In-situ Impact echo tests for buried pipe

I'm a student and I’m working on Impact Echo for pipes. I have some questions regarding in-situ testing of buried pipes. We are planning to do some field experiments on buried storm sewer and I was just wondering whether we could use our hand held equipment, which is labor-intensive, for the whole 1500 ft pipeline we are planning to test. There must be some scanner kind of small roller-mounted automated device which comprises of impactor(s), receiver which will be accompanied by data-acquisition system. I'm not sure where I can find such info. I’d very much appreciate if you could give some information, pointers where I can find such information.

Thanks in advance,
Chetana.

Another option is Olson Engineering. They have a device that can be used on curved surfaces, specifically for concrete pipes. The system is based on IE. I have not seen any soller sensors for concrete applications which could enhance IE testing.
