Query for steam volume in heat exchanger design, effects of overloading.

Request for help: I have a reboiler in my installation (with steam as the heating medium); currently, the steam flow meter consistently shows values above its maximum range, and the lifespan of this heat exchanger is also relatively short. I’m trying to find the design value for the steam consumption of this heat exchanger, but I couldn’t locate it in the equipment blueprints or the preliminary design drawings. How can it be easily found out? Please let me know. What are the effects of long-term excessive steam volume? !
This falls under process calculations; such data should not be included on the equipment drawings
Thank you very much for continuing to provide in-depth analysis!
The design values are listed in the equipment data sheet
Is a steam trap installed at the steam outlet (condensate outlet)? The steam flow rate is controlled so that it cannot exceed a certain level, unless a large amount of heat is required for reboiling and evaporation, resulting in an error in the calculation of the steam volume during design (the value calculated is too low)
