How to detect compressed gas leaks? How to calculate the cost of leakage?

UE ultrasonic leak detector can easily help you solve the problem

Using UESYSTEMS ultrasonic testing technology, we can help you easily and quickly locate the leak location

The principle of ultrasonic leak detection

The ultrasonic leak detection method is mainly based on "sound": when air flows from the high-pressure side of the leak to the low-pressure side, turbulence will be generated around the leak; Ultrasonic detection instruments can detect ultrasonic signals generated by turbulence in the air.

Ultrasonic testing technology can be applied to various types of leak detection, including pressure leaks, vacuum leaks, and any type of compressed gas leakage. Mainly in places with explosion-proof requirements, it is necessary to choose "ATEX" Or explosion-proof certified instruments such as "IS" (intrinsic safety models).

Characteristics of ultrasonic signals:

By utilizing the characteristics of ultrasound waves, leakage points can be easily and accurately located

The directionality of ultrasound:The directionality of ultrasound and the extremely small diffusion angle make it very easy to locate the source

Signal strength:The closer to the leakage point, the stronger the signal received by the instrument

Anti interference capability:The frequency of ultrasonic testing is different from that of audible sound waves and will not interfere with each other, so it can still be used in noisy factory environments!

The efficacy of ultrasonic leak detection

At present, ultrasonic leak detection technology has been widely applied in factory safety, environment, energy conservation, and quality improvement. including:

lower corporate costs:Compressed gas is very expensive, finding the leak point and repairing it can reduce the cost of energy consumption

Energy saving:By repairing the leakage point, an average energy consumption reduction of 31% can be achieved

Extend the service life of the compressor:Reduce the operating time of the compressor, thereby reducing equipment aging and wear and tear

Efficiency improvement:Improve the operational efficiency of compressed gas systems

environment protectionReduce the harm of certain gases to the environment

Safety:Improve detection efficiency and personnel safety, such asLeakage of combustible gases=safety hazard

Steps for Ultrasonic Detection of Compressed Gas Leakage

The usual steps for leak detection are as follows:

1. Simple and fast location of leakage:

A. Prepare the instruments and applicable probes.

B. Put on headphones and turn on the instrument

C. Choose the appropriate detection frequency, UESYSTEMS recommends 40kHz

D. Suitable for scanning probes, scanning along the path where compressed gas may leak, from a large range to a small range, until the maximum point of listening to headphone sound

D. If the leakage point cannot be determined or there is noise interference, adjust the instrument detection sensitivity and repeatedly scan the suspected area until the leakage point is found

E. Some noise reduction methods can be adopted

2. Use leak labels to mark the leak location and record the leak readings using Ultraprobe series digital instruments

3. Use DMS software or mobile leak app to calculate the cost of the leak

How to calculate the cost of leakage?

Automatic calculation by database software

Save the detected data in the instrument, then import it into the computer DMS database management software, create a report on potential energy-saving benefits, and arrange subsequent maintenance activities
