A system and method of maintaining back pressure located downstream of the Coriolis meter maintains the pressure downstream of the Coriolis meter in relation to the surface back pressure (SBP). At least one flow control device is located downstream of the Coriolis meter. The flow control device of the present invention (the BPV) automatically maintains the downstream pressure to less than or equal to fifty percent (50%) of the surface back pressure. A pressure regulator sets the back pressure to allow for a standalone device. Additional valves allow adjustment of the back pressure and allow for pressure relief and full flow bypass.

A flow sensor includes a flow tube in a form of a tube and a support cast around the flow tube. The support clamps the flow tube and the flow tube extends through the support. The flow sensor is formed by placing the flow tube in a tube cavity of a casting mold and pouring or injecting a liquid resin into a support cavity of the casting mold. The support is formed around the flow tube from solidifying the liquid resin in the support cavity of the casting mold. A temperature of the casting mold during formation of the support does not exceed a threshold temperature to avoid deformation of the flow tube. The flow sensor can also include at least one memory chip that stores calibration information associated with the flow sensor and connectors that allows a controller to read the calibration information from the memory chip.
