When you have forward power but no reflected power, you have a matched
load. SWR with a matched load is 1:1. For other power ratios, there are
charts, slide rules and a formula to convert a power ratio to an
equivalent SWR.

SWR is one measure of the reflection coefficient. If you have a
directional wattmeter, you don`t need an SWR meter.
