Frequently asked questions
How does a tipping bucket rain gauge work?+
Rain funnels into a small bucket mechanism; each time a bucket fills to a fixed volume it tips, triggering a reed switch pulse. Counting pulses over time gives rainfall depth.
What is the resolution of the SL3-1?+
0.1 mm per tip, over a measurement range of 0-4 mm/min.
What is the funnel material and size?+
Stainless steel, Ø200 mm diameter.
What output does the SL3-1 provide?+
A simple two-wire on/off pulse signal via reed switch, rather than a digital bus interface.
