Expert in Water Quality Measurement and Water Treatment Project Since 2007
Product Overview
- BOQU Online TSS (MLSS) Meter system measures total suspended solids/suspended solids continuously. It consists of an IP68 submerged TSS sensor (SUS316L or titanium alloy options) and an IP65 transmitter/display (TSG-2087S). The sensor supports multiple measurement ranges (0.01–20,000 / 45,000 / 120,000 mg/L) and communicates via RS485 Modbus RTU to the transmitter or other control systems.
Product Features
- Wide measurement ranges up to 120,000 mg/L with resolution and typical accuracy ≤ ±5% (dependant on sample homogeneity) and transmitter accuracy ±2%.
- Standard digital and analog interfaces: RS485 Modbus RTU, 4–20 mA output and three configurable relays (high/low alarms and cleaning control).
- Auto-clean brush function and one-click cleaning relay to reduce fouling and maintenance.
- Durable construction: sensor main body in SUS316L (standard) or titanium (seawater), PVC covers and cable; IP68 sensor housing and IP65 transmitter.
- Built-in datalogger and USB interface for easy data download; sample and slope calibration supported; standard 10 m cable (up to 100 m).
- Operating conditions: sensor pressure ≤0.4 MPa, flow velocity ≤2.5 m/s, ambient temp 0–45°C; 1-year warranty.
Product Value
- Reliable real-time monitoring of suspended solids/MLSS allows optimized process control (aeration, sludge return, clarifier operation), reducing chemical and energy costs.
- Reduced downtime and lower O&M expense due to auto-cleaning and durable materials; longer sensor service life in harsh environments (including seawater option).
- Easy integration into SCADA/DCS via Modbus and 4–20 mA for automated control and regulatory compliance reporting.
- Local data logging and USB export simplify diagnostics, trend analysis and audit trails.
Product Advantages
- Extremely broad measurement capability (up to 120,000 mg/L) suitable for concentrated sludges where many sensors fail.
- Robust materials and IP68 rating for submerged, harsh wastewater applications; optional titanium for corrosive/seawater environments.
- Multi-output flexibility (analog, digital, relays) and integrated datalogging support diverse control and monitoring architectures.
- Auto-clean brush reduces manual cleaning frequency and operational costs.
- Compact sensor design and long cable options (up to 100 m) ease installation and retrofit into existing plants; backed by experienced manufacturer support.
Application Scenarios
- Municipal and industrial wastewater treatment: primary and secondary clarifiers, mixed liquor monitoring, aeration basins, return activated sludge (RAS) control, final effluent monitoring.
- Inlet/effluent on-line monitoring for regulatory compliance and process optimization.
- Industry-specific uses: pulp & paper, dairy, mining, chemical processing and other industries handling high solids streams.
- Any application requiring continuous MLSS/TSS measurement for process control, alarm/trip logic or data logging and remote integration.
