Equipment introduction

MBUS concentrator: It is a lightweight water meter concentrator that supports MBUS and 485 meter reading modes. It is powered by 3.6V lithium battery, operates with low power consumption, is easy to install, and has a service life of more than 6 years. The concentrator includes functions such as local command transparent transmission, collective reading upload, and overcurrent protection, which is very suitable for data collection of MBUS/485 water meters.

Equipment features

• Using NB-IoT communication technology, the signal strength is 100 times higher than the original 2G signal;
• MBUS/485 transparent transmission, MBUS/485 collective copy, MBUS/485 collective copy data storage;
• Voltage detection function;
• Concentrator mounting table address management, the concentrator can add up to 30 MBUS/485 water meter addresses;
• Overcurrent protection/remote upgrade/SIM card switching/Bluetooth communication, etc.;
