Propane Tank Leak Detection

Project Overview:

Propane cylinders are to be inspected for leaks automatically. The system must be capable of testing 9000 tanks per shift and locate leaks as low as 1x10-³ std. ml/sec.

System Description:

4 each single channel system with 6 each summed microphones, adjustable alarm set points, relay contact closure, white noise sensitivity verification option.

Each propane tank is pressurized with air and sent through a test station. Ultrasonic microphones are placed within an acoustic isolation chamber to prevent false readings from stray ultrasonic signals that may be present in the manufacturing area. Six ultrasonic microphones are positioned around all weld sites.

When a leak is detected the system's reject mechanism is activated.
