The frequency of operation of a steam trap is governed by

The operation frequency of a steam trap is directly influenced by the steam pressure in the line. Steam traps are designed to allow condensate and non-condensable gases to escape while preventing steam from escaping. When the steam pressure in the line is higher, it can lead to increased temperature and greater production of condensate as the steam cools down and condenses into water. Therefore, higher steam pressure typically results in a more frequent operation of the steam trap to manage the increased amount of condensate effectively.

While the amount of condensate formed is indeed a factor, it is closely tied to the steam pressure since it affects the temperature and efficiency of steam usage. An automatic timing device wouldn't accurately reflect the dynamic operation of the trap, as steam systems operate based on real-time conditions rather than timed intervals. The size of the steam line might influence the flow properties, but it does not govern the operational frequency of the trap directly as steam pressure does. In summary, understanding the relationship between steam pressure and condensate formation is crucial for maintaining efficient steam trap performance.
