WP-SDC / WPI-SDC (NB-IoT application) is the smart water meter based on woltman /tangencial dry type water meter, the meter reading is transferred via pulse output cable and connect with NB-IoT module for wireless remote reading and realize multiply functionalities include real time flow status monitoring and consumption behavior analysis.

● The transmission module and base meter is separately installed, easily exchanged. The power supply battery of the woltman bulk water meter 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, it 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 in the woltman bulk water meter.

Main Technical Data

The battery inside the NB-IoT module is replaceable. If the meter has already been installed, it no need to remove the module, just directly replace the battery.
