Permanent PLC-based Solutions

Product Options


The BD3 and BD4 solutions incorporate a PLC at the heart of the design for real-time SCADA process control applications. A weatherproof enclosure contains all components and can either be integrated into existing systems or can be wall mounted adjacent to the sensors. The BD3 enclosure measures 747h x 536w x 300d and for the BD4 design an additional identical enclosure is used to house the flow cell, sonde and pump.

The BD3/BD4 solutions are ideal for measuring a range of water quality, flow, level and meteorological applications and has options for RS232/RS485, modbus, analogue and pulse inputs. These solutions are ideally for process control applications where continuous real-time data is required; applications such as aeration control, Full Flow to Treatment and Final Effluent Monitoring. With real-time control at your finger tips using parameters such as BOD, COD or TOC, it is possible to have greater control of WWTW processes and indeed react quicker to water quality imbalances that could be caused by trade effluent spikes or storms.
