Product Description

The scattered light meters are delivered with the sender and receiver units gathered in one unit. Light is sent into the process by a well-defined angle in relation to the flow direction. The sender/receiver unit is also installed in a well-defined angle in relation to the flow direction.

The light that the dust particles in the process reflect back onto the receiver unit is an expression of the dust concentration in the process. Optical dust measurement is a relative and not an absolute measurement because the dust particles do not have a well-defined density and because the reflecting/absorbing qualities will vary depending on the application.
