The Internal Based Leak Detection System

There are two types of leak detection systems. One of which is the external based leak detection system and its opposite, the internal based. Both have different ways of detecting leaks but the internal based LDS is the one commonly employed by factories because of the system runs as the internal based LDS monitors leaks through the use of instrumentation devices. There are a few advantages to the internally based LDS including that it is easier and cheaper to acquire and install as it still makes use of recent technology. The internal based leak detection system branches out into several types, one of which is the pressure/flow monitoring method.



The pressure/flow monitoring method of leak detection is perhaps the simplest of all types of the internal based LDS. The pressure/flow monitoring method simply takes note of either the pressure or the flow of the liquid in the pipe as the slightest change in the reading can already determine if a leak is present. One drawback to this system however, is that it cannot be applied for flowing liquid that varies every now and then because this will result in erratic readings.

Another noteworthy internal based LDS is the acoustic pressure waves. What the acoustic pressure waves method does is it takes note of the declining pressure in the pipes. This pressure signifies that a leak is present in the pipe and will automatically send out a notification of the situation. The advantage for the acoustic pressure waves method is that it is very accurate in terms of detecting leaks. However, the downside to it is that detecting future leaks will be difficult to do afterwards.

In contrast to the pressure/flow monitoring method, is the Real Time Transient Model method. The Real Time Transient Model, shortened to RTTM, is a leak detection system that backs up on the ideals of the laws of physics regarding mass, momentum and energy. In effect, the RTTM precisely monitors the properties that need to be monitored in a pipe, such as flow and pressure. While the RTTM is perfect for transient flow, it can also monitor steady flow of a liquid which makes the RTTM highly versatile and a preferred option for monitoring leaks and other important details. The RTTM method has an upgraded version called the Extended Real Time Transient Model or the E-RTTM which adds statistics to its data gathering and monitoring scheme.
