Using the same acoustic emissions (AE) leak detection technology as Score’s portable valve leak detection tool, the MIDAS Meter®, the MIDAS® Sensor is designed for permanent but non-intrusive installation to provide continuous on-line valve condition and performance monitoring in hazardous areas where intrinsically safe certified equipment is required.

The MIDAS® Sensor detects the early onset of leakage so aiding operations to identify, trend and quantify valve leakage and enabling the appropriate operational and remedial actions to be put in place. 

This intrinsically safe valve condition and performance monitoring solution takes you from reactive to proactive maintenance by engaging in condition based monitoring and predictive maintenance activities. 

MIDAS® Sensor valve leak detection equipment therefore helps pinpoint losses and focus maintenance budget expenditure and actions on valves where maximum benefits can be achieved.
