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

To ensure accurate measurements even with low temperature climatic conditions or during and after precipitations of snow, a version with heating system (HD2015R), automatically activated around +4 °C, has been developed to prevent snow deposits and ice formations.

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 or by a pulse counter.

A removable filter for periodic cleaning and maintenance is inserted in the water collector cone so as to prevent leaves or other elements blocking the end of the hole.

For a better water flow, the collecting cone is treated with a non-stick coating. The version with heating option HD2015R works with 12 Vdc or 24 Vdc direct voltage (to be specified at the time of order). The heating system is activated around +4 °C.

When submitting your order, it is possible to request a bird dissuader, made of eight 3 mm diameter spikes, 60 mm in height, to be installed on the rain gauge.
