Sound velocity measurement
89
12.2.2 Procedure
To calculate the sound velocity in the pipe, proceed as follows:
Step Description
1
In the Correlator's Start menu, use the two arrow buttons to choose the required
Offline measuring mode (e.g. “COR MS-3 with microphone”).
2
In the main menu, tap the button
.
3
In the displayed menu, tap the
Tools
button.
4
In the displayed menu, tap the
Velocity measurement
button.
Result:
The following menu opens:
The square boxes represent the Multi sensors (1 to 8) or Power transmitters
(A and B) used in the measurement.
The scheme below illustrates how the sensors must be positioned in relation to
the source of noise. Take care to follow this scheme when selecting the three
sensors for the measurement. Otherwise the result of the calculation may be
wrong.
5
Select the sensor which represents Position 1 (sensor “in front of” the sound
source) by tapping the required box.
Result:
The number of the selected sensor is shown at position 1. The white
highlighting switches to position 2.
6
Select the sensor which represents Position 2 (first sensor “behind” the sound
source).
7
Select the sensor which represents Position 3 (second sensor “behind” the sound
source).
8
Tap the
OK
button.
Result:
The menu for calculating the speed of sound opens.
