Note: Velocity units are available: m/s (metres per second) and f/s (feet per second)

 

In order to display the current velocity in the system being measured it will be necessary to select the 

following:

 

1 .

 

The valve being measured (Main Menu >> Select Valve) 

2 .

 

The pipe size (Main Menu >> Pipe Size)
