If the measuring medium is a special gas, it can also display instantaneous standard condition flow rate and standard condition cumulative flow rate.
10. Query function:
It can query the daily, monthly (including the current month), and annual cumulative quantity reports of the past year, and can also query the total number of power outages and cumulative time of the last 20 power outages.
11. Real time curve and historical memory function:
Using high-capacity FLASH flash memory chips to store historical data: Depending on the recording interval, data from 7 days to 365 days can be stored and recalled.
12. Automatic repair function:
In addition to the software watchdog, the hardware system is equipped with a watchdog and a power on/off reset system. In case of program errors or unexpected crashes, the instrument can be forcibly restored to operation.

13. Power off protection function:
The calculation results inside the machine and the data set by the user will not be lost during power outage and will be saved for more than ten years.
14. Automatic judgment function for superheated steam to saturated steam:
When the selected superheated steam is converted to saturated steam during operation, this table will automatically judge and compensate according to the density of saturated steam. If it is converted to superheated steam again, it will also be automatically judged.
15. Working power supply:
AC:220V±15%； Power consumption: less than 5W
