MEI Group's 4G connected adverse pressure point monitor is a specialized monitoring device for water supply systems, designed to measure pressure at locations far from pumping stations or at points at risk of low or high pressure. The device uses a 4–20mA or 0–10V pressure sensor, high resolution, to help continuously monitor pressure and send instant warnings when detecting pressure drops, pressure shocks or abnormal fluctuations on the pipeline. In addition to pressure, the device also measures

System Data Logger monitors MEI Use microcontroller STM32F4, integrated 08 Analog Input channels 4–20 mA, 04 Pulse Counter channels and extended support LoRa to collect data from multiple measurement points. Connected devices 4G LTE, transmit data to the platform MEI ECO via protocol MQTT, support Continuous Mode and Low Power Mode. Built-in memory enabled save data offline for up to 120 days with cycle 15 minutes/time, automatically syncs when the connection is restored. Users can remotely conf

MEI pressure monitoring system is the kit Data Logger IoT Use microcontroller STM32, power supply 9–12VDC, supports pressure sensor connection 4–20 mA for continuous monitoring of water supply systems, pumping stations and industrial pipelines. Data is displayed on the screen, transmitted to the platform MEI ECO through protocol MQTT and supports two operating modes: Continuous Mode and Low Power Mode. Integrated equipment Offline Data Logging, automatically synchronizes data when the connection

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 th
