Precipitation Sensors

Use a tipping bucket and “count” quantities? Or weigh quantities? Or measure fall velocity and analyze particle size? Each measurement method - whether tipping bucket, weight principle, laser or radar - differs in its application. Freedom from maintenance and fast response times play an important role in “present weather” applications.

        WS100 Radar Precipitation Sensor / Smart Disdrometer

        Absolutely maintenance-free and extremely fast measurement of precipitation type (Rain, snow, sleet, freezing rain, hail) and intensity, thanks to radar measurement technology. The smart radar rain sensor & present weather detector!

        The Lufft WS100 is our maintenance-free radar precipitation sensor. It recognizes the type and amount of precipitation from the first drop. The sensor is suitable for hard-to-reach places.

        • Rain/precipitation quantity, rain/precipitation type (Rain, snow, sleet, freezing rain, hail)
        • 24GHz Doppler radar
        • Very fast response time, maintenance-free measurement, present weather detection
        • RS-485 semi-duplex two-wire, SDI-12, pulse interface / UMB protocol, Modbus

        Rain Gauge WTB100

        Tipping Bucket Rain Gauge with Bounce-Free Reed Contact

        Tipping bucket rain gauge with bounce-free reed contact

        • Rain/precipitation quantity
        • Tipping bucket with bounce-free reed contact (normally closed)
        • Resolution can be switched from 0.2 to 0.5 with reduction ring, connectable to any WS-sensor without precipitation measurement
        • Impulse output (reed contact)

        OTT Parsivel² - Laser Weather Sensor

        Laser precipitation disdrometer measuring all precipitation types

        The OTT Parsivel² is a modern laser disdrometer for comprehensive measurement of all precipitation types. The Parsivel² captures both the size and speed of falling particles, classifying them into one of 32 separate size and velocity classes.

        • Precipitation type, intensity, drop size distribution, radar reflectivity
        • Laser (optical)
        • Simultaneous measurement of 32 classes for particle sizes and velocities
        • SDI-12 / RS-485, pulse

        OTT Pluvio² L – Weighing Rain Gauge

        All-weather, high accuracy rain gauge for continuous data collection

        The OTT Pluvio² L is an all-weather precipitation gauge that uses superior weight-based technology to measure the amount and intensity of rain, snow, and hail.

        • Cumulative precipitation, precipitation intensity, bucket content in real time and non real time
        • 12
        • All-weather precipitation gauge without moving parts according to WMO guide line No. 8
        • SDI-12 / RS-485, pulse

        OTT Pluvio² S

        Compact universal weighing precipitation gauge

        The OTT Pluvio² S compact weighing precipitation gauge measures liquid, solid and mixed precipitation with remarkable precision. It is virtually maintenance-free and fits on 2-inch pedestals.
