Hydreka's PL2 range of rain gauges are designed for the automatic measurement of rain, melted snow or hail.
The instrument is based on a tipping bucket technology calibrated for different quantities of precipitation; the output signal generated by the rain gauge when the full bucket tips can be connected to an acquisition system, stand-alone data logger or traditional PLC, which ensures the logging and calculation of precipitation volumes.
Robust and easy to use, the PL2 is available with 2 opening areas (200 and 400 cm2) and for 4 bucket tipping frequencies (0.1 mm, 0.2 mm, 0.254 mm and 0.5 mm).
It can be supplied with a heating option to maintain operation during winter.

Applications
- Standard meteorological monitoring, Flood prevention, Climatological studies, etc.
- Diagnosis of sewerage networks within the framework of flow measurement campaigns
- Data collection of rain and snowmelt periods for the analysis of wastewater overflow events
- Stormwater intrusion monitoring in sewer systems
- Monitoring of leachate production and groundwater contamination risks
- Follow-up studies of source water quality (evolution of turbidity...)
- Support for agricultural operations
Main benefits
- Robust design
- Flexible and modular solution
- Accuracy, sensitivity
- Coupling to a data logger makes it possible to measure the evolution of the precipitation intensity over time in addition to the simple volume measurements.
- Possibility of integration into an intelligent measurement chain combining stand-alone battery data loggers and Hydreka's management tools, for example in a sewerage network:
— Rain gauge, with volume measurement and alarm management
— Water level sensor, with flow calculation integrated in the data logger
— Sampler, controlled directly by the data logger on configurable thresholds
