Acoustic Wave (Acoustic Emission)
Valve Leak Monitoring and Quantification

Application Scenes:

• suitable for leakage monitoring for various valves and pipelines;
• long term remote unattended condition monitoring;
• difficult or impossible to access object surfaces, e.g. high/low temperature, nuclear radiation, flammable, explosive, or toxic conditions;
• regardless of whether the internal medium is liquid or gas;

Background:
Valve leak is a big threat to industrial productions, always affecting production safety. Corrosion and leakage appear with the extension of the service time of valve. Small leak grows rapidly if there is no effective detection in early stage. It not only causes lots of property losses but also threatens the environment. Therefore, effective early leak monitoring becomes more important today.

Technology Principles:
The acoustic waves generated by the friction between the medium and the fracture of the material propagates along the surface of the material and is received by the acoustic wave (acoustic emission) sensor. The acoustic wave (acoustic emission) system processes and analyzes the received acoustic signals and evaluates the leakage status of the pipelines and valves.

RAEM Online Monitoring System Features:

• Online --- acoustic wave (acoustic emission) monitor is installed on the monitoring objects surface to achieve any time any day of condition monitoring and diagnosis with online and historic data stored and displays.
• Intelligent --- auto process the monitoring data without manual controls; auto alarming for abnormal conditions; auto analyse the leak rate of the pipeline valves; auto analyse the leak areas. The whole monitoring process and result evaluations are automatic.
• Remote --- with the help of the Internet of Things technology, users can obtain the monitoring results of the monitoring points from any unlimited distance ranges at any locations.

System Installation:
A variety of data output communication modes (WiFi, 4G, Ethernet, RS485, etc.) can be configured according to user requirements to achieve the regular scheduled detection or long-term monitoring detection and other application modes.
