tipping bucket rain gauge resolution 0.2 mm typical

A tipping bucket rain gauge works by funnelling rain into a seesaw-like bucket mechanism. Each tip triggers a magnetic switch, sending a pulse that logging equipment interprets as rainfall depth. With a 0.2 mm typical resolution, the bucket size is engineered so that 0.2 mm of collected water (over the funnel area) causes the tip. Kingmach produces these gauges with stainless steel internal components and UV-stabilized housings, aimed at multi-year deployment. The funnel mesh keeps out leaves but wants occasional cleaning—the Achilles' heel of any tipping bucket design. In terms of compatibility, the pulse output works with most data acquisition systems: Campbell Scientific loggers, generic PLCs, GSM remote monitors, you name it. Some customers ask for adjustable resolution; while the bucket mechanically fixes the volume, you can change the funnel diameter to tweak effective resolution. Kingmach's customization service can provide that if your project demands, say, 0.1 mm mapping on a smaller catch area. Typical applications include landslide monitoring where light rain infiltration matters, agricultural water balance studies, and urban drainage network triggers. The standard model ships with a bubble level and screw anchors for concrete plinths. If you're comparing, remember that a 0.2 mm gauge generates half the pulses of a 0.1 mm unit for the same storm, which extends logger memory and battery life—not trivial in off-grid installations.
