Photoelectric Water Meter

Photoelectric direct reading water meter

The photoelectric direct reading water meter adopts the principle of counterpoise photoelectric conversion, the mechanical reading and electronic reading are exactly the same, direct and reliable.

The photoelectric direct reading water meter adopts the principle of counterpoise photoelectric conversion, the mechanical reading and electronic reading are exactly the same, direct and reliable. It will not be affected by time and environment, which makes it difficult to read and false code, and can realize zero error real-time meter reading. With the remote transmission of data through the centralizer, this water meter can realize centralized meter reading management, which is ideal for use as a household water meter in multi-story and high-rise buildings. In addition, there is a wired communication between the meter and the concentrator, which is highly reliable. Users can remotely open and close valves or monitor and read water in real time.

  • Directly and reliably converted by photoelectricity, it is not subject to time and environment and has difficulty in reading and mis-coding. The mechanical readings and electronic readings are consistent, achieving zero error real-time meter reading.
  • The electronic part of the meter has no mechanical contact with the counter movement device, which does not affect the original measurement accuracy.
  • Directly read the word wheel window reading, no cumulative error, no need to set the bottom number of the meter, no need to store data.
  • No need for power supply in normal time, only need to be powered by bus at the moment of meter reading, no built-in power supply, long service life.
  • Not affected by external magnetic field and back current, the electronic module is normally in non-working state, not affected by whether the system is It is not affected by power failure, fault or interference or even lightning.
  • Each meter has a unique address code, which is convenient for management and maintenance.
  • Through the M-bus method, the word wheel reading of the water meter is read in real time.
  • Centralized reading through concentrator or collector, or single water meter reading, with real-time accurate data.
  • The electronic readings are identical to the mechanical readings of the water meter.

Wireless water meter

NB-IoT wireless remote non-magnetic water meter

By using non-magnetic sensors and special algorithms, NB-IoT wireless remote non-magnetic water meters are not only free from external magnetic interference, but also ensure the accuracy of counting.

By using non-magnetic sensors and special algorithms, NB-IoT wireless remote non-magnetic water meters are not only free from external magnetic interference, but also ensure the accuracy of counting. It is very suitable for the installation environment where the water flow is backflowing and jittering seriously. Moreover, the transmitter module can be installed directly on top of the original base meter, which makes the installation location less demanding and easy to operate. This water meter has the advantages of wide transmission range and low cost. In addition to the remote meter reading function, it can also realize the storage of user’s water consumption history and real-time water consumption monitoring, helping the water supply department to better improve their water management.

  • Non-magnetic on-board coil sensing and measurement, free from external magnetic field interference.
  • The transmission position can reach 1L measurement, with high measurement accuracy, which can realize forward and reverse measurement.
  • The electronic module and the base meter can be designed separately, and the interchangeability is good.
  • The power supply battery is individually packaged and can be replaced easily.
  • For the signal water meter in the process of use, it often appears due to the backflow and jitter of the water flow.
  • The repetitive counting, etc., are used to ensure the accuracy of counting through the use of non-magnetic sensors and special algorithms.
  • The signaling module can be directly installed on the basis of the original base meter, and the installation location is low and convenient.
