Page 6: Introduction And How To Use
Introduction and How to use QWT-CL900 Leakage Automatic analyser is a superior performance of the full- automatic leaking Detector,which overcomes the single leak detector is easy to exist he problem of miscarriage of justice due to the pipeline of liquid, gas flow rate or pressure Change.The Specific pipeline leak detection method includes: arranging a group of samplers in a linear or matrix manner in the leak detection area of the pipeline. - Page 7 Figure 2 Boot Page Figure 3 Home Page Double-click the “Automatic Analysis” (Figure 4) Figure 4 Automatic Analysis Page Click the “Probe Info” in the upper right corner of the Automatic Analysis page to ensure that each Probe is online and click “CAL” . After observing the data of each probe on the screen, click "Save".
- Page 8 Figure 5 Probe Info detection page When “CAL” is complete, click “Return” to the Automatic Analysis screen. Click the “Filter Settings” and select the desired measurement frequency range (Note: the “HP” frequency is selected as the lower frequency limit and the “LP” is the upper frequency limit, so the “LP” select Frequency higher than the “HP”, or will not appear signal ).

Page 9: Pipeline Leak Testing
Figure 8 Signal Column is too high Pipeline Leak Testing Place all probes in the area to be probed,The signal column is not significantly higher than the anomaly, indicating leakage point is not within the detection (Figure 9) Figure 9 Then, place each wireless probe in other areas of the detection area, continue to repeat the above steps and observed until the signal column was significantly higher than the abnormal (Figure 10). - Page 10 When lock the leaking around to verified the real leaking, Use the host machine connect to the sensor for “Spectrum Analysis” & “Filtering Analysis” ( 1) Plug five core cable into the host sensor interface and screw locking ( 2 ) Plug four-core cable into the interface of sensor and mounting screws ; ( 3 ) Headphone into the headphone jack and make sure the connection is correct .
- Page 11 "A. 24 Fixed Frequency ", you can see the 24 selection buttons, click to select one which indicates the center frequency of the band-pass filter. Scrollbar on-screen indicates the instantaneous intensity of the center frequency of the noise signal , and the right side of the scroll bar represents the corresponding value of the noise signal.( Regular choose the frequency at 200-1000Hz) ...
- Page 12 3. Suspected Leakage Point ( The high spectrum indicate the leaking point) Long-Term Mode Long-Term Mode refers to conduct further analysis to determine the suspicious leakage points detected in preliminary investigation. It is in order to exclude suspected leak but is actually three direct links, noise impact sound of water at the valve or other underground facilities issued in order to find the true leakage points and design.
- Page 13 Figure 2 Whether to raise or lower the sensitivity, the curve volatility is big, can judge where leaks . (See Figure 3, Figure 4 ) Figure 3 Figure 4 Intermittent increase and decrease in water pipes and a larger amplitude: whether to raise or ...
- Page 14 Whether to raise or lower the sensitivity, the recess amplitude of increase and decrease is big, can judge where is the leakage point. ( See Figure 7, Figure 8） Figure 7 Figure 8 Pipeline Flow is Larger Whether the sensitivity is raised or lowered, curve magnitude has been higher in value, can’t judge the leakage point, should find another time monitoring.
- Page 15 Figure 10 Figure 11 In the same suspected leakage point, curve amplitude is higher in peak water while the curve amplitude reduce at the low water peak. ( See Figure 12, Figure 13） Figure 12 Figure 13 Proving in water peak, the monitored noise is the sound of water or other external causes, it can...
