4.4.2 W Method
In many instances, flowmeter performance on small metallic pipes with outer diameters of 4 inches
(100 millimeters) or less can be improved by using the W mounting method (Figure 4.4-B, below). With the
W method, the sound wave traverses the fluid 4 times and bounces off the pipe walls 3 times. Like the
V method, both transducers are mounted on the same side of the pipe.
Ensure W is the selected mounting method.
