Task
To develop a superaccurate metering instrument to measure gas consumption using up-to-date ultrasonic technology and to transmit data by a wireless link.
Solution
- No moving parts, which means no mechanical wear and more accurate and reliable measurements
- Capability of daily data transmission to a base station and/or router and, further, the end user’s account for gas consumption monitoring purposes
- Gas backflow monitoring and indication at the meter display; backflow measurement independently of the direct flow
- Low susceptibility to magnetic fields
- Low susceptibility to deposition in the flow section due to the ultrasonic measurement method
- Ultrasonic sensor and temperature sensor failure monitoring, gas overflow monitoring, low battery indication, prompt user notification of a failure or emergency (in the user’s account)
- Data transmission by NB-Fi protocol
- Integrated battery for 6 years of continuous work
- Aggregate gas consumption storing in the meter memory for at least 20 years
- Ambient temperature for indoor meters: -10 to +55 ° Ambient temperature for outdoor meters: -40 to +55 °C
