The MEI Datalogger device monitors the wastewater treatment system, collecting data from sensors via RS485 (Modbus RTU), pulse input and 4–20mA analog signals such as pH, COD, TSS, DO, flow, water level. The device is capable of controlling the sampler automatically by time or flow, and recording full event logs.
Data is stored in parallel online and offline, automatically sent compensation when there is a network outage and safely backed up when there is a power outage. The system connects to the platform MEI Eco Web App for real-time monitoring, exporting reports and transmitting data to management agencies according to regulations.
Equipment Datalogger MEI is a specialized data collection and monitoring solution for industrial and urban wastewater treatment systems. The device integrates multiple signal standards, ensuring full collection of environmental parameters according to management requirements.
