brief introduction
SI-3L ™ The radio wave current meter radar sensor is a low-cost speed measurement radar sensor for measuring the surface flow velocity of water bodies, specifically designed to measure the flow velocity on the water surface, and the flow velocity information data can be obtained throughRS232Output through serial port. The design of the radar velocity sensor enables it to adapt to the measurement of surface velocity in various water bodies. You can also configure the radar sensor according to your specific requirements by configuring the software.
characteristic
Decatur SI-3LThe radar surface velocity sensor has applied a new generation of microstrip flat antenna, which has made a qualitative leap in technology: the new generation of microstrip flat antenna is on a thin dielectric substrate (such as polytetrafluoroethylene glass fiber laminate), with a metal thin film layer attached on one side as a grounding plate, and a metal patch of a certain shape (parallelogram or triangle) made by photolithography corrosion and other methods. The microstrip line and axis probe are used to feed the patch, which constitutes the microstrip flat antenna. Compared with the first generation conical microwave radar antenna, it has the following advantages:
Small size, light weight, low profile, able to conform to carriers (such as aircraft).
Diversified electrical performance. The maximum radiation direction of micro units with different designs can be adjusted within the range from edge radiation to end radiation. Easy to obtain various polarizations.
Easy to integrate. Can be integrated with active devices and circuits into a unified component
Good detection accuracy and minimal environmental impact.
The application of a single sensor three-dimensional beam sparse sub-band can achieve multi-purpose detection in reality.
Currently, there are onlyDecatur SI-3LThe series of water flow surface velocity sensors can respond to extremely low flow rates and measure0.1m/sThe low flow rate, fully automatic sensing of pitch and horizontal angle changes, and automatic compensation, this function is at the world's leading level.
