The AQUAS HMI Multiparameter Water Quality Controller is an advanced instrument designed for real-time monitoring and control of critical water quality parameters in water treatment, wastewater treatment, and environmental monitoring systems. Built to integrate seamlessly with SCADA automation platforms, this controller functions both as a local interface and a networked data hub. Its robust hardware supports a wide range of communication methods, including cellular, Ethernet, RS-485 Modbus, Bluetooth, and GPS connectivity, allowing remote access, data upload, and real-time supervision of treatment processes.
This controller excels in versatility: it can connect up to eight smart digital sensors simultaneously, each capable of measuring vital process variables such as free chlorine, pH, oxidation-reduction potential (ORP), temperature, conductivity, dissolved oxygen, turbidity, salinity, flow, velocity, level, and pressure. With such broad direct sensor connectivity, the controller minimizes the need for intermediary signal converters or additional modules, leading to a cleaner installation and reduced field wiring complexity — a significant advantage in large-scale municipal or industrial water treatment plants
Built for demanding environments, the unit is housed in a rugged enclosure (typically IP66/NEMA4X rated) that protects internal electronics from dust, moisture, and harsh outdoor conditions. This durability ensures continuous operation even in locations such as reservoirs, pumping stations, and remote wastewater facilities. The internal data logger can store millions of readings, supporting historical trending and post-event analysis without needing an always-on network connection. For automation engineers and operators, this controller integrates smoothly with SCADA systems using standard protocols like Modbus TCP/IP, HART, and OPC, enabling it to act as a data source for real-time dashboards, alarm notifications, and centralized control systems. Alarm outputs, threshold conditions, and event logging are all configurable via the onboard HMI (Human-Machine Interface), which displays real-time process information, sensor status, and communication health.
Practical applications include municipal drinking water plants where regulatory compliance and water safety are critical, wastewater treatment facilities requiring efficient pollutant monitoring and control, and industrial settings where water process stability affects product quality. The controller’s versatility and utility make it a cornerstone component of any comprehensive SCADA-based water treatment automation system.
