Embedded Pipeline Leakage Position and Detection Instrument



  SPLD3 pipeline leak detection instrument is specially used in pipeline and valve leakage detecting. It is equipped with on-site real-time detection and positioning function which is wireless. The whole system is composed of two acquisition cards、two sensors、one acquisition machine、one desktop computer , and can realize collecting datum in –real time、storing and analyzing the datum.

Once the high-pressure media sprays out of the leakage pipeline, it produces sound signals and the signals spread along the pipes while the friction takes place at the leakage port. SPLD3 series use the sensors which are placed beside the two leakage points to pick up the sound signals , do wavelet analysis 、 digital filter processing according to the sound signals. Through relative analysis, get related information which includes exact position of leakage source、leakage equivalent and so on.

SPLD3 series is applicable for pressure pipeline leakage detection and position、valve leakage detection and so on. It is especially used in embedding pipelines,in order to avoid blind excavation. The material of pipe wall can be metal、plastic and so on, the pipe media can be liquid、gas and gas-liquid mixture.


Main characteristics

Acquisition rate can achieve 100KHz, and can be set downstairs automatically

Visa radio station, the collector and collecting host is time synchronized;visa wireless WIFI, it can upload the datum

It can collect datum and analyze them with high speed rate and high-precision, it can collect wide-spectrum signals, effective transmission band width can achieve 1MB/s

This series is with high sensitivity and dedicated usage, can collect weak signals from long distances, and the testing scope is wide.

The collector is small, so it is easy to install and take away, is applicable for detecting on site.

The collector is small, easy to take and, thus is applicable for

The collecting and analysis software can support analysis of multiple correlation graphs ,  and automatically calibrate the location of the leakage source according to the collected data.
