▲Wet-type base meter, available in various materials such as copper shell, iron shell, plastic shell, and stainless steel shell.
▲The communication protocol of this series of water meters can be customized according to customer requirements.
▲ With an IP68 protection rating, it adapts to various harsh environments.

Details

Function Parameters Dimensions

This product is the SECK Non-Magnetic Smart Remote Wireless Water Meter. Based on NB-IoT narrowband cellular wireless communication technology, this low-power wireless remote water meter adopts a split-type design that preserves the structure of traditional water meters without compromising measurement accuracy or sensitivity. As an electromechanical integrated electronic remote water meter for automatic meter reading systems, it features ultra-low power consumption, high measurement accuracy, low minimum starting flow rate, convenient meter reading, aesthetically pleasing appearance, high sensitivity, strong anti-interference capability, and long transmission distance.

 

Working with intelligent meter reading system software, the non-magnetic smart remote wireless water meter performs intelligent meter reading for residential communities and enables networked data sharing with settlement centers.
