A Large-caliber photoelectric direct reading remote water meter
A Large-caliber photoelectric direct reading remote water meter
1.Good flow performance
2.Photoelectric direct reading meter
3.Remote communication function
4.High degree of protection
5.Long lasting
6.Easy maintenance
The unique design guarantees low zone sensitivity and high zone flow performance of the water meter, and the anti-interference performance reaches the highest level UO, DO.
2.Photoelectric direct reading meter
Using infrared photoelectric projection sampling, the real-time reading value is exactly the same as the mechanical display value.
3.Remote communication function
Wired M-BUS or RS485 communication can be used, or Lora or NB-IOT can be used for wireless data transmission.
4.High degree of protection
With advanced copper sealing technology, the overall protection level reaches IP68, ensuring that it will not get wet and the surface will be covered by fog.
5.Long lasting
It adopts low-power design and is only powered by the acquisition device for a short time during reading. The electronic unit has short working time and long life.
6.Easy maintenance
The electromechanical conversion module adopts plug-in design, which can be installed separately from the water meter. The module is interchangeable and easy to maintain.
