Tipping Bucket Rain Gauge – Automatic Rainfall Measurement Sensor for Weather and Hydrological Monitoring

This instrument serves as a primary sensor for precipitation measurement. Its core component—the tipping bucket—features a 3D streamlined design that ensures smoother water discharge while offering self-cleaning capabilities and ease of maintenance. It supports both pulse and RS-485 signal outputs, allowing for direct rainfall readings without the need for secondary calculations, making it simple and convenient to use. The instrument comprises a housing, filter, rain collector, funnel, tipping bucket, terminal block, support legs, reed switch, control box, and base. The tipping bucket utilizes an integrated positioning structure for its shaft sleeve, with the bucket mounted on bearings via its shaft. As the internal components are fully assembled prior to shipment, no on-site internal assembly is required, thereby simplifying the installation process.
