METPOINT® LKD: Fast and reliable leak detection

Are you aware that leakage drives up the energy costs in production? However, leaks often remain undetected for long periods, as one mostly cannot see or hear them. Such undetected leaks slowly become real cost drivers. Remedying leaks provides the highest savings potential in the field of compressed air supply. 

Small cause - large effect

Small cause - large effect. Even small leaks can make a big contribution to the costs for compressed air. In total, leakage rates of 30% are not uncommon. In times of rising energy prices, high sums of money therefore “go up in smoke” very quickly. The remedy here is the small and easy-to-use METPOINT LKDLeak Detector. If it is utilised, then the leaks in the system can be located in a short time. Maintenance is therefore targeted accurately and possible at short notice. The METPOINT LKD uses a physical characteristic for this purpose. As compressed air escapes, the gas molecules cause friction along the pipework wall. This friction in turn generates a noise in the ultrasonic frequency range.

The LKD leak detection device informs via color display, measured value and acoustic signal. Compact dimensions and easy operation make it quick and usable everywhere.

Functional principle

Leaks are points in the compressed air system where air can escape. As this results in a pressure drop, more energy is needed to keep the pressure in your system at the required level. Leaks generally occur in towards the end of production on pipework, connections, maintenance components as well as rapid-release couplings.

As compressed air escapes, the gas molecules cause friction along the piping wall. This friction in turn generates a noise in the ultrasonic frequency range. The METPOINT LKD detects this noise and converts it into audible and visual signals. As it only picks up noise within the gas leak frequency range, the device allows for accurate detection even in noisy environments.
