Function : Ultrasonic leak detection
The ultrasonic method is more accurate to analyze and check steam traps. The ultrasonic waves in the traps are converted into audible sounds (heterodyne function). Steam traps usually work cyclically. In the traps there is a valve which is closed when steam is in – no ultrasound produced – and the valve opens when filled with condensate – presence of ultrasounds – .
The length of a cycle depends of the load , pressure and type of steam traps. When listening to these cycles, the processor inside the LEAKSHOOTER analyzed the ultrasound detected and is able to check if the steam trap works or not.
