Measuring free-flowing rain has always been a challenge in any environment for most municipals - until now.

The Rain Gauge Funnel Meter, a Hach Flow solution by McCrometer, is a precision rain gauge system that measures rainfall with 0.01” accuracy, utilizing a tipping bucket mechanism that triggers with each 0.01” of collected rain. Each tip of the bucket generates a momentary contact closure, allowing for precise data logging.

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.
