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 springloaded
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.
