Depending on the unit, batteries will last up to 8 – 22 hours. If the battery is low, the red light turns on and the units will soon need recharging.
Yes, they are waterproof. With the cable connected they are IP68 rated and are fully submersible.
Accelerometers are designed for smaller diameter and metallic pipe and geophone are designed for larger diameter and non-metallic pipe. Hydrophones are designed for large diameter pipe including PVC and AC.
- Make sure the sensor is mounted vertically.
- Make sure there is no debris between the sensor and fitting.
- Make sure you are only using it on PVC up to 6 inches and AC up to 12”
- Make sure the dry barrel hydrants are charged when using this sensor.
For both receiver and PC the white sensor is the left and blue is on the right.
Radios can broadcast easily over a kilometer. Through buildings and hills can shorten the distance. Raising transmitters off the ground and correlating from where you can see both transmitters can improve radio quality.
- You can open a hydrant/service between the mounted sensors, to generate a leak and test the system.
- You can test the sensors by performing a ‘scratch’ test. To accomplish this, connect the sensors to the transmitters and plug the headphones to the transmitter/receiver headphone jack. Scratch on the sensor or the fitting the sensor is attached to, and listen to confirm noise is being generated through the headphones.
This is done when you are unsure of the pipe type and size, if it is unknown whether repairs have been done on a stretch of pipe or if the pipe is degraded and so the assumed velocity might be off.
- Attach the two sensors to hydrants/valves and accurately measure the distance between them.
- Create a noise outside of the bracketed sensors (out-of-bracket) by creating a leak or tapping on the hydrant/valve.
- Correlate the noise you just created
- Then click on the velocity calculator at the top of your correlation screen
- Move the cursor to the very top of the noise peak and note the velocity indicated at the bottom left of the screen.
- Then when doing subsequent correlations, click on “methods” in the correlation input window and select “input velocity”. Now you can input the pipe type, sensor spacing and the velocity measurement you just calculated to correlate.
- Make sure receiver is turned on.
- Ensure that the LFRT soundcard (AK5371) is recognized by Windows. This can be done in the control panel.
- Check hardware to confirm that the system is working. (See above)
- Radio interference can cause centre correlation. Confirm by listening on the receiver for static. Move closer to transmitter that has the most static and re-correlate. Things that cause most interference: electrical transformers, conflicting radio transmissions, power lines, DC power sources, and ground-borne noise/vibration.
- Call for support if problem continues
Move sensors to bracket the leak noise. This can be done by leapfrogging the sensors in the direction of the leak noise. Blue station is on the right side of the screen and white station is on left side of the screen interface.
A number of factors can affect the signal to noise ratio. Including the following: some leaks are quieter, there may be no leak, change of pipe material and pipe diameter, tuberculation, PVC repairs, multiple bends, valve keys, debris between fitting and the sensor.
- To increase the quality of the leak noise signal, increase the volume input of the software (or windows input volume)
- Remove impedances, i.e. valve keys
- If sensors are attached on dry barrel hydrants, charge hydrant
- Move sensors closer together if possible
- If change of pipe diameters or materials occur, refer to velocity check (see above)
- Check input information: pipe diameter, material and distance between sensors
- If unsure of input information, a velocity check is required
EchoShore: Advance Transmission Main Monitoring System
The EchoShore system is a permanently installed monitoring system for critical water transmission mains. The system automatically detects leaks and can collect other vital pipeline data, such as temperature and static pressure.
The EchoShore system monitors critical water transmission mains where the risk of catastrophic failure must be reduced. The EchoShore system is designed to find leaks before they escalate to catastrophic failures. Customers demand the EchoShore system because:
- Disruption to surface traffic flow would have a significant negative economic impact.
- A single main carries a large proportion of a community’s potable water.
- Remote mains are under the threat of tampering or 3rd party damage.
The EchoShore node is the basic building block of the system. A node is self-contained and consists of a data logger, communications hardware, power source, antenna, and the Echologics hydrophone. Nodes are spaced along the length of the transmission main to be monitored and are installed in either a manway access chamber or an above ground enclosure. The nodes collect data and wirelessly upload it to a secure server. The data is then analyzed to determine the precise location of the leak event. The operator is then notified via SMS or email, and through the user interface.
Leak detection is automated and occurs in pre-determined intervals. During a leak detection data capture session, the system records high quality acoustic samples from a group of nodes monitoring a specific pipe segment. The files are transmitted over a cellular network to our back-end server for analysis. Correlation is performed in a fashion similar to the LeakFinderRTTM method. While any interval is possible, the typical operating profile is 1-3 leak detection events every week. The more frequent that leak detections are performed, the shorter the battery life.
The design is based on the next-generation, proven LeakFinderRT technology. The EchoShore system can be thought of as a “permanently installed LeakFinderRT”. EchoShore includes multiple design innovations that make it self-contained and automated.
The service provider will be dependent on the country where the system is installed. For the US, the cellular service will be provided by AT&T through Mueller and managed by Echologics. The cost is included in the monthly monitoring fee and will not require any administrative support from the customer.
Over time and depending on the frequency of leak detections, the battery power source will require servicing. Also, as with most sensors, periodic maintenance may be required for inspection and cleaning.
No. All leak detection equipment, sensors, and hardware are outside of the water flow of the pipe.
The node enclosures are designed to be wall-mounted in an existing dry access chamber or an above-ground enclosure. Node spacing approximates air release valve and/or access chamber spacing along a transmission pipeline, so there is no need to construct a new chamber. The Echologics hydrophone requires a standard 1.5” NPT connection to the pipeline, and can be T’d into the air release valve connection.
Depending on installation specifics, traffic control may be required for access chambers.
Transmission Main Leak Detection (TMLD) Questions
For a well trained operator, very accurate (<1foot) providing the physical measurement between the two sensors is reasonably accurate. Given that physical measurement using a wheel may involve a slight margin of error, the goal is to be within backhoe range (3-4 foot range from actual leak).
How accurate is our detection on transmission mains?
This is dependent on the distance between two sensors, however on a detect over 2500’ we are +/-6’
This is dependent on material type, distance, pressure and the presence of other leaks. On a typical 400’ shot we have found leaks as small as .1GPM on an 8” CI main. On transmission mains, we can find leaks as small as 1 GPM at sensor spacing’s up to 3000’ on 60” pipe.
Our preferred distances are between 2000 and 3000’, however we have shot as long as 1.8 miles successfully on a leak of 5 GPM
Condition Assessment Questions
No, corrosion on the pipe tested affects the average minimum pipe wall thickness on the section tested, but specific footage markers are not provided. The pipe section distance can be reduced to gain better resolution on where corrosion may be most prevalent.
The technology works on pressurized force mains but not on gravity fed lines due to a lack of pressure in the system.
Yes. Our technology can assess the structural condition of pipes made from a variety of materials, including Cast and Ductile iron, pre-stressed and pretensioned concrete cylinder pipe (PCCP), plastic, asbestos cement and steel.
Our core technology uses a proprietary acoustic-based leak detection system and a comprehensive proprietary database to assess the structural condition of selected water pipes of all sizes and materials.
