Peak demand is the maximum flow rate that an installation may require at a specific moment in time. It is a critical metric for the proper selection of meters, regulators, and piping.
How it is created
It can occur when multiple burners start simultaneously or when a large consumer ramps up quickly to a high load.
Why the average is not enough
Average daily consumption may be low, but the network must be able to meet the maximum instantaneous demand.
Consequences of an inadequate network
Pressure drops, low pressure trips, and an inability for consumers to perform at full capacity may occur.
Recording
Flow and pressure trends are the best way to identify actual consumption peaks.
