Smart Pipe Monitoring – SENSOR DDS® LID

A REVOLUTION PIPE MONITORING TECHNOLOGY !

a

      Generally we have three methods of monitoring pipelines.

    • NEW SENSOR DDS® LID Technology is revolutionary linear sensor for long term monitoring of pipelines developed and recently patented by Sensor. With LID technology we can monitor new pipe installations regardless of the type (metallic, plastic, ceramic etc.) and size. The installation is very easy and precision of leak localisation is incredibly high.
    • SENSOR DDS® ERT method of monitoring pipeline integrity on existing  plastic pipelines. Our ERT technology is the only one in the world who is able to monitor up to 20km of pipeline from one access point at once. This makes it the fastest method of testing pipeline integrity in the world!
    • SENSOR DDS® ERT monitoring pipeline integrity on new plastic pipe installations. Works on any non-metallic pipes with any diameter and also we are able to test up to 20km of pipeline at once. We are using special sensors with standard spacing of 2-5m but 10m could also be applied depending on site conditions and resolution required.

SENSOR DDS® LID

The LID method avoids all of the issues of historical leak detection and location techniques by avoiding all traditional parameters and instead directly measuring for leakage in the electrophysical properties of the ground around the pipe.

THE BIGGEST BENEFITS OF NEW SENSOR LID TECHNOLOGY:
– Not affected by noise
– Not affected by pressure
– Not affected by pipes
– Not a skilled process
– It is a definitive result
– Testing process very fast
– Multiple leak detection (in close proximity)

MONITORING NEW PIPE INSTALLATIONS

The best time to install the LID system is at the same time as the pipe itself. Pipes often leak from the moment they are covered for a wide variety of reasons. Installations with new pipes are very low cost and will allow the maximum lifespan of the pipe itself to be. Large pipes require multiple sensing elements.

Sensing Element (SE) positioned on pipe bedding

Installation is simple and unskilled, the sensing element simply needs to be placed close and approximately parallel to the pipe it will monitor.

EASY AS: 123

COMMISIONING & OPERATION

The commissioning takes place after covering.

When connected to the sensing element the system automatically aquires: the GPS coordinates; the exact length of the SE; and a baseline measurement which is stored in a database & associated with an ID chip contained within the buried sensing element.

Either during commissioning or at some point in the future it is recommended that leak simulation tests are carried out. The efficacy of the system is tested & providing the highest confidence. The tests can be achieved using secret valves, soaker pits, or other means to simulate the presence of leakage.

Operation of the system is automated making it simple and fast, each time a transceiver is connected to a sensing element it performs a preprogrammed routine.

ID & GPS position of the sensing element are automatically acquired so that the Leak Location Practitioner does not need to record this information manually. Similarly baseline and any previous measurements are automatically compared, with leak positioning information calculated by linear distance from the GPS position of the measuring station. The average daily testing rate for field testing is around 20km per day.

MONITORING EXISTING PIPE INSTALLATIONS

The string of sensors are installed at a nominal depth of around 300mm, the path of the sensor line needs to follow the path of the existing plastic pipe beneath. For continuous monitoring of other then plastic pipe please refer to our SENSOR DDS® LID technology.

As the only technology in the world, we are able to install up to 1 028 sensors from one point. With sensor spacing up to 10m it gives us 10km in each direction so 20km in total for both directions from single access point.

After sensor line installation, we monitor the geoelectrical properties in subsurface and around the pipeline. Variations in geoelectrical properties underground allow us to create a map of resistivity (or conductivity) and continuously monitor it. Any change in resistivity in near vicinity of the pipe will allow us to detect and locate the leak immediately. Resolution of the leak localisation depends on the sensor spacing. The less spacing between the sensor, the more accurately we’ll be able to locate the leak.

MONITORING OF NEW PIPE INSTALLATIONS

The string of sensors with desired spacing are installed near the pipe. The monitored pipeline must be plastic. If you wish to monitor a metallic pipe, please choose our SENSOR DDS® LID linear sensor.

As the only technology in the world, we are able to install up to 1 028 sensors from one point. With sensor spacing up to 10m it gives us 10km in each direction so 20km in total for both directions from single access point.

Also as with monitoring of existing pipelines, even for new pipelines with Sensor ERT technology we monitor geoelectrical properties around the pipeline. Variations in geoelectrical properties underground allow us to create a map of resistivity (or conductivity) and continuously monitor it. Changees in resistivity around the pipe will allow us to detect and locate the leak immediately. Resolution of the leak localisation depends on the sensor spacing. The less spacing between the sensor, the more accurately we’ll be able to locate the leak.
