TR-4 Tipping Bucket Rain Gauge

Description

Texas Electronics TR-4 4" Tipping Bucket Rain Gauge low-cost rainfall sensor is a remote tipping bucket style rain gauge that measures liquid precipitation.

Texas Electronics Rain Gauge is a freestanding receptacle for measuring precipitation. Through an opening at the top of the device, rain is collected and then funneled to a mechanical device, called a tipping bucket. As water is collected, the tipping bucket fills to the point that it tips over, causing a momentary closure of a switch to incrementally measure rainfall accumulation. This action empties the bucket in preparation for additional measurement. Water discharged by the tipping bucket passes out of the rain gauge with no need for emptying.

TR-4 was designed to meet the need for a rugged and reliable rain gauge tipping bucket without the high accuracy of a research grade sensor, or the associated cost.
