PD-LFC (NB-IoT version) based on the volumetric liquid filled type mechnical water meter with pulse output and transfer the data via NB-IoT network to the smart metering management system (Platform).

● The transmission module and base meter of the water volume meter is separately installed, easily exchanged. The power supply battery is independently packaged and is convenient to replace.

● Use the latest NB-IoT data transmission technology, network cover wide, signal is stable and reliable.

● The transmission position is 1L.

● Based on the original base meter, the water volume meter can directly install transmission module, only increase 28CM, the module can rotate, it's very easy and convenient to install.

● The base meter adopt the independent function pointer, after installing the electronic module, it doesn't affect any reading.

● During the process of water meter with transmission module, it often happen the problem of repeated counting because the water ow reverse and shake. Using two sensors and a special algorithm can ensure the accuracy of the count.

● 26500+SPC1520 power combination technology.
