eXPert LDS.


Advanced leak detection systems.




Products / eXPert LDS


A safe and profitable way to optimize long distance transport of gasses and fluids.

Efficient integration


eXPert LDS can be supplied as stand-alone application or as an eXPert SCADA combined module, from which acquires physical parameters and status of the process, thus ensuring advanced alarm features about presence of leak phenomena and enabling real-time visualization of monitored values to transport system operators.

Optimized models


Potential leak detection is based upon sophisticated engineering algorithms that combinate mass balance (MB) methods with fluid flow rate /pressure waves propagation models (Pressure and Flow – PF), in order to grant maximum available accuracy in load loss individuation in an extended transport network.
