1.  Features no mechanical moving parts, corrosion resistance, stability, reliability, and a long service life, with no special maintenance required over extended operation periods.

2.  Employs a 16-bit microprocessor chip, boasting high integration, compact size, excellent performance, and robust overall functionality.

3. It integrates the flow probe, microprocessor, pressure and temperature sensors into a compact structure, and automatically tracks and compensates in real time and corrects the compression factor

4.  Utilizes dual detection technology to enhance detection signal strength and suppress interference caused by pipeline vibrations.

5.  Equipped with a dot matrix LCD display in Chinese, it directly shows instantaneous volume flow rate under working conditions, standard volume flow rate, total volume, as well as medium pressure and temperature parameters. 

6.  Adopting EEPROM technology, parameter setting is facilitated and can be permanently saved, with the capacity to store historical data for up to one year.

7.  The converter outputs frequency pulse, 4-20mA analog signals, and is equipped with an RS485 interface, allowing direct networking with a computer.

8.  Offers multiple physical parameter alarm outputs, with users having the flexibility to select any one as per their requirements.
