Thermal Imaging and Remote ...

Thermal Imaging and Remote Sensing using Satellite imagery technique (such as Utilis) have been tried.  However, drone technology could be compared with the thermal imaging using helicopters.

THe success much depends on the accuracy of pin-pointing leakpoints and just finding areas of likely leakages is not so important to arrest losses.  Therefore the accuracy should be +/- 50 cm, i.e. half of the pit width.  Also how many invisible leaks are in the system?  It should be found what is the efficacy of locating invisible leaks.  If the pressure in the system is low to the tune of about 1 kg/cm2, it will be worth continuing with the conventional electronic equipment.  In any case, the conventional equipment can't be set aside.

Now a days, some people are also claiming that leak detection is possible through hydraulic modelling. One should weigh such claims vis-a-vis the usual methods in vogue ans ask the modellers to come and detect leaks for you at site.

Kindly Note : THERE ARE NO SHORTCUTS TO LEAK DETECTION AND BUILDING UP PERSEVERANCE IN THE TEAM IS IMPORTANT.
