Ultrasonic Leak Detectors

Ultrasonic leak detectors are devices that use high-frequency sound waves to detect and locate leaks in pressurised systems. These devices work by detecting the high-frequency sound waves produced by leaks in pipes, valves, and other equipment. Ultrasonic leak detectors are invaluable tools for maintenance personnel, allowing them to quickly and accurately identify and repair leaks in various applications.

This is because many ultrasonic leak detectors are highly sensitive to sound and feature LED displays and audible indications. These LED displays can provide visual feedback on the size and location of leaks. At the same time, audible indications can alert users to the presence of leaks, enabling users to gain immediate feedback on the presence of leaks and the extent of their severity.

Some ultrasonic leak detectors also feature adjustable sensitivity settings and automatic background noise compensation, allowing users to customise their settings to suit specific applications and environments. Users can also calibrate the leak detector to isolate the specific sound frequency of the leak, filtering out wind noise, voices, traffic, and most normal operational sounds. These features can make it easier and more efficient for maintenance personnel to detect and locate leaks, ultimately saving time and money on repairing equipment.

Benefits and Features of Ultrasonic Leak Detectors

Beyond facilitating maintenance personnel with identifying and managing leaks, leak detectors offer several other benefits.

Non-Invasive

Leak detectors can locate leaks without damaging equipment or interrupting operations, making them ideal for use in sensitive areas.

Time-Saving

Leak detectors can locate leaks quickly, reducing the time and cost of repairs while preventing major issues, which helps minimise downtime and keep operations running smoothly at peak performance.

Versatile

Ultrasonic leak detectors can be used to detect leaks in a wide range of applications, including compressed air systems and refrigeration systems.

Applications of Ultrasonic Leak Detectors

Ultrasonic leak detectors are widely used across various industries in New Zealand. Some of the common applications include:

• Compressed Air Systems: When compressed air escapes through a leak, it creates turbulent flow and a high-frequency hissing noise. While this hissing can be heard in a quiet environment, it is nearly impossible to detect amidst the noise of production. However, ultrasonic leak detectors can identify noise fluctuations from pinhole leaks with pressure as low as one psi using acoustic sensors. These detectors can also be calibrated to focus on a specific sound frequency, making detecting leaks in pipes, air hoses and valves easy.
• Refrigeration Systems: Ultrasonic leak detection methods can also employ sound waves to identify and locate water leaks from fluids like refrigerants. This helps prevent the loss of refrigerant, which can be expensive and harmful to the environment.
• Steam Systems: Ultrasonic leak detectors are valuable inspection tools that provide insight into the condition of various steam system components. These include steam traps, heat exchangers, shutoff valves, control valves, solenoids, relief valves, cavitation in condensate return pumps, and atmospheric steam leaks. Since systems with leaks require additional energy to maintain the same pressure level, too many leaks can cause the system to fail to perform adequately. By preventing energy waste, they reduce the risk of equipment failure and the subsequent domino effect of inefficiencies.
• Vacuum Systems: Detectors are used to maintain the proper vacuum level and prevent contamination.
• Automotive Industry: The detectors are used to detect leaks in engines, transmissions, and other components which helps to ensure vehicles are running efficiently and safely.
