Pinpoint water leaks faster and more efficiently by carrying out multiple leak noise correlations at the same time, or a single correlation between up to ten sensors.

Multi-point correlation

Synchronize and deploy up to ten FIDO sensors around a point of interest and run a single correlation to locate a leak anywhere between them.

Work offline

Carry out correlations in areas of low or no phone signal, ensuring uninterrupted leak investigations. Get verified results next time you’re back online.

Conduct correlations simultaneously

Conduct multiple correlations at the same time. Work across different locations while the correlations are running and come back for the results any time.

Re-run results indefinitely

Refine and re-run correlations between any synchronised sensors if you need to correct details about pipeline material or length. No need to go back to site.

What you need for FIDO leak noise correlation

All you need to correlate with FIDO AI is a minimum of two FIDO acoustic sensors and a subscription to the FIDO app. Our lightweight, versatile sensors can be used in many ways during the leak investigation process and never need charging or calibration.

How to use FIDO leak noise correlation

Leak noise correlation is a process where FIDO AI calculates the location of a leak between two sensors by using the time it takes the noise to reach each sensor. It is generally carried out after a leak has been detected when FIDO AI has mapped the best starting point for further investigations on the water network. It is done immediately after asset sounding, which confirms the loudest leak noise, and before top sounding.

Step 1 Synchronise your sensors

Easily select and synchronize up to ten acoustic sensors using the FIDO smartphone app. All sensors are equipped with a highly accurate digital clock for perfect timing.

Step 2 Choose your locations

Use your smartphone app to find or identify locations on your network where you want to place your sensors. The app guides you through each deployment.

Step 3 Upload your data

Run one or more correlations simultaneously. You can leave sensors to finish recording. They’ll store data indefinitely until you’re ready to collect and upload it to FIDO AI.

Step 4 Review pipeline data

FIDO AI automatically calculates leak locations based on the pipeline characteristics listed in your GIS. Simply re-run results with amended data later if you find an error in your GIS.

Step 5 Get confident results

Every location comes with a FIDO confidence score to help assess the need for more work. If a leak is outside the correlated pipe section, the app will indicate where to correlate next.

Benefits of FIDO cloud correlation

Leak Locate Powered by FIDO AI is designed to make leak investigations simpler, effective and more joined up.

Save time on leak location

Locate leaks faster and more efficiently with endless flexible ways to correlate from synchronized audio samples, including carrying out multiple correlations at once. You aren’t limited to traditional 2-point investigations. With multi-point correlation, you can locate a leak between up to ten locations.

Work confidently in low or no network areas

You don’t need to be connected to the phone network to set up and run correlations. The FIDO app’s offline mode lets you sync and deploy sensors, sample audio data and configure one or more correlations even in areas of low or no phone signal, ensuring uninterrupted leak investigations. Get results whenever you’re next online.

Re-run and refine results any time

FIDO AI stores correlation data indefinitely so you can refine and re-run correlations between any two or more synchronized locations as often as you like – and from any location. This can be useful if you later discover the pipe diameter or material in your GIS was incorrect. You don’t need to go back to site.

Start your correlations right with Network Monitor

The most successful leak noise correlations start with a reliable point of interest for your technicians to investigate.

Use FIDO’s Network Monitor to automatically detect leaks and maps reliable waypoints for all your leak investigations daily.

Your correlation questions answered

How is FIDO AI used in the correlation process?

FIDO correlation combines machine learning with complex mathematical calculations. This minimises the need for complicated, engineered hardware in the field because all the clever stuff is done in the cloud.

How does FIDO’s multi-point correlation work?

Multi-point correlation allows users to synchronize up to ten FIDO sensors and run multiple correlations between any two of them, simultaneously and as often as they like - even later, when they are off site. Once you have the synchronized data, it’s stored forever, so you can reconfigure correlations to run between different points.

We are constantly refining and improving our smart correlation functionality, with plans to launch fully automated remote correlation using our IoT Relays soon.
