Geonica - Model DataRain-4000 -Electronic Weighing Rain Gauge
Model DataRain-4000 is a new professional precipitation sensor designed by GEONICA according to the requirements of the WMO (World Meteorological Organization). This patented precipitation sensor combines a very accurate measurement principle (electronic weighing) and an automatic emptying system, in such a way to allow unlimited (maintenance-free) very accurate operation, from a minimum detectable precipitation intensity as low as 0.02 mm/h, up to a very high, constant and permanent precipitation intensity of 1200 mm/h (200 cm2 collecting area version) or 800 mm/h (300 cm2 collecting area version). Due to its principle of operation, the sensor provides a permanent calibration, and its resolution is also maintained in the whole measuring range from 0.02 mm/h to full range (800 mm/h for the 300 cm2 version or 1200 mm/h for the 200 cm2 version).
The upper measuring range of the smart precipitation gauge DataRain-4000 largely exceeds natural phenomena. On the other hand, and also due to its very high resolution, the standard collecting area of 200 cm2 is more than enough for measuring very low precipitation amounts where higher sensitivity/resolution is required (0.02 mm of precipitation). For applications requiring a higher resolution (0.013 mm) the version with a collecting area of 300 cm2 is available.
Worldwide Smart Precipitation Sensor
Smart precipitation sensor featuring worldwide measuring accuracy, including monsoon, tropical, and cold regions.
Direct Replacement of Tipping-Bucket Precipitation Gauges:
DataRain-4000 incorporates a built-in solid state switch output, software configurable, for: 0.05, 0.1, 0.2 and 0.5 mm per pulse, or any other resolution, solving definitively the limited accuracy and measuring range offered by the classical mechanical tipping-bucket precipitation gauges.
Maintenance Free
NOT required (unlimited operation by automatic emptying procedure). This reduces maintenance tasks and avoids periodic manual draining work.
Configuration Interface and Firmware Update in the Field
The DataRain-4000 includes an interface to setup the internal configuration according to each project requirements: serial baudrate, pulse resolution, identifier, etc. This interface is accessible through the serial port. It also allows the internal program to be updated.
Hydrophobic
An optional hydrophobic layer can be applied to the collection funnel to ensure that each drop of precipitation is measured.
Smart Filter Algorithm Against Extreme Wind
Algorithm settings customizable to adapt product operation to strong wind environments, avoiding unwanted incorrect precipitation measurements.
Precipitation and Diagnosis Information
The DataRain-4000 sensor supplies accumulated amount of precipitation and intensity of precipitation. In addition, it supplies some extra internal status data. This information is bit-coded forming a 16-bit code updated every 1 second. The Sensor Status Coded Data provides information about the internal hardware status, the resets in the last minute, the internal sampling rate, status of automatic emptying system, etc.
Protection Filters
- The stainless steel protection cartridge filter can be installed inside the collection funnel to filter out leaves, etc.
- The anti-insect drain filter prevents insects from entering through the drain orifice.
Heater
An optional automatic self-managed heater with built-in smart energy-efficient heating control has been designed and adapted to perform the melting process when measuring solid precipitation.
