Which inspection apps are available for the SONAPHONE and which app is suitable for which application?

Different apps are available for the SONAPHONE, each designed for specific preventive maintenance tasks.

The main inspection apps are:

• LevelMeter – universal ultrasonic measurements
• LeakExpert – leak detection and assessment
• SteamExpert – steam trap testing with automatic assessment
• AssetExpert – route-based data acquisition and measurement point organization

LevelMeter

LevelMeter is the universal inspection app for airborne and structure-borne sound applications.

Typical applications include:

• machine and bearing inspection,
• monitoring of bearing lubrication,
• electrical inspection,
• valve inspection,
• general leak detection,
• individual ultrasonic measurements.

The app displays the ultrasonic signal, including as a level curve and spectrogram, and also makes the signal audible.

Depending on the connected sensor, different measurement values can be displayed, including:

• instantaneous level,
• smoothed instantaneous level,
• peak level,
• equivalent continuous sound level,
• minimum and maximum levels.

When used with the BS20, temperature can also be displayed.

Measurements can be documented with photos, voice memos, and text comments. Selected measurement data can also be used to create PDF reports or exported for further analysis.

LeakExpert

LeakExpert is the dedicated app for locating, documenting, and assessing compressed-air leaks.

In addition to locating a leak, the app supports quantitative estimation of the leakage loss.

The loss can be displayed, for example, as:

• volumetric flow in L/min or CFM,
• financial loss in € or $.

This allows leaks not only to be located and documented but also to be assessed and prioritized according to their economic relevance.

SteamExpert

SteamExpert is the dedicated app for testing and assessing steam traps.

The app provides a workflow specifically designed for this inspection task and guides the user through the testing process.

When used with the BS20, structure-borne sound and temperature information is recorded. Based on the measurement data and the stored steam trap and operating parameters, an automatic assessment of the tested steam trap is performed.

SteamExpert therefore supports:

• standardized execution of the inspection,
• acquisition of ultrasonic and temperature data,
• automatic condition assessment of the steam trap,
• documentation of the inspection result.

The measurement data can subsequently be organized and evaluated further in SONAPHONE DataSuite. Among other functions, the DataSuite can be used to estimate the steam loss associated with a defective steam trap.

AssetExpert

AssetExpert is used for route-based data acquisition and measurement point organization directly on the SONAPHONE.

The app is particularly suitable for recurring inspections of defined assets and measurement points.

AssetExpert supports functions including:

• processing prepared inspection routes,
• assigning measurements to defined measurement points,
• viewing historical data for a measurement point,
• identifying measurement points by QR code or ID,
• synchronization with SONAPHONE DataSuite.

AssetExpert therefore supports standardized and reproducible condition-monitoring workflows.

Which app should be used?

As a simplified guide:

• general or individually configured ultrasonic measurement: LevelMeter
• locating and quantitatively assessing compressed-air leaks: LeakExpert
• testing and automatically assessing steam traps: SteamExpert
• working with predefined measurement points and inspection routes: AssetExpert

The apps complement each other and, depending on the inspection task, can be integrated with SONAPHONE DataSuite to provide a continuous maintenance workflow.
