Geolux Instruments

Founded in 2007 in Europe, Geolux manufactures radar instruments for water level and surface velocity monitoring. These instruments transmit radio waves towards the water surface and, as the transmitted waves bounce back from the water to the instrument, measure water level, and surface velocity. The use of radar technology allows the instruments to be mounted up to 30 meters above the water surface, making installation quick and simple, while keeping maintenance minimal.


Geolux RSS-2-300 W is a surface velocity radar that measures surface velocity in open channels. It can be combined with the water level sensor to calculate the total discharge based on water level and surface velocity measurements. The accuracy of this instrument has been certified in the Swiss METAS institute. Geolux products are being used in over 5000 locations in Africa, North and South America, Asia, Australia, and Europe.

Van Essen Instruments

Van Essen Instruments was founded in 1938 by Cornelis van Essen in Delft, Netherlands. In the early 1990s, Van Essen began to offer standard water related equipment such as standalone dataloggers, which used external sensors and flow meters for open channels. Van Essen was one of the first companies to develop a tide measuring system for the Rotterdam Harbor. In this project telemetry was used. Telemetry was very advanced for its time and became a key milestone in Van Essen’s growth.

Since the deployment of the first Diver, Van Essen Instruments have sold over 200,000 dataloggers worldwide for groundwater monitoring. Commitment to quality and performance has established Van Essen Instruments as one of the premier brands in the industry.
