Underground Pipeline Water Leak Noise
Digital Detector Features
The underground sound wave is first converted into an electronic signal by a water proof accelerometer. Measurements of the signal intensity are then made at regular intervals (sampling). At each sampling point, the signal must be assigned a specific intensity from a set range of values (quantization). The original sound wave can now be described using only numbers. When playing, the numbers are converted back into a continuous, analog signal. This electronic signal is then amplified and converted back into a sound wave by a loudspeaker. WikipediADigital Sound Quality
The sensitivity of an electronic water leak detection device is the minimum magnitude of input leak noise signal required to produce a specified output signal having a specified signal-to-noise ratio, or other specified criteria for water pipeline leak noise registration. Sensitivity is sometimes improperly used as a synonym for responsivity. Responsivity measures the slope of a system′s input-output function. WikipediA Sensitive
This innovative device for underground water pipeline leak noise sound detection combines the power of powerful digital signal processing technology and the digital sound quality in a single compact, lightweight buried water distribution pipelines leak sound detecting device that is ergonomically designed to fit comfortably in the palm of your hand.Lightweight
Attention is given to details in digital water leak detector construction that make the buried water pipeline leak noise survey and detection process relatively easy. Purchasing a FlowMetrix instruments and tools is knowing that the water leak sound detction device is based upon sound scientific and patented principles of water leak sound signal registration and digital processing, and not just marketing hype Easy to use
Flat LCD provide highly visible real-time directional instructions. This type of clear, visual cue is bound to command much more attention than a static signLCD for visual cue of leak

Features

Digital Audio Processor:


Audio level compression, also called dynamic range compression, volume compression, compression, limiting, or DRC (often seen in DVD player settings) is a process that manipulates the dynamic range of an audio signal. Compression is used during sound recording, live sound reinforcement, and broadcasting to improve the perceived volume of audio. Wikipedia

Dynamic range compression – accentuates water leak noise sounds, reduces loud noises
Underground water pipeline leak noise detection instruments and devices manufactured by other companies did not include a wide enough spectral range to catch the buried pipeline leak noiseHears water leaks where other instruments cannot detect it
Fundamental control uses a narrow band-pass filter centered about the sweeping sine frequency for estimation of the input signal amplitude. It filters out the effects of ambient noise for the amplitude estimate. It also measures the relative phase between control signals making it possible to do phase-tracked resonance dwells

Precise digital filters block ambient noise
Electrical Interference: Electrical noise induced upon the signal wires that obscures the wanted information signal. Omega.com Automatic rejection of electrical interference (60dB)
