TR-525I Rain Gauge Tipping Bucket

The Texas Electronics, Inc. TR-525I Rainfall Sensor with 6″ diameter funnel is a remote tipping bucket style rain gauge that measures liquid precipitation.

The 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.

The TR-525I is a rugged and reliable rain gauge that delivers high accuracy at a low cost.

Hach Rain Gauge

Diverse and Reliable Measuring

Built to National Weather Service standards, the gauge accurately measures rainfall in 0.01” increments. The tipping bucket mechanism tips with every 0.01” of rainfall, producing a momentary contact closure with each movement. A stainless steel funnel screen prevents plugging from leaves and other wind-blown debris. The removable funnel permits viewing of a built-in bubble level, with an innovative spring loaded base plate providing an easy, convenient means to level the gauge. A hole in each corner of the base plate permits a secure, anchored installation.

Principle of Operation

The 8” diameter funnel directs rainwater into a “tipping bucket”, which is divided vertically into two halves. When 0.01” of rainfall fills one side of the bucket, the bucket tips, spilling the water through the bottom of the rain gauge. The other side of the bucket is then positioned under the funnel.

The bucket alternates tips with each 0.01” of rainfall. With each tip, a magnet, mounted to the bucket, activates a sealed, magnetic reed (proximity) switch, producing a momentary contact closure. Data is logged at user selectable time intervals using Hach FL900 series logger or Sigma 950 Flowmeter.
