Can the SONAPHONE be used to estimate the steam loss caused by a defective steam trap?

Yes. As part of steam trap testing with SteamExpert, measurement data can be recorded and subsequently evaluated in SONAPHONE DataSuite. The DataSuite provides a function for steam loss estimation.

How is the inspection performed?

The steam trap is tested using the SONAPHONE and the BS20 structure-borne sound and temperature sensor.

Ultrasonic and temperature information is recorded and used to assess the condition of the steam trap.

The measurement data can then be transferred to SONAPHONE DataSuite and assigned to the corresponding measurement point.

What is the purpose of steam loss estimation?

If a steam trap is defective, live steam may pass into the condensate system without being used. Steam loss estimation helps assess the magnitude of this loss.

This can be used to:

• compare defective or suspicious steam traps,
• prioritize defects with a particularly high economic impact,
• plan maintenance activities more effectively,
• document potential savings.

Is the steam flow measured directly?

No. The displayed steam loss is an estimate based on the steam trap inspection and the data available in the software.

It is not a direct flow measurement of the escaping steam.

For a reliable assessment, the steam trap data and actual operating conditions should be entered as accurately as possible and taken into account when interpreting the result.
