1. Highlights
- Different from traditional gas meter (square-design), the straight-through design of U-GR3 gas meter greatly reduces gas loss and efficiently improves the accuracy of measurement.
- Its compact size makes it easier to install in various occasions, especially in small spaces such as kitchens and multiple pipe connections.
- With multipile communication, the U-GR3 supports GPRS, LoRaWAN.
