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.

It is mainly used for on-line automatic monitoring of the flow of urban drainage pipe network (rainwater pipe,
sewage pipe, rainwater and sewage combined pipe), rivers and channels, which provides accurate flow data for the
simulation and validation of the flow of drainage pipe network, simulation of waterlogging, maintenance of
drainage pipe network, hydrological monitoring of rivers, and informatization of irrigation districts.
