Rotor wet multi-flow non-magnetic signal NB-IOT smart water meter based on the wet multi-flow meter, through the electromechanical conversion mode of non-magnetic counting function, NB-IOT network form of data remote transmission, a water meter for centralized management.
The non-magnetic signaling water meter uses the eddy current effect. According to the Faraday electromagnetic induction principle, when the massive metal conductor is placed in the changing magnetic field or the magnetic field line is cut in the magnetic field, the induced current in the conductor will be vortex-like.
peculiarity
1, the signaling module and the base table adopt split installation, good interchangeability; Power supply battery independent package, easy to replace the battery;
2, the use of the latest NB-IOT data transmission technology, wide network coverage, stable and reliable signal;
3, the sending bit can be measured by 1L bit or 10L bit according to the demand, which can meet different needs and high measurement accuracy;
4. On the basis of the original base table, the signaling module can be directly installed, and the installation bit boarding requirement is low and convenient;
5, the base table uses an independent function pointer, after installing the electronic module, does not affect any reading;
6. For the repeated counting caused by the backflow and jitter of the water flow in the process of using the signal water meter, the accuracy of the counting is guaranteed by using two sensors and special algorithms;
