Zetian - Model ZDMFA-01 -Ultrasonic Doppler Flow Meter
Based on the Doppler effect, the ZDMFA-01 Ultrasonic Doppler Flow Meter can simultaneously monitor the flow rate, velocity, water level, water temperature and other parameters with millimeter-level accuracy, suitable for fluid flow measurement in a variety of environments. In a one-package structure, the product is easy to operate, waterproof and pressure resistant, not affected by external environments and has a low failure rate. Therefore, the product meets the user's requirements for high accuracy and high stability.Cross-sectional velocity measurement: streamlined compact structure design for less impact on the water cross-section flow pattern;
High measurement accuracy: Doppler shift algorithm ensures stable measurement results and accurate velocity resolution down to the millimeter level;
Diverse functions: in addition to measuring the flow rate, it can also detect the depth of water level and water temperature in real time;
Low power consumption design: embedded hardware and software integration in a miniaturized package with low power consumption;
Wide range of application scenarios: can be applied to occasions where the full pipe flow or partially full pipe flow is greater than 20mg/L, as well as river, channel flow measurement;
High protection level: meet IP68 protection level, can be applied to a variety of different occasions.
