此高精度声学检测仪使用 Gassonic 超声波技术，即时检测带压气体泄漏。即使在传统气体检测方法不适用或者依赖于通风时，此检测仪仍可工作。它采用的人工神经网络 (ANN) 技术可将真正的气体泄漏与误报源区分开来，不需要任何的现场培训。Observer-i UGLD 提供了长达28米的检测范围，减少了所需的检测仪数量。它非常适用于复杂的户外管道系统。

• Ideal for use in complex, outdoor pipeline systems - unaffected by wind, gas dilution, and direction of gas plume
• Artificial Neural Network (ANN) technology distinguishes real gas leak noise from background noise, suppressing false alarm sources
• Does not require in-field training, fully operational after installation
• Detects gas leaks from 2 BAR (29 psi) pressure for rapid detection of small gas leaks
• Patented Senssonic™ self-test function ensures full fail-safe operation
• Trouble-free maintenance and one-person check and calibration
