The stored water leakage detection data can be transmitted to the computer quickly and concisely.
Large LCD
LCD screen display (128 × 64), this device will allow you to easily see the water leakage detection results and is easy to operate. With the help of background lights, data can be read clearly both day and night.

Technical advantages of Fuji DNR-18 digital screen noise and leakage detector in Japan:
Sensitivity probe with digital amplification
Sensitivity piezoelectric sensors, which are probes that pick up water leakage sounds. As is well known, Japan ranks among the top in the world in the manufacturing technology of piezoelectric ceramics. Fuji has made good use of this environment and has put in a lot of effort in the core technology of leak detector sensors for many years. The comprehensive sensitivity of DNR-18 sensors has reached over 900V/G, which is more than 1000 times higher than the original products.

Digital integrated screen technology
Dynamic noise reduction technology (DNR), currently used as the digital screen noise reduction technology in Fuji leak detectors in Japan. This technology can effectively remove any discontinuous sound in any range, and its application greatly reduces the environmental requirements for listening to leaks, allowing operators to hear clear leakage sounds even in poor environments and accurately locate the leakage point.
Segmented/Bandpass Filtering (BPF) technology, the instrument filters the sound signal picked up by the probe to control the signal within the frequency range of 0-2200Hz, which reflects the sound of water leakage. At the same time, it can be combined into 19 different widths and frequency ranges from low to high according to the needs of the site.

Hierarchical filtering technique (NF), which can effectively filter out continuous interference noise of a single frequency. For example, the electric current produced by alternating current, vending machines, transformers, etc.
Digital audio recording and analysis technology
Can analyze and capture the * small sound pressure value of any listening point and record the relevant data;

It can store the * small sound pressure value data of 250 listening points at once, and these 250 data can be arbitrarily grouped and clearly marked, without confusing the data of different sites in a work record;

The instrument automatically analyzes the data and displays any set of sound pressure change curves or bar charts on the screen according to the needs of the listener;

All data can be easily transferred to a PC for further processing and archiving through Chinese software.

The application of these technologies can eliminate the impact of changes in water usage in pipelines on leakage sounds, helping operators analyze the distribution of leakage sounds on pipelines and accurately determine the leakage point.
