Ultrasonic Residential Smart Gas Meter NB-IoT
Residential gas meters “Smartico” are produced by the size range G-1.6, G-2.5, G-4, G-6. They are used to measure the volume of used natural and liquefied gas, with conversion to standard reference conditions at a temperature of 20 °C. The meter is made in a compact design, which has no moving mechanical parts and allows mounting in a confined space. The meter measurement system provides high-precision metrological characteristics.
The meter provides the possibility visual control and wireless data transmission by Narrow Band (NB-IoT) technology which is focused specifically on indoor coverage, low cost, long battery life, and high connection density.
