Sizing from a demand profile instead of an average flow

01Record a representative cycle

A shift-average flow can hide short, high-demand events. Log the gas use over a complete production cycle and identify which machines run together. Retain the sampling interval: a slow logger can smooth away the very peak the supply system must handle.

02Distinguish sustained and transient loads

A sustained increase needs production capacity; a short event may involve suitable buffering and recovery between events. Record the minimum pressure tolerated during each event and the time available for replenishment. Neither solution can be selected from the peak number alone.

03Test the proposed operating pattern

Ask the supplier to explain how the system handles startup, normal duty and the documented peak sequence. Use those same scenarios in acceptance planning. If production scheduling changes the coincidence of demand, revisit the sizing assumptions before adding equipment.

Apply this guidance with the equipment manual, actual site conditions and applicable requirements. Design, operation and maintenance decisions need appropriately qualified personnel. Confirmed product documents govern a specific equipment supply.
