NB-IoT Wireless Remote Transmission Electronic Gas Meter with Steel Case WG2.5W～WG10W

NB-IoT wireless remote transmission electronic gas meter with steel case WG2.5W～WG10W

Product introduction

The wireless remote transmission electronic gas meter is based on a diaphragm gas meter with a transmitting device, and is equipped with an electronic control module with a special security chip, and adopts non-magnetic sampling technology, thus improving the metering accuracy and sensitivity of the diaphragm meter and achieving cost-effective high-precision metering. At the same time, the meter adopts NB-IOT connection network, which can monitor the operation status of the gas meter, the accumulated gas consumption, the current remaining quantity and other data in real time. This meter is the latest high-tech product of our company, and is the best choice for city gas companies to realize gas supply automation and scientific management.

Main functions

1. Power-off valve function: After the battery is disconnected, meter will close the valve and save the data, and after the power is reapplied, the data will be the same as before the power failure.

2. Voltage detection function: The regular detection of battery voltage, when low battery power, the valve closes the valve. Replace the battery, the voltage returns to normal, the valve automatically open the valve.

3. High-resolution metering function: The module adopts the latest non-magnetic sampling technology, measuring every 0.0001M3, can accurately monitor the tiny flow leakage, when a small flow leakage and oversized flow leakage is found, take the initiative to close the valve and upload fault information to fully protect the safety of gas.

4. Anti-magnetic function: The latest non-magnetic sampling technology, the external magnetic field does not interfere with the sampling, does not affect the normal use of gas and measurement of users, improve the user experience at the same time, to ensure accurate measurement.

5. Remote meter reading function: The real-time gas consumption, meter status, time, battery voltage signal strength and other parameters of the meter can be read remotely.

6. Remote valve control function: the valve can be remotely switched on and off remotely through the remote. The remote valve closing is divided into authorized valve opening and unauthorized valve opening. When the valve is authorized, the valve can be opened through the key after closing, otherwise the valve must be opened through wireless.

7. Timing upload function: Timing upload data function can be set. (Default is one upload a day).

8. Remote upgrade: the equipment can be upgraded by remote means.

9. Data confidentiality: ESAM chip is used for data confidentiality to avoid data loss
