INSERTION AND LAUNCH
Launch at T-fitting with Piston Potable Water Insertion Point
Via existing fittings by means
of a provided insertion sluice
The fitting diameter must be
at least half the diameter of
the pipe.

RETRIEVAL AND REMOVAL
Retrieval at Gated T-fitting Potable Water Extraction Point
Via existing fittings, or a
retrieval method that
includes an inserted
capture net

PIPE-INSPECTOR FOR WATER
• Floating in the pipeline fluid without external cable connection
• Inspection without operational interruption
• Optical representation of the pipeline interior in HD
• Location of minor leakages (2.5 gal/h at 70 psi) even in large
diameters
• Pressure recording over the whole pipeline length
• Inspection of long sections (10 miles /day) with only one access
point
• Permanent device tracking
• Easy data evaluation
• Monitoring of the lifetime condition by repeated inspections

INSPECTIONS
• Flush / Clean the forcemain to ensure useable HD-
CCTV video of the submerged interior wall
• Insertion and Retrieval method may be non-

• For best results of CCTV, clean water should be
used if possible.
• CCTV, Acoustic Leak, Temperature (I/I), distance
• Multiple bends allowable
• May reveal deposits

CONCLUSIONS
• A battery powered, untethered in-pipe device that floats
with the pipeline fluid can provide synchronized data not
limited by tether length or vertical and horizontal bends
during live flow operations.
• A cylindrical design enables stable movement and not
tumbling deployments and allows an assembly of accepted
pipe inspection sensor technologies to be synchronized
and correlated.
• By matching inspection tool size to pipe size ensures
quality video and data collection.
• MSI for pressure pipes is a cost-effective solution to
pipeline owners by minimizing deployments of numerous
sensor specific devices.
