Details

To truly understand the hydraulics of your collection system, including pinpointing I&I trouble areas, accurately monitoring and analyzing the effects of rainfall is imperative. The Sigma Rain Gauge Tipping Bucket is a simple yet highly accurate approach to capture rain event data and create a more accurate profile of your system. And when you pair it with a wireless Hach FL900 Series Flow Logger, you won't even have to go out into the elements to know exactly what's going on, at every monitoring location. Instead you can simply view your rain data in real-time, right from your desktop. Or laptop. Or tablet. Or phone.

Built to National Weather Service standards, the Sigma Rain Gauge accurately measures rainfall in 0.01" increments. And installation, using the gauge's built-in bubble level and innovative, spring-loaded base plate, is as easy as it gets. Plus, with a stainless steel screen to prevent leaves or other wind-blown debris from plugging the collection funnel, required maintenance visits are few and far between

Standard cable length for use with the FL900 Flow Logger is 100 feet

Standard cable length for use with the Sigma 950 Flow Meter is 25 feet
