Water Monitoring
Olpas provides sensor for monitoring water quality for trends or to follow up on events. The extensive (bio)fouling resistance makes our technology the best choice for use in sewer overflows (CSO), sewer networks and remote open waters .
The Olpas Tentacle sensor series includes a sensor connected to a cable for power supply and data transmission. These sensors are suitable for fixed installations or for use on movable platforms like boats or buoys. It can be positioned either hanging freely or enclosed in a guide tube to restrict its movement.
The data cable serves the dual purpose of supplying power (from solar, batteries, or the grid) and enabling data connectivity.
A communication node can be provided to collect and store the data, and to send it to a dashboard at regular intervals.
Reduced drifting and significantly extended maintenance periods
Thanks to the remarkable fouling resistance of the OLPAS Technology and Olpas sensors, the Olpas Tentacle stands out as the most cost-effective option for use in sewer systems or sewer overflows. Even in the absence of wipers or other automated mechanical cleaning mechanisms, Olpas sensors offer maintenance intervals that are four times longer than those of optical sensors (which require wipers and mechanical cleaning).
Due to the OLPAS technology's resilience to (bio)fouling in demanding settings like sludge dewatering, iron water, filtrate, sewers, and WWTP-influent, the Olpas Tentacle sensors offer dependable measurements over several weeks or months with minimal or no maintenance required, thanks to their long maintenance intervals design.
"Olpas has the only measurement technology that is optimised for reliable multiple-saison monitoring campaigns in sewers or Combined Sewer Overflows (CSO) with only minimal maintenance."
The Olpas Tentacle sensor range has been developed with these specifications in mind:
Hard to reach locations (sewers or remote locations)
Harsh environments that require frequent cleaning
No tolerance for drift
Monitoring sewers & sewer overflows
Due to their difficult accessibility and cleaning requirements, sensors in certain locations pose challenges for regular maintenance, often resulting in high costs. Fortunately, Olpas sensors offer exceptional fouling resistance, significantly reducing the need for frequent maintenance.
This makes the Olpas Tentacle sensors very suitable for measurements in sewers, combined sewer overflows (CSO) and influent of WWTPs.
Monitoring sediment runoffs in canals and natural rivers
By monitoring sediment loads in open waters or canals, valuable insights can be gained. The Olpas sensors' fouling resistance reduces the need for frequent maintenance (usually once per season is sufficient) and ensures accurate measurements unaffected by drift.
Other applications:
Monitoring TSS in influent, in order to pro-actively adapt the WWTP
Protection against breakthrough of filters
Ensuring compliance with discharge standards
