1. No removable parts, corrosion proof, stable and reliable, long service life, long-term operation without special maintenance.
2. Use 16-bit computer chip, high integration, small size, good performance, powerful overall instrument function.
3. According to requirements of different users, there are various high, medium and low converter (electronic meter) configurations.
4. Various structures, split, integrated flange, clamp and so on, integrated flange can integrate flow probe, microprocessor, pressure and temperature sensor. With built-in combination, make the structure more compact, can directly measure fluid flow, pressure and temperature. For gas measurement, can realize automatic real-time tracking compensation and compression factor correction.
5. According to user requirements, can use dual detection technique which can effectively improve the strength of the detection signal, and to suppress the interference caused by the vibration of the line.
6. Use convertor (electronic meter) with domestic leading intelligent vibration resistance technology which effectively suppresses interference signals caused by the vibration and pressure fluctuations.
7. Use Chinese characters, English dot matrix display with more display digits, easy and intuitive to read.
8. Converter (electronic meter) can output frequency, pulse, equivalent, four-wire 4-20mA, three-wire 4-20mA and two-wire 4-20mA, analog signals, RS485 interface, Hart protocol output.
9. Use EEPROM technology, convenient for parameter setting, can be saved permanently.
10. Historical data can be saved up to a year.
11. Overall unit is with low-power consumption, with lithium battery power supply, or external power supply of 12V, 24V.
