Introduction:

The non-magnetic NB water meter developed, manufactured, and sold by Shenzhen Yima Xinnuo is based on non-magnetic sensor technology, which collects phase information and calculates the direction and number of rotations of the rotating axis. Equipped with a high-sensitivity wet water meter and NB IoT IoT transmission module, it ultimately achieves high-precision measurement, anti magnetic interference, and remote IoT transmission functions.

Due to its wide coverage area, ultra-high safety and reliability, low cost, and low functional consumption rate, it is favored by many management departments because it can effectively solve problems such as magnetic interference, old meter renovation, or wiring difficulties in new community construction; And even the meter reading problem has been solved. Effectively avoiding the inconvenience caused to both parties when staff come to check the water meter.

Introduction to the functional advantages of non-magnetic NB water meter:

(1) Adopting advanced low-power wireless technology to solve the problem of difficult construction wiring;

(2) The effective meter reading distance is large, with end amplification and automatic frequency calibration functions, effectively improving wireless communication effectiveness;

(3) Adopt a center frequency of 495MHz, reasonably avoid the 471-486MHz frequency band of the power system, and avoid mutual interference. On September 9, 2013, State Grid Corporation of China issued the enterprise standard "Based on Micro Power Wireless Communication Data Transmission Protocol";

(4) Adopting ultra-low power consumption design, equipped with large capacity and long-life SAFT batteries, with a service life of over 6 years;

(5) Private network, dedicated account, stable and reliable communication;

(6) Pre deposit 10 years of communication fees, no need to consider recharge issues;

(7) Support prepaid function, no checkpoint, no carrier, more reliable;

(8) Support tiered water pricing, which can be set to 5 tiers;

(9) Support remote price adjustment, automatic switching of daily unit price during price adjustment;

(10) Support remote meter reading, remote valve control, remote parameter setting, remote recharge and payment, etc;

(11) Record historical data for the past 60 days, facilitating the drawing of historical curves and querying of historical data;

(12) Regularly sending/receiving data, with flexible setting of sending/receiving cycles (daily mode, weekly mode, monthly mode);

(13) It has multiple protection functions such as power failure protection, anti strong magnetic protection, and alarm function;

(14) Support remote hardware program updates and on-site battery replacement without dismantling the meter.
