The STU mini device is designed for reading gas volume correctors, data collection, and data transmission, and can be easily connected to almost any SMART metering system.
The STU mini device connects to gas volume correctors via its built-in RS232 port. If necessary, the device can also supply power to the corrector’s serial port.
The device can also be connected to gas meters. By counting the consumption-proportional pulses emitted by the gas meters, it records hourly, daily, and monthly consumption data.
With its default hourly data collection mode, the device can store up to six months of data in its internal non-volatile memory.
The device transmits the collected data to the central server via mobile internet.
