Weighing Rain Gauge
The HD2016 measures rainfall by weighing it continuously which provides an order of magnitude better resolution and accuracy than the tipping bucket method. As the rain is collected the load cell converts the weight of the water to volume and transmits the information through digital outputs. When the rain gauge reaches a certain level it automatically discharges the collected water. If it is raining at the time the discharge needs to occur, a second valve closes allowing the incoming water to be held in the top reservoir until the discharge is complete. As with the other rain gauges offered by Senseca, the HD2016 is designed to withstand extreme conditions.
