Residential gas meters “Smartico” are produced by the size range G-1.6, G-2.5, G-4, G-6 and are used to measure the volume of used natural and liquefied gas, with conversion to standard reference 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 license-free frequency range using technology LoRaWAN.
Key features highlights :
Built-in temperature sensor and gas flow rate adjustment to standard conditions.
Absence of mobile mechanical parts, resistance to external magnetic field due to the use of an ultrasonic sensor.
Protection from external influences and transmission of an alarm message to the dispatcher's software when the case is opened.
Control and transmission to the dispatcher's software:
• presence of reverse flow;
• excess of the flow above the maximum allowable;
• the presence of an external magnetic field;
• battery discharge status;
• performance monitoring of internal sensors;
• gas flow below the nominal, which indicates a gas leak;
• determination of the gas/air;
• shock control and repositioning of meter.
Built-in non-volatile memory, archiving, built-in real-time clock.
Battery life 10 years.
Two systems of measurement: metric/imperial
Data transmission in the license-free frequency range using technology LoRaWAN EU868/US915.
Exclusion of the human factor when taking readings.
Reducing the cost of gas distribution by reducing the number of staff of the subscriber service.
Operative calculation of the balance of gas consumption in the house, district, city.
Timely invoicing of consumers for the actually consumed volume of gas.
Small size, aesthetic appearance, easy installation.
