Rain Gauge Sensor

Designed to meet National Weather Service standards, the Rain Gauge is equipped with a stainless steel funnel screen that effectively prevents clogging from leaves and debris carried by the wind, ensuring consistent and accurate measurements. For easy maintenance, the removable funnel allows for quick cleaning, while a built-in bubble level, visible through the funnel, ensures accurate placement. The innovative spring-loaded base plate simplifies the leveling process, making setup straightforward and reliable. Additionally, the base plate features holes at each corner, allowing for secure, anchored installation, ensuring the gauge remains stable even in adverse weather conditions.

With an 8-inch diameter funnel directing rainfall into a vertically divided tipping bucket, this Rain Gauge offers a highly efficient design. When one side of the bucket fills with 0.01” of rain, it tips, emptying the water through the bottom and positioning the other side under the funnel for continuous measurement. Each tip activates a magnet mounted on the bucket, which in turn triggers a sealed magnetic reed switch to produce a momentary contact closure. This precise data is logged at user-selectable intervals using compatible devices such as the FL900 Flow Logger or the FL1500 Flow Meter. This rain gauge combines durability, accuracy, and ease of use, making it an essential tool for accurate rainfall measurement in a variety of environments.

• Diverse and Reliable Measuring
• Tipping Bucket Operation
• Convenient Features
• Simple Installation

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.

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 the FL900 and FL1500 Series Flow Loggers.
