OTT Hydromet’s new self-draining rain sensor

The OTT WAD Rain Sensor

OTT WAD Rain SensorOnline —  The OTT Hydromet Group is one of the leading providers of hydrological and meteorological sensors. These include various measuring systems for the detection of liquid and solid precipitation.

The sensors can be used in both cold and warm climate zones.

Recently, the precipitation sensor family has been joined by two new models: The maintenance-free, radar-based Lufft WS100 in 2017 and the OTT WAD Rain Sensor in 2018.

WAD stands for “weighing and draining” and describes a unique measuring principle that combines the advantages of weighing and collecting rain gauges.

The high measuring accuracy meets the requirements of WMO guideline No. 8. It specifies that rain sensors have a maximum inaccuracy of ± 3%.

In addition, it outputs precipitation intensities and total values in real time in the impressive measuring range of 0.001 to 720 mm/h.

The new, self-draining tilt-balance system represents an alternative to the OTT Pluvio² sensor and is especially suitable for use in subtropical and tropical climates. (more…)
