Transducer Positions
This section of the Pipe tab is for setting the transmitter information.
Use each drop-down menu to select the appropriate transmitter color, from
left to right, in the pipe network. A grey selection indicates no transmitter.
Consider using the yellow option when using the Receiver Unit as an input
with a plug-in transducer. Once selections are completed, click on the
Apply button to set the changes.
Yellow Transducer
When using three transducers, enter the distance from the middle
transducer to the left transducer. Adding a 3
rd
transducer changes the
correlation display so that tabs at the top allow selections between the
different combinations of transducers.
Hydrophones
Select this checkbox when using hydrophones.
Calculate
Use Calculate to determine the velocity of sound in the pipe in either 2-
Transducer mode or 3-Transducer mode.
Velocity Calculation (2-Transducer Mode)
This allows measurement of the actual velocity of sounds in the pipe(s).
However, a leak in the pipe must exist at a known position, typically
produced by opening a hydrant. Two primary options are available for the
leak position: Out-of-Bracket or Between Sensors.
