Model SBS Range - Precipitation Sensors



SBS Range of Precipitation Sensor. With the SBS Range of precipitation sensors (rain gauges) EML took the proven aerodynamic shape of the ARG100 and developed it to the next level. This sensor is manufactured from specially formed aluminium material which allowed for fine tuning of the aerodynamic shape to further reduce the wind effect.

The SBS gauge can be purchased with three different sizes of funnel, adding flexibility for our users' application.  The smallest funnel size (SBS314) is a hugely popular export to our large consumer base in Eastern Asia where rainfall intensities are very high and a smaller orifice is beneficial.  The SBS500 and SBS1000 are popular in more temperate climates where a greater funnel-size provides superior areal coverage for low to medium rainfall intensities.

The SBS is the result of over 3 years extensive fieldwork carried out by the renowned Dr. Ian Strangeways to determine the most effective design of precipitation sensor for accurate rainfall measurement in all climatic conditions, irrespective of wind speed and type of precipitation e.g. drizzle or heavy, convective or tropical rain. The unique design and aerodynamic shape of the SBS rain gauge increases measurement accuracy by capturing more rainfall than traditionally shaped cylindrical gauges, minimising out-splash and reducing rainfall losses caused by evaporation.

The funnel of the gauge is made from 2.5mm thick powder coated aluminium while the base is manufactured in LM6 marine grade aluminium. The gauge can therefore be installed in extremely hostile conditions. A version with internal heaters is also available for cold climate installations.  If you value accuracy and require longevity and durability, the SBS is the precipitation sensor for you - just ask the Scottish Environmental Protection Agency (SEPA) who have installed 300 SBSs in their sensor networks!
