Wireless Internet of things water meter
Photoelectric direct reading Internet of things remote water meter
The remote transmission adopts photoelectric direct reading, which makes the data more accurate and reliable. The battery does not need real-time power supply, and only supplies power at the moment of meter reading, so the battery life is longer.
Detailed Introduction
Product principle
The photoelectric direct reading remote water meter is a kind of electronic remote water meter, which takes the mechanical water meter as the measurement base meter and uses the photoelectric signal to identify, convert and output the electronic reading.
Product Features
·Only working at the moment of meter reading, there will be no measurement disputes caused by asynchronous primary and secondary instruments due to pulse accumulation errors.
·Electromechanical conversion does not require real-time power supply, avoiding management risks caused by battery factors.
