The ultimate in water treatment control flexibility
DULCOMETER diaLog X continuously monitors and controls a wide range of measured parameters and digital inputs to optimize the water treatment process. The DULCOMETER diaLog X can control and monitor metering pumps, valves, motors, and other output components to provide full automation of your system using the different parameters or measured variables The physical variables to be determined by measuring. more in the glossary through the various inputs. Control of these various devices is accomplished through flexible programing of the open platform controller via multiple standards, connectivity options and communications protocols.
Features and Benefits
- Excellent flexibility thanks to modular construction and easily extendible IO modules (input/output), allowing more sensors and pumps to be connected.
- Up to two satellite units can be added for additional inputs and outputs, allowing more sensors and pumps to be connected.
- Intuitive operation via the HMI (Human-Machine Interface) thanks to a clearly legible industrial display and robust keys for standard commands, such as calibration and monitoring.
- Simple configuration of process settings as well as monitoring and visualisation of process data via a web server with freely configurable and preconfigured software modules.
- Extensive overview and control of processes, e.g. cooling tower processes: All process data and alarms can be communicated to the process control system via fieldbuses such as Modbus RTU.
- Advanced communication options: Various network protocols such as FTP or MQTT enable remote access and data management via Wi-Fi and LAN (Ethernet).
