Surface water
Olpas sensor for SSC (Suspended Solids Concentration) or TSS (Total Suspended Solids) monitor suspended solids and sediment in open waters in a wide range of particle sizes, independent of temperature changes or optical changes of the water.
The season‑long accuracy without the need for wipers, and easy installation make these sensors the most economic TSS- and SSC-measurement for surface waters.
The Olpas Watermonitoring sensor series provides a highly durable solution for water quality monitoring in surface water.
Equipped with advanced fouling resistance and minimal sensor drift, these sensors are designed for fixed installations or mobile platforms such as boats and buoys, and can be mounted freely or within guide tubes for stability.
“Olpas watermonitoring sensors are the most economic choice when low-maintenance is required. A once-per-3-months maintenance action was enough, while our previous sensor required a once-per-week visit. The ROI of the Olpas sensor was less than 6 months!”
Key features of watermonitoring sensors in surface waters
Maximum once-per-season maintenance (or preferably much less)
No consumables needed (no wipers or other material)
Battery or solar powered
Easy to integrate in IoT environment
Drift resistance for a continuing reliable measurement
Fouling resistance
Robust long lasting sensor
Maintenance Advantages & Cost Efficiency
Olpas Tentacle sensors are engineered for extended maintenance intervals, lasting up to four times longer than optical sensors. With exceptional fouling resistance and drift control the maintenance needs are minimal - even without automated cleaning mechanisms.
This resilience makes it the most cost-effective choice for sewer networks, WWTP influents, and other harsh environments.
Usage of Olpas Watermonitoring sensors
Sediment runoff monitoring in canals and rivers
Monitoring TSS in influent for proactive WWTP adjustments
Ensuring compliance with discharge standards
Also available: monitoring Sewers and Sewer Overflows (sewage-side or nature-side)
Sensor Hardware
Olpas sensors for water monitoring are available as part of the Olpas Tentacle hardware series, consisting of a robust sensor with power&data-cable.
A communication node can be provided to collect and store the data, and to send it to a dashboard at regular intervals.
The dual-purpose Data Cable
The cable supports both power (via solar, batteries, or grid) and data transmission, ensuring reliable connectivity for continuous operation in remote or hard-to-reach locations.
Communication & Data Access
An optional communication node collects and stores data, sending updates to a dashboard at regular intervals for easy remote monitoring. The data communication uses open standards, allowing you to integrate the measurements 100% within your own systems. There is no obligation to use our software, no expensive monthly fees are required.
