1. High accuracy, generally up to ±1%R, ±0.5%R, high-precision type up to ±0.2%R;

2. Good repeatability, short-term repeatability up to 0.05%~0.2%. It is precisely because of its good repeatability that frequent calibration or online calibration can obtain extremely high accuracy, and it is the preferred flow meter in trade settlement;

3. Output pulse frequency signal, suitable for total volume measurement and connection with computer, no zero drift, strong anti-interference ability;

4. High frequency signal (3~4kHz) can be obtained, and signal resolution is strong;

5. Wide range, medium and large diameter can reach 1:20, small diameter is 1:10;

6. Compact and light structure, easy installation and maintenance, large flow capacity;

7. Suitable for high-pressure measurement, no holes are required on the meter body, Easy to make high-pressure instruments;

8. There are many types of special sensors, which can be designed into various special sensors according to the special needs of users, such as low-temperature type, bidirectional type, downhole type, sand mixing type, etc.;

9. It can be made into an insertion type, suitable for large-caliber measurement, with small pressure loss, low price, can be taken out without interruption, and is easy to install and maintain.
