The HD2013 is a reliable and sturdy tipping bucket rain gauge, built entirely from corrosion resistant materials in order to guarantee reliability, accuracy and durability.and to withstand even extreme conditions. Depending on the environment where the rain gauge is placed, there is a choice between heated or non-heated version (HD2013R).
The principle of a tipping bucket rain gauge is simple: depending on the quantity of rainfall, the tipping bucket mechanism fills and empties. Every tipping action operates a reed contact: in this way counting the quantity of the rainfall. This means that the tipping bucket has one enormous advantage: it needs no power supply to operate. Power supply is only a necessity when circumstances demand heating because of low environmental temperatures.
Reading the number of counts, in other words reading the rainfall, can be done locally by using a local (battery operated) datalogger such as the HD2013-DB. But it is also possible to communicate directly the results through one of our dataloggers of the HD33 series. The built-in 4G/3G/GPRS modem makes it easy to upload the data directly to one of our cloud applications or to your own secured server.
HD2013 is available as well with optional analog output (HD2013UA) at choice between 4…20 mA or 0…10 Vdc (to be specified when placing the order) or with optional SDI-12 digital output (HD2013UD). When ordering, the rain gauge is completely setup to be used.
