tipping bucket rain gauge

A tipping bucket rain gauge works on a simple mechanical principle: a seesaw bucket pivots each time a set amount of rain collects, triggering a magnetic switch that records a count. That simplicity is what keeps it common in weather stations, hydrology stations, landslide monitoring, and smart agriculture. But field conditions quickly expose weak welds, plastic warping under sun, or contacts that chatter in wind. At Kingmach, we put effort into the details that separate a gauge that needs weekly cleaning from one that runs a season without drift. Our standard models use stainless steel orifice rings and buckets, with an anodized or powder-coated aluminum housing to cut weight without inviting rust. The bearing system runs on sapphire pivots—common enough in the industry, but we pair them with an alignment jig during assembly to keep the bucket level under repeated loads. Calibration is done onsite before packing, with a known volume of water, not just a screw setting. Resolution options cover 0.1 mm, 0.2 mm, and 0.5 mm per tip, so you can choose what fits the data granularity your project needs. For heavy rainfall regions, we offer a syphon-controlled mechanism that buffers inflow, reducing undercount at intensities above 4 mm/min—again, nothing proprietary, but something cheaper units tend to skip. Because Kingmach is a geotechnical instrument manufacturer first, we support the rain gauge with data loggers, wireless transmitters, and mounting kits that talk to your existing monitoring network. Customization is part of our workflow: longer cable runs, special output protocols, or mounting brackets adapted to a specific tower. Our team provides technical documents and after-sales support through local distributors, so if a logger misreads a pulse count, you’re not stuck decoding it alone. The tipping bucket rain gauge isn’t the most complex sensor on a site, but when it fails, the missing data can throw off whole models. We aim to make that failure less likely, and easier to fix when it happens.
