Delta Ohm HD2013 Rain Gauge with Tipping Bucket, Area 400 cm2

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 accuratemeasurement 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 raincollector cone, fixed to the aluminium cylinder, channels the water inside the tippingbucket: once the predefined level is reached, the calibrated bucked rotates under theaction 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 thecounter.

The quantity of rainfall measured is based on the count of the number of times thebucket 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.

The rain gauge is available with optional analog output at choice between 4…20 mA(HD2013…A…) or 0…10 Vdc (HD2013…V…) or with optional SDI-12 digital output(HD2013…S…).The version with 4…20 mA output and the version with SDI-12 output require 7…30 Vdcpower supply. The version with 0…10 Vdc output requires 13…30 Vdc power supply. Theversions with analog or SDI-12 output are equipped with a backup battery that allowsmaintaining the rainfall information even after short power supply outages (at least 10seconds for the versions with analog output, approx. 5 minutes for the version withSDI-12 output).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-adherent product.In the version with heating HD2013…R…, the heating circuit operates with 12 Vdc or24 Vdc direct voltage (to be specified when ordering) and absorbs about 165W.Heating is activated around +4 °C.When submitting your order, upon request a bird dissuader, made of eight 3 mmdiameter spikes, 60 mm in height, can be installed on the rain gauge. 

Options:
Bird spikes
-Heater: power voltage 12 Vdc or 24 Vdc (to be specified when ordering) ± 10% / power absorption 165 W.

-Contact output and analog output: at choice between 4...20 mA or 0...10 Vdc (to be specified when ordering). The contact output and the analog output are alternatives and the raing gauge is factory-configured with analog output. Configurable measuring range (the analog output full scale, 20 mA or 10 V, can be associated to different rainfall values). Power supply 7...30 Vdc. RL max = 50 • (Vcc – 7) Ω for 4...20 mA output. Measure remote reset command.

-Contact output and SDI-12 digital output. The contact output and the SDI-12 output are alternatives, and the rain gauge is factory-configured with SDI-12 output. Power supply 7...30 Vdc. Measure remote reset command.
