Non-Invasive Valve Leak Detection, Quantification & Trending

Page last modified
February 22 2024

It is known that leaking valves represent a major environmental and safety risk and are a major source of lost profits. Find leaking valves quickly and easily with Score's MIDAS Meter® Acoustic Emission Leak Detector long before detection by conventional methods or instrumentation!

Completely portable and easy to use, the MIDAS Meter® uses an acoustic emission (AE) sensor which finds and quantifies through-valve leakages by examining the very high frequency noise a leaking fluid generates. This valve leak detection tool quickly finds leaking isolation valves, control valves, check valves, PSVs and steam taps, allowing  personnel to benchmark valve performance during commissioning or operations and provides data storage, analysis and reporting in the field, via an instrinsically safe certified smartphone.

This state of the art valve condition and performance solution takes you from reactive to proactive maintenance, by engaging in condition based monitoring and predictive maintenance activities. MIDAS Meter® valve leak detection equipment therefore helps focus budget expenditure and actions on valves where maximum operational benefits can be delivered.
