The rain gauge is formed by a
metal base on which a tipping bucket is set.
The rain collector cone, fixed to the aluminum 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 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
limes the bucket is emptied:
the reed contacts, usually dosed, 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 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 better water flow, the collector cone is treated with a teflon® paint.
The HD2013R, the version with a heater, operates using either 12Vdc or 24Vdc
voltage and uses about 35W. Heating is activated around +4"C. When
submitting your order, upon request a bird dissuader. made of 8 3mm-diameler
spikes, GO mm m height, can be installed on the rain gauge.
