Intelligent discharge control system high precision — from 5–5000 l/s –modular extension.

The ElectroSlide Flow Regulator is a specially designed penstock enabling accurate flow calibration. The penstock is driven by an actuator, and can be installed in either upstream or downstream configurations. With high precision, the valve control – see illustration on the left – calculates from the impounded water level, the desired flow rate required (Q_ab); driving the slide position to provide the aperture area required. Dependent upon the type of control provided, it is possible that flow parameters can be adjusted remotely; however, in most cases the flow changes can be made directly into the plc unit on site. In most applications, a second sensor can be provided downstream of the ElectroSlide Flow Regulator which measures the water level in the discharge channel to ensure flow is being maintained. When the downstream flow is restricted the control recognises that a blockage has occurred and will pulse the ElectroSlide penstock unit open in steps until the blockage is cleared before returning to control. The ElectroSlide Flow Regulator opens the valve gradually to prevent excessive flow passing downstream. Obstructions larger than the valve opening can trigger alarm (optional as GSM signal). Sewer flushing can also be provided within the programme control if required. A specific impounding level can be input and when reached with pulse the ElectroSlide Flow Regulator will open fully for a set period before returning to flow control. 

A CP communications processor with ethernet interface is optional for connection to the control centre.
