RainVUE™ 20Rainfall sensors are an ideal choice for many hydrological and meteorological applications, and are highly suitable for use in weather stations, flood warning systems, and other applications. andRainVUE™Like other products in the series,RainVUE™ 20Also supportiveSDI-12A tipping bucket rain sensor with signal output. The advanced algorithms and data processing functions built into the sensor can compensate for measurement errors caused by heavy precipitation and provide accurate measurements of precipitation amount and intensity.

RainVUE20 Rain GaugeFeaturing a powder coated aluminum funnel that conforms to aerodynamic shapes, it is sturdy, durable, and minimizes liquid settling due to wind loss.

The cable configuration of this sensor is flexible, and users can choose from a series of set cable lengths or customize the cable length.

Advantages and Characteristics

uAdjustable installation components simplify horizontal adjustment

Details

RainVUE™ 20The rain sensor collects rainwater through a stainless steel filter screen, which can also filter out debris at the same time. Rainwater flows into the tipping bucket through the filter screen. When the first tipping bucket is filled with water to a fixed calibration height, the internal tipping bucket assembly will rotate and tilt around the precision pivot bearing. Then the balance arm moves the second tipping bucket below the funnel. When the tipping bucket tilts, the magnet connected to the balance arm will drive the magnetic spring switch, forming a pulse signal.

RainVUE™ 20The aerodynamic design of the rain sensor can prevent wind from carrying rainwater away from the collector. Traditional cylindrical rain sensors, due to the influence of wind, can bring up to20%Measurement error.RainVUE™ 20It also includes a microprocessor that can calibrate precipitation intensity and outputSDI-12signal
