Water Monitoring

Water Monitoring

Olpas provides reliable water quality monitoring with advanced industry leading (bio)fouling resistance and minimal sensor drift, making these sensors the ideal choice for sewer overflows (CSO), sewer networks, and remote open waters.

The Olpas Water Monitoring sensor series provides a highly durable solution for water quality monitoring in challenging environments like sewers, combined sewer overflows (CSOs), and open waters.


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.

Choose Olpas Water monitoring sensors for a reliable, economic, low-maintenance water quality monitoring in demanding environments, across multiple seasons.

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, Olpas Tentacle minimizes maintenance needs - even without automated cleaning mechanisms.

This resilience makes it the most cost-effective choice for sewer networks, WWTP influents, and other harsh environments.

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.



Usage

Sewer & Sewer Overflow (CSO) Monitoring

Olpas Water monitoring sensors are ideal for hard-to-access sewer systems and combined sewer overflows (CSO), where maintenance can be costly and frequent. The exceptional fouling resistance reduces maintenance demands, providing reliable, season-long monitoring.

Sediment Runoff Monitoring in Canals and Rivers

With resistance to fouling and drift, Olpas sensors deliver accurate, low-maintenance sediment load measurements in open waters and canals, often requiring servicing only once per season.
