Concealed double Venturi tube, nominal diameter of circular section pipeline: DN=300mm~6000mm, width x height of rectangular section pipeline: WxH (mm)=300x300~6000x6000, and other geometric surface pipelines with the same nominal diameter DN and varying width and height. Nominal pressure: PN ≤ 2.5MPa, determined by working temperature and material; differential pressure value: (0~100) kPa, repeated measurement error (stability): ± 10Pa.
22. The wing wind measurement device is particularly suitable for measuring large-caliber airflow, with stable measurement, high sensitivity, pressure loss offset, and high accuracy.
23. The design of the wind measurement device includes a reverse blowing interface and a dust discharge device, which is beneficial for product maintenance and increases product output
Reliability.
24. Advanced and sophisticated processing and testing technology greatly improves product accuracy and stability.
25. Mature throttling components are integrated with advanced electronic technology to create an intelligent integrated flow measurement device with on-site flow display and multiple signal outputs (4-20mA, pulse, with HART protocol).
26. Low-power circuit design reduces energy consumption, increases system stability and reliability. The integrated system has a battery power supply and an external 24VDC selection, which is convenient for installation and use.      

Main selling points:
1. Standardization is mature and does not require actual flow calibration: it complies with GB/T2624 and ISO5167 standards. Standard throttling components can be directly used for measurement after being processed according to specifications, supporting trade settlement and measurement traceability.
2. No moving parts, durable and stable: pure mechanical throttling components, no rotating/sensing elements, high temperature and high pressure resistance, reliable long-term operation, long service life, low basic maintenance.
3. Wide range of medium adaptation: It can measure gases, vapors, and liquids, support single-phase fluids, and some models can adapt to dirty media containing small amounts of impurities. The pipe diameter coverage is extensive.
4. Low overall cost, flexible matching: simple structure, economical cost, can be matched with any brand of differential pressure transmitter; Multiple types such as orifice plate, nozzle, Venturi, V-cone, etc. can be selected according to the working conditions.
