Description :

　　This product has the characteristics of simple structure, high measurement accuracy, long service life, easy operation, and easy maintenance. Widely used in metallurgy, chemical industry, petroleum, urban construction, environmental protection, food and other fields.

　　1、 Technical parameters:

　　Measurement caliber: Pipeline type: DN0.5~DN600;

　　Accuracy level: ± 0.2%, ± 0.5%, ± 1.0%;

　　Environmental temperature: -20 ℃~+50 ℃;

　　Medium temperature: Measurement liquid: -20 ℃~+120 ℃;

　　Nominal pressure: 1.6 Mpa, 2.5 Mpa, 6.4 Mpa, 25 Mpa;

　　Explosion proof grade: ExdIIBT4;

　　Connection methods: threaded connection, clamp connection, flange connection, plug-in connection, etc;

　　Output function: Pulse output, 4-20mA two-wire current output, with RS485 communication interface.

　　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;

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

　　3、 Precautions for use:

　　When using, the tested liquid should be kept clean and free of impurities such as fibers and particles.

　　At the beginning of use, the sensor should be slowly filled with liquid before opening the outlet valve (which should be installed at the back of the flowmeter). It is strictly prohibited for the sensor to be impacted by high-speed fluid when it is in a liquid free state.

　　The maintenance cycle of sensors is generally six months. During maintenance and cleaning, please be careful not to damage the parts inside the measuring chamber, especially the impeller. Please pay attention to the position relationship between the guide components and the impeller during assembly.

　　When the sensor is not in use, the internal liquid should be cleaned, dried, and protective covers should be added at both ends of the sensor to prevent dust and dirt from entering, and then stored in a dry place. (This is very important)

　　The matched filter shall be cleaned regularly, and the internal liquid shall be cleaned when not in use. Like the sensor, it shall be sealed with dust cover and stored in a dry place.

　　The transmission cable of the sensor can be laid overhead or buried underground (iron pipes should be covered when buried underground)

　　Before installing the sensor, connect the wires to the display instrument or oscilloscope, turn on the power, blow or manually turn the impeller to quickly rotate and observe if there is any display. When there is a display, install the sensor. If there is no display, check the relevant parts and eliminate the fault.
