The RG20 rain gauge is connected to one of our portable and compact data logger LOG V4 which allows local data retrieval by radio communication, or it automatically sends them by GPRS to your your server in .CSV or compatible SCADA software such as Areal Topkapi, Lerne, Dev I/O, Floee, or our web monitoring platform

Tipping bucket rain gauge RG20

The sensor is made up of a funnel collector and a couple of calibrated collecting containers (tipping buckets). The calibrated collector area and the geometry of the collector prevents the rain from splashing in and out, according to WMO recommendations (World Meteorological Organization). Every time a bucket is filled, the instrument outputs an electrical signal that can be sent to an automatic data acquisition system. If precipitation is in a solid form, snow or hail, the instrument can measure the amount of water obtained from their melting.

Compatible data loggers

The rain gauge RG20 have to be connected to a data logger from the LOG V4 range by its M12 connector. It has a memory of 500 000 measures, communication options to define :

The loggers are multi applications and have their own configuration application templates :

  • LOG03V4 (4-20mA – DIGITAL) : Groundwater resources, CSO / SSO, Flow using pressure probe, Lift stations, Access point Hf/GPRS, …
  • LOG04V4 (Modbus RS485 – DIGITAL) : Area-Velocity Flow, CSO / SSO, Access point HF/Modbus/GPRS, Lift stations, Water quality, …
  • LNU06V4 (RS485 / Digital inputs / 4G) : Ultrasonic water level sensor, CSO / SSO, Access point HF/Modbus/GPRS, Lift station, Water quality, …
  • LNR06V4 (RS485 / Digital inputs / 4G) : Radar water level sensor, CSO / SSO, Access point HF/Modbus/GPRS, Lift station, Water quality, …

Accessories :

A configuration kit such as the Wiji USB/HF stick (Wiji USB/HF stick) allows to connect by radio to the rain gauge logger and set the configuration, and also to download on-site the data.
