High precision weighing rain gauge

High precision weighing rain gauge complies with WMO 306 No.8 rainfall measurement standard

High precision weighing rain gauge High precision weighing rain gauge is used to measure rainfall intensity at the same time.

Not affected by external climate

gravimetric measurement

Can measure any solid/liquid and mixed precipitation

No mechanics and no maintenance issues of a tipping bucket rain gauge

Measures any type of rainfall

Capable of collecting data throughout the year

Simple and convenient installation, maintenance-free

Lifetime calibrated weighing system, no periodic calibration required

Especially suitable for heavy rain/snowfall measurements

Real-time rain intensity range up to 3000 mm/h

It has its own heating device and a variety of heating methods to choose from. It can also work normally under extremely harsh conditions such as heavy snow and frost.

Comes with temperature and wind compensation

Operating temperature range from -40 – 60 degrees

Can be powered by solar energy and can be used for field measurements

Two specifications are used in humid and dry areas respectively.

USB interface for setting, simple and convenient

RS485, SDI12 and pulse output, flexible and versatile

High precision weighing rain gauge measuring principle

Pluvio2 uses a high-precision electronic weighing principle for precipitation measurement. High-precision weight sensor can measure rainfall intensity at the same time, and the internal electronic balance system

It can also measure the evaporation of rainwater with high accuracy. It can be equipped with an inverted siphon automatic drainage system and heating device, which is not affected by external weather changes. Low power consumption intelligent transmission

It can work normally when powered by solar energy or 12V battery.

In winter, antifreeze can be added to the rain barrel to measure snowfall. Snow falling in the rain barrel will melt directly without accumulation or freezing.

The instrument comes with wind compensation and precipitation detection functions, so it can be used normally in areas with strong winds. There is also a windshield accessory that can better adapt to areas with heavy winds and sand such as the northwest.
