1. A flow meter comprising:
a detector that transmits a signal to a fluid and receives a signal from the fluid;
a memory configured to store instructions; and
a processor electrically connected to the memory and configured to execute the instructions,
wherein,
when the instructions are executed by the processor, the processor is configured to
calculate a first flow-rate value of the fluid using a signal transmitted to the fluid and a signal transmitted from the fluid, determine whether the first flow-rate value is missing, calculate a second flow-rate value of the fluid using a physical quantity of the fluid if the first flow-rate value is missing, and replace the missing value with the second flow value,
wherein
the physical quantity is configured to
be measured by an auxiliary sensor installed on a pipe through which the fluid flows.
