Installation:

 

1. The wetted parts need to immersed in fluid.Installation in small diameter pipeline to ensure that the probe can’t contact with pipe’s inner wall.

2 .When the fluid can not completely fill the pipeline, products should be installed in the bottom of the pipe. (Figure 1)

3. If there may be sediment in the pipeline, please products installed in the pipeline side wall, horizontal mounting (Figure 2), to avoid the air and sediment

4. Installation in a straight pipe close to bend or intersection place, the pipe length should not be less than 4 times the diameter of pipeline.
