Leak Detection and Locating Technologies by FUJI TECOM

LC-5000 pinpoints locations of leakage automatically by the arrival time difference between sensors.

• 6 routes simultaneous correlation can be done, and it is shown on one screen.
• 4 sensors correlation can approach a leak point in more than two ways and detection accuracy is stable.
• Even if the radio connection between main unit and preamplifiers is not well, you can correlate at site by logger function.
• Timer function allows recorded leakage data to be correlated in different time.
• Recorded leakage data during survey could be recalculated after resetting of pipe information.
• Use of sensors as a relay receiver makes wireless communication distance longer and avoids poor connection due to obstacles.

With digital noise reduction that removes intermittent sounds like barking dogs and passing vehicles. DNR-18: the advanced digital CPU eliminates intermittent interfering noises, like passing vehicles, people talking, and pedestrian footsteps.
Traditional band-pass filters filter continuous noises, such as A/C hum, idling motors, and wind. While traditional filters are very useful, they are not able to filter out the common, intermittent noises with broad frequency ranges.
DNR-18 has optional accessories for water leak "pinpointing" and water leak "surveying".

Graph the leak sound levels at 5-10 spots directly over the pipe. Let the DNR-18's amplifier pinpoint the leak's location for you instead of relying upon your hearing.

LDR-20 water leak detector is highly sensitive and easier to detect leakage sound, and has a compact and lightweight design.

• High Sensitivity
  Sensitivity of LDR-20 is high, and small leaks can be detected easier.
• Various Filter Settings
  With various filter settings, it is possible to finely handle leak noises of wide range of sounds.
• Compact and Lightweight Design
  Due to its compact and lightweight design, it reduces the load for long term leak detection work.
• Reversible Design
  The operator can flip upside down the LCD display and change the direction of the connections for the pickup sensor etc. to either side by a simple operation.
• Mobile Phone (Android) App
  By mobile phone application, locus display, data display, report output and leakage sound recording are available.
• LDR-20C (Exclusive model for China) available.

The LD-7 is the smallest and lightest-weight water leak detector yet it has a very sensitive ground sensor. With the listening rod connected to the ground sensor, listen to the sounds of water-leaks transmitted to faucets, meters and valves.
Whether your needs are for water leak surveys or for water leak pinpointing in service lines or in buildings, the LD-7 offers excellent performance at a very reasonable price.

The FSB-8D is a small, compact electronic sound detector for finding water leaks.
Especially, FSB-8D is well-suited to Water Leak Surveying on pipe of Plastic pipes like PVC and PE.

To use Fuji Leak Noise Level Logger FSJ-1, FSB-8D leak survey tool is necessary.
The FSB-8D electric listening stick is “Rod Based” acoustic listening instrument for listening for water leaks at meters, valves and hydrants.
The Fuji Leak Noise Level Logger FSJ-1 records noise levels from the FSB-8D to judge if the pipe has a leak or not. The FSJ-1 gives the same result even if the operator is inexperienced for Leak Detection on PVC lines.

USE for
Best for house connection survey to check the service connection has a leak or not.
Check any valves & hydrants for leak sounds.
For Localization of Internal Leaks

• Just push on/off switch, hold for 3 seconds. Easy operation to record noise level at any pipe fittings or house meters.
• Automatically rates to 3 levels. The recorded noise level appears as 3 levels, the threshold is also adjustable.
• For PVC/PE pipe leaks. The frequency peak and the filters are pre-set for plastic pipes leaks.

Simple and light Measuring Wheel B20-s can measure up to 10,000m at 10cm graduation.
The counter is indicated in 5 digits and has reset button. When we use Leak Noise Correlator LC-5000, we need to input the between pick-up sensors.

Fuji Listening Stick is the oldest products among Fuji Tecom's over 60 years history, at the same time, this is also one of the most effective tool at leak surveying.
An optimum designed resonance chamber amplifies the leakage noise from various kinds of pipe materials including non-metallic pipe.
Light, thin, compact design reduce burden on investigation.

• Standard model with golden head parts.
• 'Fuji Floating System' makes sound louder than conventional model.

• High sensitivity model with titanium gray head parts.
• Tuning folak mounted in head part makes the sound clearer (Patent No. 6153418).
• Entire part is strengthened, and bar part is magnetized.

• 3-section contact bar with head of LSP.
• Separable into 3 parts and carried compactly.

After marking the leaking point on the ground, make a hole at the marked point by use of the boring bar and insert the Listening Stick into the hole to confirm the leaking point as near as possible.
Fuji boring bar saves you excavation cost.
