Product Introduction
The HD-RDF420 series radar flowmeter is an integrated flow monitoring equipment independently developed by Chongqing Haydun Technology Co., Ltd. based on Doppler microwave technology, which can sustainably measure water level, flow rate, and flow rate. The device integrates radar water level measurement module and radar flow velocity measurement module internally, combining the collected values of water level and flow velocity with the flow algorithm of the hydrodynamic model to achieve the calculation of cross-sectional flow and cumulative flow. It is suitable for flow measurement of rectangular, trapezoidal and other open channels or culverts such as reservoirs, rivers, farmland irrigation areas, water resources, etc.
Functional characteristics
※ The microwave radar is not affected by temperature, humidity, pressure, wind and rain, or other meteorological environmental conditions, and can operate stably all day long.
※ The measurement is not affected by floating objects, sediment, bubbles, and significant changes in water level, with high accuracy.
※ Support flow accumulation for multiple channel types, such as rectangular and trapezoidal channels.
※ Supports sleep function and can significantly reduce power consumption according to usage scenarios, suitable for outdoor solar power supply scenarios.
※ It can simultaneously output measurement data such as air height, water level, flow rate, instantaneous flow rate, cumulative flow rate, etc.
※ Supports RS485 communication interface, MODBUS RTU communication protocol, and can also customize the protocol.
※ It has a data saving function, which can save set parameters and accumulated flow values in the event of long-term power outages.
※ Non contact measurement, no pollution, no loss, and long service life.
※ Using linear frequency modulation continuous wave (FMCW) mode, it can accurately measure water level and flow velocity within the measurement range.
