    Mounting Procedure Figure 2-2 for information on installing the meter (with a weldolet fitting) in a free- stream application. Important Always install the meter horizontally and oriented so that the gap between the tines is 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.
