LevelMeter App for SONAPHONE

LevelMeter App for SONAPHONE

When used in conjunction with innovative sensor technology and the LevelMeter software, your SONAPHONE turns into a multi-functional ultrasonic testing device. The software for preventive maintenance is intuitive to operate and assists you through the entire testing process. 

The LevelMeter software provides you with a comprehensive measurement and analysis solution for the following applications:

Testing - documenting - evaluating

1. Performing the test

The received ultrasound signals are processed by innovative airborne and structure-borne sound sensors. The measured data is shown by the LevelMeter software in the form of a spectrogram and a level curve on the display.

  • Broadband analysis of the ultrasound signal in a frequency range from 20 to 100 kHz
  • Graphic display of spectrogram and level curve on the display
  • The following measurement levels (in dB) can be selected:
    L – Instantaneous level
    LF –  Instantaneous level with time weighting
    Lpk – Peak level
    Leq – Equivalent continuous sound level
    Lmin – Minimum Ievel of instantaneous level
    Lmax – Maximum Ievel of instantaneous level
  • Integrated infrared temperature sensor in the structure-borne sound sensor
  • Individually adjustable process for making signals audible (phase vocoder/heterodyne)
  • Use of high-quality noise-protection headphones (noise-canceling)

2. Adding additional information

The LevelMeter software guarantees the simple and structured documentation of your measured data. You can also optimize your documentation thanks to the option of adding photos, text comments and voice memos.

  • Simple recording and saving of measured data
  • Quick recording of photos with the integrated camera and marking of potential weak points
  • Integration of text comments and voice memos to supplement your test data

 3. Evaluating the measured data

After your testing procedure, you can create a professional evaluation for management or your customers with just a few clicks. 

  • Export the data as a ZIP file for further processing in your maintenance software
  • Clear summary of the testing procedure in a PDF report: Visualization of the recorded spectrograms and level curves, including text comments and recorded photos

We offer the DataViewer software as supplementary software for your computer for the analysis and management of the recorded measured data. 

LeakExpert - application-specific software for leak detection and evaluation

LeakExpert - application-specific software for leak detection and evaluation

With the SONAPHONE ultrasonic testing device, the innovative airborne sound sensor and the LeakExpert software, not only can leaks in compressed air, gas and vacuum systems be detected, but simultaneously evaluated as well. Based on methods of aeroacoustics, SONOTEC has developed the world’s first process for the classification and evaluation of leaks. The leak is displayed in liters per minute at the touch of a button. You can then use this information to set priorities for repair. The software, which has been specially developed for leak detection, also has integrated test routines that guide you through the measurements. 

The integrated documentation functions allow for state-of-the-art maintenance management. All maintenance-relevant information about a leak is stored directly in the SONAPHONE database. Paper records, which are error-prone and above all laborious, are therefore a thing of the past. Your measured data can be exported in just a few steps in order to be maintained in your existing system. You can also create a PDF report in no time at all. This allows you to contribute to your company’s success thanks to cost savings and increased energy efficiency. 

Leak detection – loss assessment – documentation – evaluation

1. Leak detection and assessment of the loss

Leaks in compressed air, gas and vacuum systems lead to air flows that can be located using ultrasound. The SONAPHONE testing device makes the ultrasonic signals audible and simultaneously shows them on the touchscreen. With various attachments for small and large distances and the graphic display of spectrogram and level curve, you are optimally equipped for leak detection and evaluation.

  • Broadband analysis of the ultrasound signal in a frequency range from 20 to 100 kHz
  • Graphic display of spectrogram and level curve on the display
  • Individually adjustable process for making signals audible (phase vocoder/heterodyne)
  • Use of high-quality noise-protection headphones (noise-canceling)
  • Evaluation of the leak at the touch of a button, and immediate display of the loss in liters per minute. 
  • Automatic classification of the leak size in order to estimate the savings potential

2. Documenting the leaks

The LeakExpert software guarantees simple and structured testing and documentation. Test paths can be defined by entering the building, area, system and component, and help to locate leaks quickly during repair work. You can also add additional information in the form of text comments and voice memos, and take photos with the integrated camera.

  • Simple organization and management of the leaks thanks to the clear structure in the device
  • Individual prioritization of the individual leaks
  • Storage of detailed information on the repair and option to add voice memos
  • Quick recording of photos with the integrated camera and marking of potential weak points +

3. Evaluating the measured data

Save time not only when recording but also when evaluating your measured data. With just a few clicks, you can create a professional evaluation for management or your customers at the end of your testing procedure. The different export functions make it easy for your to integrate the measured data into existing maintenance software. A PDF report can also be created of your work, summarizing all of the data in a structured manner and showing it in the form of diagrams.

  • Simple transmission of the test data to your maintenance software by exporting a CSV file (text file of the data for further processing)
  • Clear summary of the testing procedure in a PDF report: Processing the measured data in diagrams with information relating to the total loss. Clear listing of all saved leaks including text comments, photos and repair information
  • Option to create a ZIP file to backup all test data (including sound files and photos) 

 

 

Innovative Ultrasonic Sensors

Innovative sensors pave the way for new domains of use. While other ultrasonic testing devices can only find leaks, SONAPHONE can also be used to classify the leak size at the same time. Based on methods of aeroacoustics SONOTEC developed a completely new process for classification and evaluation of leaks. The result of the methods are plausible values for the classification of the leak size and for estimation of the savings potential.
