Groundwater Remote Terminal Unit

Product introduction

MRTU8180 series RTU is powered by high-performance lithium batteries, and has multiple functions such as instrument data acquisition, equipment status monitoring, and 4G/3G/2G remote communication, especially suitable for monitoring without mains power supply and high waterproof/dustproof requirements. On site, it is widely used in the fields of water supply and drainage/oil/heat/gas pipeline network monitoring, groundwater monitoring, oilfield long shutdown monitoring, liquid level monitoring and other fields.

Product Features

Data acquisition: regularly collect the detection data of serial instrument, such as flow meter, collector, display instrument, etc. Remote communication: regular data communication with the monitoring center through GPRS/Short message.

Remote maintenance: support remote parameter setting and program upgrade.

Proximity maintenance: Support mobile phone APP to set parameters and program upgrades of the device through Bluetooth.


IP68 protection, waterproof, moisture-proof and dust-proof.

Compact structure, small size, easy installation.

Low-power design, with current as low as uA, extending battery life.

Compatible with common instruments, and drivers that are not compatible can be quickly developed.

Self-powered, comes with a large-capacity lithium battery pack. Powered by a high-energy lithium battery pack, providing sufficient energy.

It is suitable for all kinds of harsh environments, especially in manholes, semi-basements and so on.
