TBD-99L flow-through turbidity transmitter Introduction: The TBD-99L flow-through turbidity transmitter is primarily used in the following applications: Waterworks: turbidity monitoring of raw water before filtration, filtered water, sedimentation water, and finished water; water quality monitoring of municipal pipe networks; industrial processes: water quality monitoring of production circulating water, recycled water, effluent from activated carbon filters, and effluent from membrane filtration. Wastewater treatment plants: water quality monitoring of drainage outlets, reservoirs, wells, and clean water reservoirs. Online turbidity measurement in industries such as electricity, purified water, beverages, wine making, and pharmaceuticals. Features: 1. The turbidity sensor is equipped with built-in steady flow control and a long-path steady flow defoamer to reduce bubble interference and ensure stable water flow; 2. The sensor is equipped with automatic sewage discharge and automatic flushing devices, which are activated periodically to remove pollutants and ensure the accuracy of turbidity measurement; 3. High-brightness LED light source, long lifespan, with built-in light intensity monitoring and compensation design; 4. Standard configuration includes a white light spectrum ranging from 400 to 780nm, offering higher sensitivity with a smaller measurement range. An 860nm infrared light source is optional, suitable for water samples with color; 5. Heat the anti-fog measurement window to reduce the impact of water mist and achieve stable measurement; 6. Compact structure, easy to install, clean, and maintain; 7. Automatic range switching; 8. Equipped with extended mounting holes, allowing for the placement of more sensors; 9. It can be used for digital output, and can also be integrated with display and buttons, eliminating the need for a separate secondary meter. Technical parameters: 1. Measurement range: 0~100NTU 2.
