NB IoT IoT water meter (non-magnetic+direct reading) is a remote water meter developed for the practical needs of intelligent management of water supply companies, which is convenient for remote meter reading and control. It adopts non-magnetic technology to achieve high-precision measurement with three decimal places, combined with our company's patented direct reading technology to regularly correct the readings on the meter end, to ensure that the mechanical and electronic readings are consistent, and to solve the problem of cumulative errors in traditional non-magnetic meters. The upstream adopts NB IoT narrowband cellular IoT technology to upload data to the background, integrate electromechanical conversion, and data transmission into a remote water meter without any intermediate collection devices. Making remote meter reading and control more convenient and reliable, while saving manpower, material resources, and financial resources, effectively improving production efficiency, especially suitable for installation in sparsely populated environments where wiring is difficult.
