　　2、 Characteristics:

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

　　Good repeatability, short-term repeatability can reach 0.05% to 0.2%. It is precisely because of its good repeatability that frequent calibration or online calibration can achieve extremely high accuracy, making it a preferred flowmeter for trade settlement;

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

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

　　Wide range, with a medium to large caliber of up to 1:20 and a small caliber of 1:10.

　　3、 Installation and maintenance:

　　1. Adopting flange connection, threaded connection and clamping type;

　　2. The direction of liquid flow during installation should be consistent with the direction indicated by the arrow on the sensor housing, and the upstream straight pipe section should be ≥ 6DS, and the downstream straight pipe section should be ≥ 5DS (DS is the measured inner diameter of the tested pipeline);

　　3. Sensors should be kept away from external magnetic fields. If unavoidable, necessary measures should be taken;

　　4. In order to avoid affecting the normal transportation of liquids during maintenance, bypass pipelines should be installed outside the straight pipe sections at both ends of the sensor;

　　5. When installing sensors outdoors, please ensure that the amplifier plug is waterproofed;

　　6. The wiring between sensors and display instruments should be selected based on the power supply of the amplifier.
