For recording any kind of precipitation (rain) with its intensity in the nature usually tipping bucket precipitation gauges and samplers are used. If precipitation has to be measured also in winter with temperatures below the freezing point, the measuring instrument has to be equipped with a heating. PRECIPITATION GAUGE USING THE WEIGHING PRINCIPLE NIWA-215/415 NIWA-215/415 is an innovative high-quality precipitation gauge using the weighing principle for measuring liquid, solid and mixed precipitation within a wide temperature range. It conforms to the most stringent requirements of the WMO. NIWA-215/415 is a low power device even during cold winter times, as the heating is controlled by a combination of temperature settings and rain events NIWA-215/415 achieves very high levels of accuracy by means of correcting the data to eliminate the influence of wind vibration, particles, unrealistic weight variations, evaporation, and temperature fluctuation. Regarding the bucket orifice different NIWA-215/415versions are on hand of 200 and 400cm2. The following readings are available via serial interfaces: One-minute intensity Total sum of precipitation Rain duration The tried and proven design of the NIWA-215/415 ensures long-term accurate and repeatable results. It is manufactured from high quality, durable materials ensuring longterm stability in the harshest of environments. Above that, NIWA-215/415 has no moving parts. Rain and snow are weighed using a strain-gauge bridge.
