A flow tube (10) has a housing (12, 14) including at least a first housing half (12) and a second housing half (14). Each housing half (12, 14) has a connection surface (20, 22) intended for combination with the other housing half (12, 14). The connection surfaces (20, 22) enclose a mounting gap (30) for an orifice element (16). Outside of the mounting gap (30) the connection surfaces (20, 22) butt against each other in some sections by respective abutting surface portions (32, 34), and outside of the mounting gap (30) and outside of the abutting surface portions (32, 34) the housing halves (12, 14) are integrally combined with each other. A method is provided for producing the flow tube, namely for integrally joining the housing halves (12, 14).
