Valve Leak Detector Received Positive Reviews

We’re thrilled to share glowing feedback from a customer who evaluated our SVLD1 Valve Leak Detector, powered by advanced acoustic emission technology. Their positive review is now available for broader distribution!

“I used the SVLD1 today at a customer's geothermal power plant. The meter did exactly what I was hoping and helped to identify sources of ultrasonic noise emissions - examples shown below of a steam trap in operation.

This explains the root cause of issues which my customer has had with ultrasonic flow metering for some years.

Resolving the issue is another matter, but at least we have a better understanding now.”

Steam Trap

67.1 dB peak - just prior to actuation
 

Steam trap where samples were observed
 

46.5dB
Showing strong emissions around the frequencies relevant to the ultrasonic flow meter.
These frequencies were observed to be able to propagate along metallic pipework.
 

Flow Meter Signal

The peak on the left is 43.1 dB - attributable to the flow of water.
The distribution around 50 kHz is the flow meter sampling.

Other Sources of Emissions

At adjustment valves and NRV
71.5dB


Water Injection Nozzles (into geothermal steam)
62dB
