Selecting and mounting guide pipes

Guide pipes are required for most installations, except for tank top and underground

applications. Guide pipes are usually used in three locations:

• Gauge head to sheave elbow

• Sheave elbow to sheave elbow

• Sheave elbow to tank roof

Precautions regarding installation

• Note that guide pipes and pipe supporters are not supplied by Endress+Hauser.

• Ensure that any bends in guide pipes are 5 mm (0.17 in) or smaller.

• The space (piping distance) between a sheave elbow and a sheave elbow must be no

more than 2.5 m (8.2 ft).
