   en.wikipedia.org/wiki/Rosemount_Inc.

   Rosemount Inc. is a subsidiary of Emerson Electric Company.Its headquarters is located in Shakopee, Minnesota, where they manufacture measurement instrumentation such as pressure, temperature, level, DP flow, and wireless, as well as analytical and detection instrumentation for gas analysis, liquid analysis, combustion measurement and flame and gas detection.

3. Turbidimetry - Wikipedia

   en.wikipedia.org/wiki/Turbidimetry

   Turbidimetry (the name being derived from turbidity) is the process of measuring the loss of intensity of transmitted light due to the scattering effect of particles suspended in it. Light is passed through a filter creating a light of known wavelength which is then passed through a cuvette containing a solution.

4. ISO 7027 - Wikipedia

   en.wikipedia.org/wiki/ISO_7027

   ISO 7027:1999 is an ISO standard for water quality that enables the determination of turbidity. [1] The ISO 7027 technique is used to determine the concentration of suspended particles in a sample of water by measuring the incident light scattered at right angles from the sample.

5. Total suspended solids - Wikipedia

   en.wikipedia.org/wiki/Total_suspended_solids

   Although turbidity purports to measure approximately the same water quality property as TSS, the latter is preferred when available as it provides an actual weight of the particulate material present in the sample. In water quality monitoring situations, a series of more labor-intensive TSS measurements will be paired with relatively quick and ...

6. Turbidity - Wikipedia

   en.wikipedia.org/wiki/Turbidity

   Turbidity is the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye, similar to smoke in air. The measurement of turbidity is a key test of both water clarity and water quality. Fluids can contain suspended solid matter consisting of particles of many different sizes.

7. Secchi disk - Wikipedia

   en.wikipedia.org/wiki/Secchi_disk

   Different kinds of Secchi disks. A marine style on the left and the freshwater version on the right. The Secchi depth is reached when the reflectance equals the intensity of light backscattered from the water. 1.7 divided into this depth in metres yields an attenuation coefficient (also called an extinction coefficient), for the available light averaged over the Secchi disk depth.
