HD2013 Rain gauge with tipping bucket Delta Ohm (GHM) Vietnam

The HD2013 is a reliable and sturdy tipping 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 heating 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, 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 Delta OHM or by a pulse counter.
The rain gauge is available with optional analog output (HD2013UA) at choice between 4…20 mA or 0…10 Vdc (to be specified when ordering) or with optional SDI-12 digital output (HD2013UD).
