Product Description
NWM MJ-VC Wireless Valve Control Water Meter
is the water meter combined with integrated chip technology with optical sensors as well as communication module, realizing function of wireless remote data reading and remote valve control; It is a terminal by itself which does not need the help of intermediary transmission instruments such as concentrator,data collector. It communicates with the network directly, it complies with ISO 4064:2014 standard, approved with BA Z-14-1131 ,it is used to measure the total amount of portable water passing through the pipeline and is a perfect choice for industrial or domestic water meter application in modern smart water management.- Technical Data
