ELMAG 400-Integrated Multivariable Flow and Water Quality Monitor
INTEGRATED MULTIVARIABLE FLOW AND WATER QUALITY MONITOR
ELMAG 400
The ELMAG 400 is an advanced Integrated Multivariable Flow and Water Quality Monitor designed to provide comprehensive monitoring of both flow and water quality through a single intelligent instrument. By combining electromagnetic flow measurement with multiple analytical sensors, it eliminates the need for several individual instruments, reducing installation costs, maintenance, and system complexity.
The ELMAG 400 simultaneously measures Flow, Velocity, Pressure, Temperature, Conductivity, TDS, pH, Dissolved Oxygen (DO), Chlorine, and Turbidity, delivering accurate, real-time process data for effective monitoring and control. Built on the proven electromagnetic flow measurement principle, the full-bore design ensures zero pressure loss, high measurement stability, and reliable performance in conductive liquids.
Designed for demanding industrial and municipal applications, the instrument features a touchscreen display, integrated data logger, and support for SCADA, GSM, GPS, and Modbus RTU communication, making it ideal for modern automation and remote monitoring systems. The replaceable analytical sensor design minimizes maintenance while maximizing service life.
Manufactured and calibrated in an ISO/IEC 17025 NABL-accredited calibration laboratory, the ELMAG 400 delivers dependable accuracy and repeatability for continuous process monitoring. It is suitable for water treatment plants, sewage treatment plants, drinking water systems, industrial water monitoring, smart city projects, process industries, power plants, pulp & paper, chemical, and pharmaceutical industries.
The ELMAG 400 is the ideal solution for organizations seeking a reliable, intelligent, and cost-effective instrument for integrated flow and water quality monitoring.
