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 by using anti-freeze agent to decrease the freezing point of collected water. The optional heating is controlled by a combination of temperature settings and solid precipitation events to avoid snow capping and ice accretion at extreme environmental conditions.
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. The result is outstanding measuring performance in terms of accuracy, long term calibration for real-time precipitation monitoring at entire intensity range up to 2000 mm/h.
The compact design allows for easy installation. Due to its low power consumption PreciBal is ideal for remote stations powered by battery or a small solar panel. Two different versions regarding the bucket orifice (200 / 314 cm2) and collecting size (1.500 / 1.000 mm) are available. Processed precipitation data (one-minute intensity, various cumulative precipitation data, weight, temperature) are available via serial interfaces and via the PreciBal app.
PreciBal with its solid state design without any moving part measures liquid and solid precipitation by its factory life time calibrated and adjusted load cell at highest standards and performance on accuracy and reliability. Low power consumption, low maintenance and high accuracy ensure reduced operational costs, less staff deployment in the field, better data and high data availability.
In addition to HyQuest Solutions’ data loggers, PreciBal is compatible with other data loggers and ideal for deployment at new sites or expansion of precipitation monitoring networks.
