Yangtze River Sediment Data

LISST-SL2 Is Demonstrated in Yangtze River, Wuhan, China The Yangtze River hydrological facility is located in Wuhan on the western bank. A map of the location can be found here (30°37’41.59″ N 114°19’37.23″ E). With help from personnel at the local station, a research vessel...

Data Products of LISST-SL2

Real Time Displays, and Immediate Averaged Results The new LISST-SL2 river sediment monitoring instrument is a greatly simplified and powerful device. The instrument transmits data immediately upon being lowered into water. Data can be viewed in real time, or after processing for averages. Click here...

Working Limits of Particle Concentrations

The following is a simple description for non-specialists. For an advanced description, please click here. As with any instrument, the LISST-100X or LISST-200X instruments have limits on their working range of particle concentration. In this article, we explain the basis of these limits. The figure below...

Rich Details of a River Column Revealed by LISST-SL

UPDATED 18 SEPT 2017   The LISST-SL2 instrument delivers the most powerful suite of sediment data. It is an isokinetic instrument (isokinetic means intake velocity matches river velocity). The parameters it measures are: depth, optical transmission across 3mm path, river velocity, water temperature,...

LISST-ABS River Profiles by USGS

UPDATED 09 SEPTEMBER 2017 As described in related articles, the LISST-ABS has a near-constant sensitivity (Volts/concentration) for sediment particles in the >30 micron size range [see Features section here]. In contrast, the sensitivity of optical turbidity degrades with increasing grain size. This...

Measuring Particle Size Distribution of Cement

Laser Diffraction Analysis of NIST 114q Cement per AASHTO Standard T353-14   Laser diffraction analysis of cements is a common industry practice to control quality of cements. Typically, companies must invest in multiple instruments at as many stations. The LISST-Portable|XR is truly portable –...
