  • Page 25: Method For Water Leak Detection

    6. Method for water leak detection [Hardware] When water leak occurs from a water pipe buried under the ground, the water jets out with force because of the water pressure in the pipe. Such water leak accompanies compound sound involving four elements,i.e., (1) water flow sound, (2) impact sound, (3) to-pipe friction sound and (4) pipe vibration sound.
  • Page 26 6. Method for water leak detection [Hardware] <Conditions that affect water leak detection> 1. Scale of water leak (size of water leak hole in the pipe) 2. Water pressure 3. Soil quality 4. Pipe material grade 5. Pavement type 6. Hydrous soil conditions 7.
  • Page 27 6. Method for water leak detection [Hardware] <NR system> This function permits reduction of transient undesired noise that lacks continuity. High effect is obtained when the set level is elevated. There is a certain time-lag (silent time) in the NR mode before sound is heard through the headphone since the sound hearing switch was pressed.

  • Page 28: Method For Use In Correspondence To Situation Of The Field

    7. Method for use in correspondence to situation of the field [Hardware] <Filter selection> (1) In a place where undesirable noise such as electric pole transformer sound, commercial frequency sound from automatic vending machines, passing sounds from pedestrians’ and automotive vehicles and barking dog is excessive, it is possible to more positively pin down the target sound when a combination of BPF+NF+NR processing is applied.

  • Page 32 10. Description of terms [Hardware] Minimum level value This value relatively expresses the minimum value of the vibration level picked up with the sensor during sound hearing. (000 to 999) This value remains unchanged even if the SENS value is changed, if the input is constant. However, if the SENS value was changed, once release the sound hearing switch and then press it again.
