Product Introduction
HD-RDF420 series radar flowmeter is a Doppler microwave technology based on independent research and development of Chongqing Haidun Technology Co., Ltd. can continuously measure the water level, flow rate and flow of the integrated flow monitoring equipment. The internal integration of radar water level measurement module and radar flow rate measurement module in the device combines the collected values of water level and flow rate with the flow algorithm of hydrodynamic model to realize the calculation of cross-section flow rate and cumulative flow rate, which is applicable to the flow measurement of rectangular, trapezoidal, U-shape and circular nullahs or culverts in reservoirs, rivers, farmland irrigation areas, and water resources of water administration.
Functional features
※ Microwave radar is not affected by temperature and humidity, pressure, wind and rain or other meteorological environmental conditions, can work stably in all-weather.
※ Measurement is not affected by floating objects in the water, sediment, air bubbles and large changes in water level, high accuracy.
※ Supports flow accumulation for a variety of channel types, such as rectangular, trapezoidal, U-shaped and circular channels.
※ Supports dormancy function, which can greatly reduce power consumption according to the usage scenario, and is suitable for field solar-powered occasions.
※ Simultaneous output of air height, water level, flow rate, instantaneous flow rate, cumulative flow rate and other measurement data.
※ Support RS485 communication interface, MODBUS RTU communication protocol, can also be customized protocol.
※ With data saving function, it can save the setting parameters and cumulative flow value in case of long-term power failure.
※ Non-contact measurement, no pollution, no loss, long service life.
※ Adopting linear frequency modulated continuous wave (FMCW) mode, it can accurately measure the water level and flow rate in the measuring range.
