An apparatus for measuring flow of a process fluid includes an elongate spool providing a spool conduit therethrough adapted to be coupled in line with process piping to receive the flow of process fluid. A meter body is carried by the elongate spool and receives the spool conduit therethrough. The meter body includes a flow measurement component opening which extends from the spool conduit to outside of the meter body. A flow component is configured for placement in the flow measurement component opening of the meter body. A carrier is configured to removably mount to the meter body and couple the flow measurement component to the spool conduit through the flow measurement component opening. A flow measurement transmitter couples to the flow measurement component to measure the flow of process fluid based upon an interaction between the process fluid and the flow measurement component.
