Sequoia’s LISST-Infinite and LISST-Hydro products generate data on sediment concentrations in water entering turbines. However, there has been no guidance for plan operators on what levels are dangerous, or at what level the operator should shut down turbines. At a conference of the IAHR in Grenoble,...
While testing a LISST-ABS in the laboratory with field samples, Dr. Benjamin van der Waal of Rhodes University in South Africa noticed an apparent instrument drift. He was using samples extracted from a river for this testing, so that the samples were likely a mixture of cohesive sediments. In a test...
The optical scattering function (VSF) describes how incident light on a volume of water is scattered into various directions. It is an important inherent optical property of water – a term used by optical oceanographers. The VSF at small forward angles is important in determining beam spread or in...
Upon first impressions the LISST-200X appears to be just a smaller version of the LISST-100X. However much of what makes the LISST-200X such an improvement over the LISST-100X is what lies deep inside the instrument. Let’s explore these features in more detail to see why the LISST-200X is truly Smarter. Comparison...
Truly Portable Instrument Reduces Drilling Costs UPDATED 15 AUGUST 2017 The size distribution of drilling muds is frequently adjusted during the drilling process. As such, the particle size distribution must be measured frequently, several times a day. Before the introduction of our LISST-Portable|XR,...
Last updated: 11 May 2016 Turbidity as a surrogate for suspended sediment concentration (SSC) is commonly used and deeply established in practice. The shortcomings of turbidity as a surrogate for SSC are: The calibration changes with grain size; The calibration changes with sediment color; and Turbidity...
LISST-Infinite installed next to a draft tube. Sequoia’s LISST-Infinite instrument is made to protect turbines by sounding alarms so that plant operators may decide to shut down power production and save turbines from abrasive damage. The instrument system consists of a mechanism to deliver...
Click here for a link to PiE 2016 Daniel M. Hanes, Colin Jago, Ole Mikkelsen, and Yogesh C. Agrawal With the recent announcement that a fifth “Particles in Europe” (PiE) conference will be held in Budapest in Fall, 2016, it would be useful to the community of potential participants to review the...
[Readers should be aware that due to the different nature of size dependence of optical and acoustic backscatter sensors, changes in grain size distribution can cause the two data to not track. Neither sensor holds calibration with changing grain size. The LISST-ABS does hold calibration for grains...
