Product Introduction
Array radar flowmeter, consisting of 1 radar flowmeter, N radar flow meters, and a flow host, is an integrated flow monitoring device based on Doppler microwave technology that can continuously measure water level, multiple sets of flow rates, and flow rates. The system combines the collected values of water level and multiple flow velocities with the flow algorithm of the hydrodynamic model to achieve the calculation of cross-sectional flow and cumulative flow. Due to its use of multiple velocity measurement techniques, it is suitable for flow measurement in many large channels and relatively wide river channels.
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 multiple channels or river types, such as rectangular and trapezoidal flow accumulation.
※ 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.
※ Multiple sets of flow velocity measurement techniques are used to calculate the average flow velocity of the cross-section more accurately.
