<p>Leak Detection and Repair (LDAR) is a systematic process for finding and fixing unwanted releases (leaks) of liquids, gases, or energy from pipes, tanks, and equipment, crucial for industries like oil/gas and water utilities to ensure safety, meet environmental regulations (like EPA rules for VOCs), save costs, and prevent asset failure. Techniques range from simple water meter monitoring to advanced methods like acoustic listening, thermal imaging, tracer gases, and drone imaging, with repairs following detection to restore system integrity. &nbsp;</p><p><br><strong>How it Works</strong><br>Detection: Using specialized tools to find leaks.<br>Monitoring: Tracking leak severity and frequency.<br>Repair: Fixing the component to stop emissions/losses.&nbsp;<br><br><strong>Common Detection Methods</strong><br>Acoustic Detectors: Listen for sounds of escaping fluid (water, gas).<br>Thermal Imaging: Detect temperature changes caused by leaks.<br>Moisture Meters/Dampness Sensors: Identify water intrusion.<br>Tracer Gases: Introduce detectable gases to find hidden leaks.<br>Water Meter Monitoring: Check for continuous flow when all taps are off.<br>Specialized Instruments: For VOC/HAP detection (e.g., in refineries).</p><p>&nbsp;</p><p>&nbsp;</p>
