Procedure
See Figure 2-2 for information on installing the meter (with a weldolet fitting) in a free-
stream application.
Important
You must always install the meter horizontally and oriented to allow flow in the gap between the
tines, irrespective of the pipeline orientation (horizontal or vertical). This position helps to prevent
the trapping of bubbles or solids on the meter – allowing the solids to sink and the bubbles to rise.

Prerequisites
• T-piece (flanged) installations are recommended for processes with the following
conditions:
