- Building a low-cost suspended-sediment monitoring stationA practical suspended-sediment station does not need a laboratory-grade cabinet, a large solar array, or a proprietary telemetry package. With a suitable…
- Understanding Nephelometric and Backscatter Turbidity SensorsTurbidity describes the loss of water clarity caused by suspended particles such as clay, silt, organic debris, algae and fine sediment. Although it is often…
- Choosing Optical Wavelengths for Turbidity Measurement in Colored WatersTurbidity measurement becomes less straightforward when water contains dissolved colour as well as suspended particles. Clay, algae, organic debris and fine…
- Optical sensor drift compensation with automatic zero and span checksOptical instruments have become central to measuring turbidity, suspended solids and sediment movement in rivers, estuaries, coastal waters and industrial…
- Deploying Suspended-Solids Sensors in Vertical Flow Constructed WetlandsVertical flow constructed wetlands are increasingly used to polish wastewater, stormwater and industrial effluent where a low-energy treatment process is…
- Turbidity Sensor Power Management Strategies For Long-Term Subsurface DeploymentsLong-term turbidity monitoring below the water surface is an energy-management problem as much as a sensing problem. A sensor may draw modest current during…
- Integrating Groundwater Profiles with Head Data for Aquifer EstimationGroundwater profilers add a vertical dimension to investigations that traditionally depend on screened bores and hydraulic-head measurements. Instead of…
- Turbidity monitoring for in-situ sediment TMDL implementationA Total Maximum Daily Load (TMDL) sets the maximum quantity of a pollutant that a waterbody can receive while still meeting its environmental objectives. For…
- Reading Suspended Solids Through Optical BackscatterOptical backscatter sensors provide a rapid way to observe particles moving through rivers, estuaries, coastal waters and industrial discharge zones. By…
- Suspended-Solids Sensor Performance In High-Viscosity Process FluidsMeasuring suspended solids in a thick process stream is more complicated than placing an optical probe in water and recording a signal. Viscosity changes how…
