Quadbeam Technologies’ storm and wastewater sensor, the SWW, is a unique suspended solids sensor/turbidity meter. The intended use of the S20-SWW and S40-SWW sensors is the continuous monitoring of suspended solids concentration in non-hygienic industrial and wastewater installations.
Quadbeam uses the four-beam alternating light ratiometric system of measurement for its sensors. Suspended solids sensors and turbidity sensors measure the change in light intensity to produce a relative measure of the solids or turbidity concentration in the liquid being monitored. Some other suspended solids sensors and turbidity meters use only a single beam of light. When a single beam of light is used light intensity can be influenced by not only the solids particles suspended in the liquid, but also any solids/contamination that are stuck to the surface of the sensor and variability of the light source and photo diode as they age. It is therefore critical to keep single beam sensors very clean for accurate readings.
Multi-beam sensors measure across multiple light paths allowing them to use mathematical algorithms where the change in ratio of intensity of light is measured. This system automatically compensates for contamination stuck to the surface of the sensor and variation of the light components in the sensor. For this reason, it is common for multi-beam sensors to be used in process control installations, where a repeatable output is important.
The sensors can be used in a wide range of turbidity and suspended solids monitoring and control applications, including: stormwater sediment monitoring and control, wastewater suspended solids monitoring, flocculant dosing control, environment turbidity monitoring, raw water supply, remote turbidity monitoring, and irrigation water turbidity monitoring.
