Sensor for TSS

The cutting-edge MES5 probe for total suspended solids and turbidity measurement in water, is engineered with advanced optical infrared absorptiometry technology, ensuring accuracy and reliability in numerous water treatment applications.

Why measure TSS and Turbidity in water?

Monitoring total suspended solids (TSS) and turbidity is paramount for safeguarding water quality. Neglecting these crucial parameters can lead to severe consequences, jeopardizing ecosystems, and human health. Elevated TSS levels diminish water clarity and disrupt aquatic habitats while turbidity measurements reflect water cloudiness, a key indicator of contamination. Failure to monitor TSS and turbidity could compromise the effectiveness of wastewater treatment, impact industrial processes, and result in environmental degradation. This emphasizes the critical role of Aqualabo’s MES5 probe in averting such consequences through precise measurement and informed water management.

Main applications of TSS and turbidity measurement with the MES5 probe

In urban wastewater treatment, it monitors TSS and turbidity levels in inlet or sewage networks, it ensures optimal conditions in aeration basins and monitors turbidity at the outlet. Industrial effluent treatments also benefit from accurate TSS measurements in aeration tanks, while sludge blanket detection aids in clarifiers, whether it is for urban or industrial waters. Our MES5 sensor additionally plays a vital role in sludge treatment ensuring efficiency and correct processing. Furthermore, MES5’s role extends to dredging sites, providing essential environmental data.

Measurement principles used by Aqualabo MES5 sensor for TSS and turbidity

Aqualabo’s MES5 probe uses optical transmittance measurement in the infrared spectrum, operating at 870 nm, it measures the signal attenuation over a 5mm optical path. With temperature-controlled optics, the probe guarantees accuracy even with process variations. The sensor is to be calibrated with specific samples to provide an accurate TSS concentration measurement in g/l. Up to 10 different calibrations can be stored in the sensor, allowing a specific coefficient to be recalled for each specific process stage to be monitored. Finally, formazine is used to calibrate turbidity measurements that are expressed in FAU.

Why use and trust Aqualabo’s MES5 probe

This sensor is ideal for harsh environments such as wastewater. The rugged construction ensures durability and stability of measurement over time. The efficiency of the measurement and its simplicity give you an excellent tool to implement the measurement of TSS and turbidity at the same time. The MES5 features a wide measuring range, covering TSS from 0-50 g/L and turbidity from 0-4000 FAU. The pre-amplified signal and Modbus communication ensure seamless integration into your process control, without signal or measurement interference.


FAQ Sensor MES5

You can calibrate the light transmittance signal in two points: a 0% is calibrated by signal extinction and a 100% with distilled water. Between these two points the response signal is linear. Turbidity FAU readings are calibrated with a formazine solution and TSS by using a sludge or wastewater sample. You can insert the real concentration from the sample later, once known. Up to 10 separate sample specific coefficients are stored in the sensor.

Yes, absolutely! On the one hand, its ability to store multiple specific calibration coefficients makes it the best option for manually monitoring several process stages in a wastewater treatment plant. On the other hand, its rugged construction and universal Modbus communication make it perfect for online monitoring and easy integration into a process control system.
