What tool is used to test the functionality of a steam trap?

The ultrasonic device is the most effective tool for testing the functionality of a steam trap. This device works by detecting the high-frequency sound waves generated when steam escapes through a faulty trap. A properly functioning steam trap will emit a particular sound frequency that differs from the sound produced when steam leaks due to a malfunction. By using an ultrasonic device, operators can identify and assess the condition of steam traps without needing to dismantle the equipment, making it a quick and efficient method of evaluation.

While pressure gauges, thermometers, and manometers each measure different aspects of a steam system, they do not specifically diagnose the operational status of steam traps. A pressure gauge indicates the pressure within the system, a thermometer measures temperature variations, and a manometer assesses pressure differentials. However, these tools cannot provide the acoustic analysis necessary to determine if a steam trap is working correctly or if it is leaking.
