Dr. Ulf Erlingsson

Dr. Erlingsson invented the SediMeter™ when he was a research student at Uppsala University, Sweden, from where he graduated as PhD in 1990, and was awarded the Linnaeus Prize from the Royal Society of Sciences in 1991. Before founding Lindorm, Inc. in 2006 he was for over a decade a senior partner in the prestigious Swedish consulting company AB Hydroconsult, established 1962, where he among other assignments served as expert for the Swedish government in supervising sediment spill monitoring during the building of the Öresund Bridge to Denmark. After founding Lindorm and designing the first modern SediMeter, SM2, he installed the first real-time SediMeter monitoring system in Honduras as part of a consulting assignment for IAEA in 2009, which also included an assignment as bathymetry expert. Since then he has continued refining the hardware and software to the state of the art system of 2020. Erlingsson is a member of the Coastal Education & Research Foundation.

While his career has been focused on sediments and ways to study them using modern technology, he has also dedicated himself to science and philanthropy, as described in his biography. Please use the Contact form to request a free consultation or to inquire about our products.
