Product Description

Product Overview

Type YW-TW intelligent gas meter based on the IoT adopts LoRaWAN/CAT.1/NB (optional) wireless transmission technology. Automatically upload gas consumption data to the application platform to realize remote monitoring of gas meter usage status. It solves the problems of the traditional gas meter, such as the difficulty of over-reading the meter at home, the difficulty of paying the fee, and the inaccuracy of the supply and marketing difference.Explosion-proof sign ExibIIBT3 Gb. It is applicable to Zone 1 and Zone 2, containing IIA-IIB and T1-T3 explosive gas mixture.

Our Advantages

1. Adopt LoRaWAN/CAT. 1/NB (optional) wireless technology. Effectively increase the anti-interference ability of the communication system and improve the accuracy of the received data; 

2. The gas meter adopts the form of system prepayment. The valve switch of the gas meter is realized by the command from the system platform; 

3. Timing (once a day) (settable) and key wake-up to transfer data to the platform. It improves the response speed of meter reading and reduces battery energy consumption; 

4. When the voltage is low or abnormal, the LCD screen will automatically display the fault information, beep the  alarm, and close the valve; 

5. It has a built-in antenna. The transmission signal is stable and reliable; 

6. The platform can remotely check the user's gas consumption, battery usage, and remotely control the valve switch of the gas meter; 

7. It has the function of pulse signal open circuit self-inspection, which can effectively ensure the accuracy of gas meter measurement;
