Smart gas metering

LoRaWAN Smart Gas Meter:

A combination of base meter with built-in motor valve and smart controller with LoRaWAN communication module. It is the latest generation of LoRa wireless gas meter product that conforms to the LoRaWAN international standard. Based on high reliability network technology, prepaid module is strongly recommended for LoRaWAN gas meter which makes remote daily block pricing billing realizable, and to make sure the billing more reasonable and precise. The power consumption is lower based on the particular network communication, which makes the alkaline battery life time more than 1 year. . As the leading total solution provider in the gas industry, Goldcard provides the integrated solution for the utility. To satisfy varies requirement from different customers, Goldcard provides a solution from meter to system including LoRWAN gas meter, LoRWAN data concentrator, data collection system, data marketing system and data cloud platform.

HOW A LoRaWAN-BASED Water Meter SYSTEM WORKS

A water meter is a mechanical device with a series of internal gears. These gears move as water flows through the meter, recording your usage. This process is similar to how an automobile odometer records the miles as the tires rotate. All meters are factory calibrated to industry standards prior to being shipped, and last 10 to 15 years. After that time, they can begin to wear, allowing more water to flow through the meter than is actually recorded with the result being an underbilled customer. As SSTPL's installs new meters, we also upgrade the technology allowing us to electronically read meters. This is accomplished by sending a signal to a device attached to the meter that responds with the reading. This mobile computerized technology is more accurate and more efficient than manually reading meters.
