Rain Gauge

The HD2013 is a reliable and sturdy bucket rain gauge, built entirely from corrosion resistant materials in order to guarantee its durability. So as to ensure
accurate measurement even with low temperature climatic conditions or during
and after precipitations of snow, a version with a heater which is automatically
activated around +4°C has been developed so that snow deposits and ice formations are prevented.

The rain gauge is formed by a metal base on which a tipping bucket is set. The
rain collector cone, fi xed to the aluminium cylinder, channels the water inside the
tipping bucket: once the predefi ned level is reached, the calibrated bucked rotates
under the action of its own weight, discharging the water. During the rotation
phase, the usually 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, usually 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 datalogger such as the HD2013-D Delta Ohm or
by a pulse counter.

A removable fi lter 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

For better water flow, the collector cone is treated with a teflon® paint.
