8-6-2-3 Estimation of Gas Leak
Turn on the function of leak cost estimator in the equipment. The acoustic device
automatically enables the focusing function by default to avoid interference. At
the same time, it fixes the test frequency band to the 25kHz-40kHz to ensure
leak calculation accuracy
.
There are options of air pressure and distance on the left side of the software.
The user needs to input the air pressure (unit: kPa) and distance (unit: cm) of
the leaking gas according to the parameters of the site. The built-in calculator
calculates the leakage level and the approximate range of gas leakage according
to the gas pressure, distance, and calculated leakage energy (for reference).
The gas leakage levels are divided into 7 classes and the corresponding leakage
ranges are shown below:
Leakage Level
Leakage Range (Unit: ml / min, for reference)
0
<10ml/min
1
>10ml/min to <200ml/min
2
>200ml/min to <500ml/min
3
>500ml/min to <1000ml/min
4
>1000ml/min to <1500ml/min
5
>1500ml/min to <2000ml/min
6
>2000ml/min
