LDL sensors: Installation guidelines

For proper operation, some guidelines must be followed.

Orientation

Preferable mounting is just before or in a vertical pipe with flow going up to ensure a full pipe. When installed in a horizontal pipe, install the sensor at a maximum of 45° from horizontal to avoid the influence of air bubbles or deposits.

The measurement channel of the LDL200 must be installed parallel to the direction of flow. An alignment mark is laser etched on the body of the sensor indicating the correct orientation in the pipe.
