SoliTechw² IL Suspended Solids and Sludge Density Sensor

Inline Sensor for sludge density, suspended solids and turbidity monitoring

The SoliTechw² IL sensor provides reliable and repeatable, continuous in-line measurement of sludge density, suspended solids and turbidity.  The optical element has a sapphire window, this offers excellent resistance to fouling and damage caused by the abrasion from flow particles.

The sensor is suitable for a variety of applications including the auto de-sludging of primary and final settlement tanks, and reliable sludge density measurement ensures that downstream treatment processes can operate at their optimum level.

The sensor is installed through a mounting boss onto any pipeline that is larger than 65 mm diameter. The sensing element is positioned flush with the inside wall of the pipe, ensuring that the optical surface is kept clean by the flow passing the sensor and making sure the sensor does not cause an obstruction to the flow.
