That is the basic thought behind the design of the HD2016. The corrosion resistant materials used and the absence of moving
parts guarantee a reduced maintenance and a long operating life. HD2016 rain gauge is built to withstand even extreme
conditions: a version with heating which is automatically activated below +4 °C has been developed so that snow deposits and
ice formations are prevented.
The sensor of the HD2016 is a load cell located at the base of the rainfall collecting reservoir. The signal of the load cell is
processed by the internal electronic board of the rain gauge in order to output the information on the rainfall. Thanks to the
multiplicity of outputs available, many acquisition systems / data loggers can be connected to the rain gauge. The rain gauge
is able to provide the total rainfall, the partial rainfall (from the last reset command or from the last reading command), the
average rainfall rate in the last minute and in the last hour. The measured rainfall is regularly saved into a non-volatile memory,
which retains the information even in case of power failure.
The automatic discharge of the rainfall collected allows using a compact and lightweight structure for the installation of the rain
gauge. If the discharge of the water collected takes place during a rainfall, a retention valve, located at the top of rain gauge,
temporarily holds the current rainfall, so to avoid losing the amount of rainfall that falls while discharging. The rain gauge is
equipped with sophisticated features that allow reducing the effects of wind, ensuring a better accuracy and stability of the
measurement. An NTC temperature sensor allows keeping under control the internal temperature of the instrument.
The rain gauge is factory calibrated and ready for use. A self-diagnostic system periodically checks the correct operation of
the instrument and reports any anomalies. Easy to install, adjustable feet (in standard deafult version) and leveling device
integrated. Bird spikes and accesories for raised mounting available.
