摘要： 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.

摘要： A Coriolis flow sensor includes a metal flow tube and an enclosure. The enclosure encloses the flow tube and is constructed at least partially from a gamma transparent material. The metal flow tube may be constructed from stainless steel. The gamma transparent material and the flow tube are thin enough to permit sterilization of an interior of the flow tube by gamma irradiation of the flow tube through the gamma transparent material. The enclosure is also shaped to facilitate locking and unlocking the Coriolis flow sensor in place on a mounting structure.

摘要： Embodiments relate to a flow process system comprising a cradle and a locking mechanism. The cradle has a mounting structure for a Coriolis flow sensor, and the cradle has significantly more mass than the Coriolis flow sensor. The locking mechanism is used to lock and unlock Coriolis flow sensors in place on the mounting structure. The locking mechanism produces sufficient locking force when locked that the Coriolis flow sensor and cradle vibrate as a unitary body. In this way, the Coriolis flow sensor has effectively more mass when used as part of the flow process system, but Coriolis flow sensors may be easily replaced by unlocking the locking mechanism, removing the current Coriolis flow sensor and replacing it with another.

摘要： A flow measurement system includes two or more flow sensors that may operate simultaneously and a plurality of connected flow paths for flow of fluids. Each flow sensor is positioned along a different flow path of the plurality of connected flow paths and includes at least one flow tube and a support that clamps the flow tube. The flow tube of each flow sensor has a different resonant frequency so that cross-talk between the flow sensors can be reduced or eliminated. In some embodiments, the flow tube of each flow sensor has a different tube length, wall thickness, material, and/or weight. The flow measurement system can also include one or more pumps for pumping fluid into the flow sensors and a dampener arranged between a pump and a corresponding flow sensor for mitigating interference on the flow sensor from operation of the pump.
