Weighing Principle Precipitation GaugeMETEOROLOGY General Description HyQuest Solutions' PreciBal 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. PreciBal is a low power device even during cold winter times, as the heating is controlled by a combination of temperature settings and rain events. PreciBal 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 PreciBal versions are on hand of 200, 400 and 500 cm2. The following readings are available via serial interfaces and via the PreciBal app (see flipside): ■ One-minute intensity ■ Total sum of precipitation ■ Rain duration The tried and proven design of the PreciBal 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, PreciBal has no moving parts. Rain and snow are weighed using a strain-gauge bridge. The PreciBal excels by means of coupling a simple mechanical construction with advanced weight measuring cells and sophisticated firmware. PreciBal is designed as a low-maintenance device: large aperture to ensure inflow, load cell and simple mechanical design. The advanced high-resolution load cell turns the PreciBal into a balance determining rain mass rather than volume assuring a higher accuracy. Low power consumption, low maintenance, high accuracy and sophisticated algorithms ensure reduced operational costs and better data. In addition, the PreciBal's USB interface allows quick field checks of the device. Applications The PreciBal is especially suitable for ■ Classical Meteorology and Climatology ■ Hydrometeorology ■ Environmental, Hydrological and Air Quality Monitoring Features ■ Modern weighing precipitation gauge, incl. app for data viewing, set-up, diagnostics, etc. (see flipside) ■ Compensation of all major error sources ■ Hardly any maintenance ■ Autodiagnostic and self-check ■ Thermo- and event-controlled orifice heating ■ Various types of data output ■ In-situ functional test via USB port ■ Local and remote diagnostics HYQUEST SOLUTIONS
