Hi guys,
I am new here. I would like to have your kind help to assist me in my project. Actually, I was currently doing my Final Year Project for my study in university.
My project title is design + setup a tool which capable of detection and location of leak in designed pipeline.
To make it short, now I'm in the phase of identification and selection of components for my device.I would glad to have your opinions in which preferable type of sensors to be purchased in my project
The components selection criteria are as attached :
Basically I want to find for sensors using for :
1. Leak detection in pipe (acoustic sensor)
2. Leak location in pipe (accelerometer/GPS sensor)
3. Tracking device in pipe (accelerometer/GPS sensor)
4. Different pressure as leak occurred in pipe (differential pressure sensor)
info@pipe specs:
Pipeline diameter : 4 inch || Length : 5 meter
Navigation through hydraulic/water flow as it is a free floating device - propelled by pump
The pipe is on the surface (actually it is a pipe loop with some inclinations angle). It is constructed for the experiment purpose.
No detectable odor as it is water flow
No hazardous or corrosive liquid/gas used
The designed pipe is on the lab and used to test the tool capable of detection and location of multiple 'designed' leaks. The tool will run + floating in the pipe upon launch and retrieve at the end of loop..
I'm not really sure if GPS is the best sensor to locate the device during the run. What would your say?
Your attention and help is highly appreciated.
thank you!

What kind of pipe is it? GPS will not work inside a metal pipe.

Re: Sensors Suggestion for Leak Detection in Pipeline
The pipe will be used is PVC pipe

Re: Sensors Suggestion for Leak Detection in Pipeline
You can probably get a GPS signal through PVC. But GPS location resolution is only down to a few meters though. If you have a 5M loop, the GPS is not going to be able to resolve a very precise location in that loop.

Re: Sensors Suggestion for Leak Detection in Pipeline
noted with the GPS thing. I will figure them out soon.
the other important thing is I want to find for type of sensors(may compatible with Arduino or AdaFruit) related to my project using for :
1. Leak detection in pipe (acoustic sensor) - type?
2. Leak location in pipe (accelerometer/other recommend sensor) - type?
3. Different pressure as leak occurred in pipe (differential pressure sensor) - type?

Re: Sensors Suggestion for Leak Detection in Pipeline
We have a variety of accelerometers that are compatible with the Arduino. Our pressure and acoustic type sensors are not designed for fluid use..
Obtaining the raw sensor input is generally a straightforward thing. Processing that raw data to identify a leak is another story, and acoustic data in particular may require signal processing capabilities beyond what is possible with an Arduino.
I moved this thread to General Project Help so that it is more likely to be seen by someone with experience in leak detection techniques.

Re: Sensors Suggestion for Leak Detection in Pipeline
I'm afraid if I misunderstood you. The sensors I;m going to use is not to be 'run' in the pipeline together with the fluid. But the sensors are install or setup in a specific tool. That tool is actually running in the pipe. I hope it clears out thing.
what i understand that the acoustic can identify the specific noise or signals as the leak occurred. If that so, it helps me later to identify, 'yes there is a leak here'.
my concern here is what type of acoustic sensor to be used ? huhu

Re: Sensors Suggestion for Leak Detection in Pipeline
We have microphones and microphone amplifiers. But sound propagates differently in fluid than in air. The acoustic vibrations will be altered and attenuated by any enclosure that separates them from the fluid. I am not an expert in the field, but I think you would be better off using a hydrophone.

I know this is kinda of an old post, but I was wondering if you managed to get it going..
Had an idea...if the device is running the length of the pipe and has a good accelerometer , cellular communication, and gps capabilities, would
it be possible to a) detect an approximate gps position and set generic position variables X/Y/Z to 0..then do some math according to how fast and what direction it is moving in the pipe, and send messages back to and hand-held device for more precise location (if it detects a leak, it send signal-code to indicate leak along with location data that it estimates using gps data of starting point +/- X/Y/Z from accelerometer)
Just wondering if that might be possible and if such a thing would be helpful for your project.
Can't wait to hear about an update on this!
Thanks!
