5 Procedure for Gas Leak Detection
5.1
Preparation for Gas Leak Detection
1) Using the supplied charger, charge the battery and then insert into the
SN1
(see section 6 “Battery Pack Instructions”).
2) Prepare all items required for the inspection. Items may include tags, piping layout
maps, record/note paper, camera, etc.
3) If necessary, preset
SonicMan
functions as desired (see section 10 “Optional
Settings and Adjustments”)
5.2 Using
SonicMan
, Searching for Leak Locations
1) While listening to the sound output through the earphones, move in the direction of
the source as indicated by
SonicMan
. Adjusting the sensitivity setting (see section
7.4 “Increasing and Decreasing the Sensitivity”) or using the automatic sensitivity
adjustment (see section 7.5 “Using the Automatic Sensitivity Adjustment”) may help
you to locate the source of the leak.
2) Approach the area where the sound is generated and identify the leak location. Use
the nozzle and laser pointer to pinpoint the source of the leak.
5.3
Recording the Detection Reading and Leak Location
1) Estimate the leak level by using the inspection data (see section 8.2 “Estimating
Leakage Level”). By entering the distance and fluid type, 1 of 4 leak levels can be
determined.
2) Save the inspection data and leak level in
SonicMan
’s memory (see section 8.4
“Saving the Inspection Data in the Internal Memory”). A 3-digit record number is given
to the saved data. A total of 310 records can be stored in the
SonicMan
.
3) Attach a tag with the record number to the leak location. This allows the location to be
easily located again for repair at a later date.
4) Take photographs and record the leak locations. Photographs of the tag locations can
assist record keeping and reporting as well as help identify the location at repair time.
Plotting the leak on a piping layout map can further assist this process.
5.4
Reporting Data and Making a Maintenance Plan
1) Recall the saved data from
SonicMan
and make a report along with other data
(photo’s maps, etc.). A report of inspection results can be useful for analyzing the
effects on energy conservation.
2) By referring to the leak levels, make and implement a maintenance plan.
