Leakage monitoring

A leak refers to a leak in pipes and vessels through which substances, such as gas, can escape. In order to ensure plant safety, minimize product losses and prevent environmental damage, early detection of leaks is extremely important. Leakage monitoring with leakage warning systems or leakage monitoring systems is used for this purpose. To prevent leaks, annual pressure and vacuum monitoring is mandatory.

Field of application of leakage monitoring

Double-walled vessels and tanks as well as double-walled pipe systems, above ground and underground.
For substances that pose a risk to the environment, machinery and people.

Why leak systems?

Leak warning systems provide early information about a leak and enable rapid action. This is essential, especially in the case of hazardous substances and in view of the Water Resources Act (WHG). EX plants (potentially explosive plants) are doubly protected with a specific collection container, so that the risk of groundwater contamination is further minimized.

Different leakage warning systems

There are various options for leakage monitoring. On the one hand, a leak can be detected with the help of a control fluid. In doing so, in the event of a leak, the liquid level within that container would drop and trigger an alarm.

Alternatively, vacuum leak detectors can be used. These create a negative pressure within the interstitial space. In the event of a leak, a drop in negative pressure is then indicated and an audible signal is also triggered.

Similar to the vacuum leak indicator, there are also pressure leak indicators, which are often used for pressureless double-walled containers. The pressure is generated with air or nitrogen inside a control room and must in any case be higher than the pressure of the substance being stored. A drop in pressure would then indicate leakage and trigger a signal.

PURPLAN performs pressure and vacuum monitoring for the purpose of leakage monitoring.

One time scan or permanent sensor technology?

Leakage monitoring is a permanent solution, as the sensors always measure the liquid level or alternatively the pressure or vacuum. In case of leakage, a visual and or an acoustic alarm is always sounded.

Leakage monitoring of double-walled pipes and double-walled tanks

In the case of double-walled pipes and double-walled containers such as oil tanks, leaks on the inner wall would only be detected too late. In this case, the leak detection systems mentioned above offer an optimal solution, as they indicate leaks on both walls.

Leakage monitoring for water pipes

In addition to the monitoring of pipes, tanks and other containers, the leakage warning systems are relevant in the control of water pipes for private households as well as in the industry. The main focus is on preventing water damage and water wastage.
