADA Systems

Severn Controls has built its reputation on the design and installation of systems for the control of industrial processes of all kinds.

The company has developed advanced control technology which can be adapted to a very wide range of applications, from manufacturing processes to flow control.

Recent projects include:

• A chemical dosing system for industrial barrel washers supplied by Henkel Ecolab to a major industrial laundry chain. The system controls the precise metering of small quantities of up to 10 cleansing chemicals and calibrates dosing pumps. A SCADA (computer-aided) package monitors all functions and costs the chemicals used per wash, as well as providing valuable maintenance information.
• Flooding used to severely affect a part of the Severn Vale every spring tide when the flow from a small river was pushed back upstream by the tidal River Severn. Severn Controls were therefore asked to design, install and commission a land drainage system for the Lower Severn Drainage Board.
• A 35 cubic metre tank houses a submersible pump with an output of up to 180 litres per second. A variable speed drive allows precise control of pump speed depending on water level. An ultrasonic control unit monitors the water level in the tank and controls the pump as required, varying the drive speed to suit demand.
