<p>A calibration system for a flow meter 10 includes a flow simulator 60, the flow simulator including a receiver configured to receive flow meter transducer signals from a flow meter. A simulation subsystem is configured to create simulated transit time signal pulses, and to transmit the simulated transit time signal pulses to the flow meter 10 at preselected time intervals. A calibration subsystem 20 is configured to receive from the flow meter a transit time differential value generated by the flow meter based on the simulated transit time signal pulses and output a calibration factor to the flow meter.
