SS-99 Online Suspended Solids Concentration Meter

Product Introduction
The SS-99 Online Suspended Solids Concentration Meter is designed for continuous monitoring of suspended solids (SS) in municipal sewage and industrial wastewater treatment processes. The system consists of a transmitter and a sensor, supporting installation in tanks, drainage pipes, pressurized pipelines, and natural water bodies.
With optical measurement, automatic sensor cleaning, and water-color compensation, the SS-99 helps reduce routine maintenance and provides stable suspended solids measurements for wastewater process monitoring. Multiple sensor configurations are available to accommodate different concentration ranges and operating conditions.

Performance Features
• Wide Measurement Range: Sensor options cover suspended solids concentrations from 0–1,000 mg/L to 0–50 g/L.
• Optical Scattering Measurement: Uses a modulated single-beam light source and scattered-light detection to measure turbidity and suspended solids.
• Automatic Sensor Cleaning: An automatic cleaning wiper and timed air-cleaning function help reduce manual maintenance.
• Water-Color Compensation: Compensates for sample color to minimize its influence on measurement results.
•Automatic Range Adaptation: Measurement modes switch automatically to accommodate a wide concentration range.
•Digital Sensor Processing: Integrated signal processing improves measurement stability and reliability.
• Ambient Light Interference Reduction: Optical bandpass filtering and modulated excitation light reduce external light interference.
• Historical Trend Display: Large LCD with Chinese-language menus displays measurement data and historical trends.
• Flexible Communication: Optional Modbus RTU/RS485 communication and 4–20 mA analog output.
• Alarm Outputs: Supports two alarm relay outputs.

Working Principle
The SS-99 uses an optical scattering method with a modulated single-beam light source. When light interacts with suspended particles in the sample, the scattered light is detected by the sensor and converted into an electrical signal. The signal is processed to determine suspended solids concentration.
Optical filtering and modulated excitation help reduce ambient light interference, while color compensation minimizes the influence of water color. Digital signal processing and automatic cleaning help maintain reliable operation during continuous wastewater monitoring.
