The only compact professional 200 cm² ultra-low-power Class-A rain gauge capable of high-precision rain measurement without regular maintenance. It is designed for mass sensor deployments in smart cities and smart agriculture. Its high accuracy and repeatability of measurement make it suitable for replacing aging WMO and NWS compliant meteorological equipment.
MeteoRain® 200 Compact uses a self-balancing measuring principle. It offers high resistance to error producting effects as found in most rain gauges. These include soiling of the internal measuring mechanism, mechanical friction, residual water remaining in the measuring spoon from previous rain event, and debris. Additionally, MeteoRain® offers high resistance to vibrations and non-level mounting.
Self-balancing, self-emptying magnetic tipping bucket technology to ensure uninterrupted measurement of precipitation regardless of amount and intensity. It measures rain by means of a standardized orifice funnel which collects water into the precision measuring mechanism. The mechanism offers more consistent long-term response than any other standard tipping-bucket rain gauge
Rain gauges are individually tested and use high quality sealed reed switches. Electronics are protected against salt spray, water, frost and heat by a weather-‐resistant coating.
- Simplicity and reliability
- Multiple mounting options
- Easy to maintain and simple to clean with a removable funnel sieve/sift
- Robust and impact resistant funnel and housing
- Errors from non-level mounting are minimized with the self-balancing design
- Easy adjustment and recalibration of internal measuring mechanism
- Protection of measuring mechanism from contact during wire connections
- High-speed (0.13 s) self-emptying mechanism for high precipitation rate accuracy
- High-dynamic range up to 10 mm/minute (50 tips/minute) rain rates
- Bird-spikes are available. Leaf fence is not required due to self-cleaning funnel.
- Low-profile funnel for easy cleaning with a sharp edge for accuracy
