Digital Filter Water Leakage Detector
Product Features of bd Digital Filter Water Leakage Detector
> Adopts a dot-matrix liquid crystal display that can be backlit to meet the needs of horizontal length and vertical light beams. And can be easily observed at night.
> The three-level bandwidth change not only takes care of the richness of vibration energy distribution during the listening process, but also allows for more detailed frequency analysis.
> Ad hoc storage of each channel can store not only the frequency band signals but also the measured values of each measuring point.
> The designed special engineering plastic chassis and corresponding panel operation are very simple and clear. Clear and extensive information can be obtained with a convenient and simple operation method, making the actual leak detection work convenient and easy.
The digital filter leak detector is a special instrument used to find and determine the location of leaks in water supply pipelines. It can also be used to detect leaks in other pressure pipeline systems. When the fluid in the pipeline escapes under pressure, noise energy is generated. Spread along pipelines or along buried media to the ground. The leak location can be determined along the pipeline or above its road surface.
bd digital filter water leak detector
It is a leak detection instrument that uses a low-power microprocessor and an advanced special filter to digitally process noise. It uses a specially designed broadband high-sensitivity vibration sensor (vibration pickup Detector), the noise on the ground (or pipe mouth) is picked up and converted into an electrical signal. After corresponding amplification and digital filtering, it is displayed on the LCD screen in two display modes. It is noted that the water leakage noise is a continuous signal. In the digital processing, the frequency band rotation detection method of continuous noise is used to generate a display histogram, while the sudden impact interference is suppressed (not displayed). It is also noted that the possible superposition of external interference is adopted, and the minimum value method is used within the corresponding time of the value, and the corresponding numerical display is given to suppress external interference to the maximum extent.
