Performance characteristics

By combining M-BUS electronic remote transmission technology with RF card prepaid technology, users can conveniently purchase water while the management department can achieve remote reading management;

It has a complete tiered billing function, with a maximum of 4 tiers in the table, corresponding to 4 tiered water prices. Monthly billing is based on the tiered water prices corresponding to the tiered usage;

The entire meter adopts a fully sealed design with no exposed interfaces. The unique fully waterproof compartment design can effectively prevent external factors such as moisture, dust, oil fume, and human attacks from affecting electronic circuits. The waterproof level reaches IP67;

The meter supports two modes of billing: tiered billing and water volume billing. Tiered billing is calculated by deducting the amount, and can implement two sets of billing schemes: annual tiered billing and monthly tiered billing. Water volume billing can be calculated by deducting the amount of water;

Unique infrared identification radio frequency card detection technology, with a detection range of 0-15mm, easy to operate, and high reliability; Can be integrated with RF card tiered billing meters to achieve one card, up to one card carrying one meter and three meters;

Split type battery compartment design, using plug-in high-energy lithium batteries for more convenient replacement, and with power-off valve closing function;
