The HD2015 is a reliable and sturdy bucket rain gauge, entirely constructed of corrosion-resistant materials in order to guarantee its durability. A system that automatically activates around +4 °C to prevent snow deposits and ice formations has been developed to ensure accurate measurements even in low-temperature climatic conditions or during and after snow precipitations.

The rain gauge is formed by a metal base on which a tipping bucket is set. The rain collector cone, fixed to the aluminium cylinder, channels the water inside the tipping bucket: once the predefined level is reached, the calibrated bucked rotates under the action of its own weight, discharging the water. During the rotation phase, the normally closed reed contact opens for a fraction of a second, sending an impulse to the counter.

The quantity of rainfall measured is based on the count of the number of times the bucket is emptied; the reed contacts, normally closed, open at the moment of the rotation between one bucket’s section and the other. The number of impulses can be detected and recorded by a data logger such as the HD2013-DB or by a pulse counter. However, the results can also be communicated directly via one of our HD33 series data loggers. The built-in 4G/3G/GPRS modem makes it easy to upload the data directly to one of our cloud applications or to your own secured server.

When you order, the rain gauge is fully assembled and ready to use. Easy to install, with adjustable feet and a leveling device integrated. Bird spikes and accessories for raised mounting are available. A removable filter for periodic cleaning and maintenance is inserted in the water collector cone so as to prevent leaves or other elements from blocking the end of the hole.
