Of course. With one side of the Bird wattmeter

the reflection coefficient of the line connection

Any way you choose to look at the example, the same
amount of joules are flowing into the source as are
flowing out of the source during any particular time
period. That is a power reflection coefficient of 1.0
Take the square root to find the voltage reflection
coefficient of plus or minus 1.0
