While siphon flows are thought to be common in coronal loops, detection in coronal emission has remained elusive. The Tuneable X-Ray Imager (TXI) sounding rocket will produce images of the corona in 4 Angstroms \ passbands around prominent emission lines between 170-200 Angstroms. This new instrument can also produce velocity maps from difference images taken on either side of an emission line. We present a study of the response of the TXI to siphon flows in coronal loop models. The models show that loops with flows are significantly fainter than the equivalent static loops. In addition, contamination from nearby lines tends to mask the Doppler shift, even with an instrument of excellent imaging capacity. We will outline more detailed analysis methods that may reveal the siphon flows more clearly.
