1. A system to determine a time-of-flight in an integrated flow meter, comprising:
a housing comprising an inlet port and an outlet port;
a plurality of flow tubes connected in parallel to each other, wherein each flow tube among the plurality of flow tubes includes at least two transducers that measure upstream and downstream time-of-flight, wherein each flow tube further includes:
at least one outlet of each flow tube connected to the outlet port of the housing via an outlet channel; and
a controller connected to the at least two transducers of each flow tube, wherein the controller is operable to:
measure a time-of-flight in a flow tube among the plurality of flow tubes for a predetermined time using the at least two transducers,
toggle between the at least two transducers of each flow tube to measure the remaining flow tubes among the plurality of flow tubes within the predetermined time, and
determine an overall flow rate of the plurality of flow tubes in the integrated flow meter.
