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

2. Good repeatability, short-term repeatability can reach 0.05% to 0.2%, precisely because of its good repeatability, such as frequent calibration or online calibration can obtain * * degrees, it is the preferred flowmeter in trade settlement;

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

4. High frequency signals (3-4 kHz) can be obtained, with strong signal resolution;

5. Range measurement, with a medium to large caliber of up to 1:20 and a small caliber of 1:10;

6. Compact and lightweight structure, easy installation and maintenance, and high circulation capacity;

7. Suitable for high voltage measurement, there is no need to open holes on the instrument body, making it easy to make high voltage instruments;

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

9. Can be made into an insertion type, suitable for measuring large diameters, with low pressure loss, low price, can be removed without interruption, and easy installation and maintenance.
