PQWT-CL300 automatic pipeline leak detector is used to find and determine the location of the leaking point of the water supply pipeline. It can also be used for leak detection of other pressure pipeline systems. When the fluid in the pipeline escapes under pressure, it generates noise energy. Propagation along the pipeline or along the buried medium to the ground.
1, the use of foreign digital signal processing chip and digital filter chip, the controller integrated 16M cache, the reaction is more sensitive. In particular, it is able to filter environmental noise disturbances, identify leaking noise, and allow operators to more quickly lock water leaks.
2, using 7-inch high-definition digital touch color LCD screen resolution of 800 * 480, can provide 12 display paging, can be more clearly and intuitively display the measured parameters, and full touch screen design, simple operation.
3, with a frequency range of 1 ~ 6000Hz (spectrum analysis), can show the distribution of noise signals at various frequencies in real time.
4. Automatically draw a continuous noise curve (point measurement) within a certain period of time, so that the determination of the leakage point position is faster.
5, the sensor built-in preamplifier circuit, the use of rubber ring seal and buffer, and the application of professional acoustic methods, making the ability to capture noise is higher than similar products.
6, using a new noise detection component, clear sound quality.
7, can maintain long-term recording, the number of recording segments is not limited, shutdown is not lost, ready to analyze.
8, the use of large-capacity battery, can work for about ten hours, and can remove the charge and on-line charging, convenient and quick.
9, anti-interference circuit design, the digital signal and analog signal were effectively isolated, eliminating the noise generated by the digital circuit.
