Ideal for wastewater treatment plants, sewers, and industrial open channel Applications.

The SQ-R provides continuous, non-contact measurement of flow rates in effluent channels, partially filled pipes, and technical ducts used in industrial and water supply applications. Because the sensor does not come into contact with the water, it operates reliably without interference from debris or entrained solids. Its compact design and versatile mounting options make the SQ-R an ideal solution for flow measurement in manholes, facilities, and sewer systems.

Fields of Application

The SQ-R is specifically designed for municipal and industrial applications, including wastewater treatment plants, sewer networks, and process water circuits. It enables accurate monitoring of wastewater inflow to treatment facilities, supporting operational control and fair allocation of wastewater costs. In addition, the system records the duration and frequency of rain and flood events—critical data for effective sewer management by plant operators and utilities.

Implementation

Thanks to its compact design and flexible mounting options, the sensor is very easy to install—for example, under bridges or extensions, on sewer ceilings, or in manholes. The non-contact measuring technology offers a key advantage: the sensor can be mounted above the water level. As a result, the SQ-R is easy to install, readily accessible for maintenance, and not subject to clogging or blockage by entrained solids, which is a common issue with submerged sensors.

A specially designed adjustable mounting bracket is available for installation in manholes of sewers.
