Millimeter-Wave Radar
YRD02-WB
Radar Flowmeter (narrow channel/underground network)
Product Overview
The YRD02-WB radar flowmeter integrates a 24 GHz velocity radar, a 120 GHz low-blind-zone level radar, a flow accumulation module and Bluetooth, designed for narrow irrigation channels and underground pipe networks. Level measurement starts from only 0.02 m with ±1 mm accuracy; results are transmitted via RS485 or Bluetooth.
