Abstract: A system of one or more configurable flowmeters allows an individual, locally or remotely, to selectively activate one or more functions of the flowmeters. The individual is capable of selecting which parameter of the process flow that the flowmeter is to measure, thereby effectively providing latent functions that may be selectively brought on line or shut off. The system may also allow an individual, locally or remotely, to selectively activate one or more latent flowmeters in the system. The system may be a distributed control system (DCS), which receives input signals from conventional meters and devices in the process flow and provides control signals to one or more devices in the flow process. The system may also provide a method of flowmeter selection and billing.

Abstract: A quartz sensing system includes a quartz sensor, an electromechanical converter, an optical source, an optical fiber and a signal processor. The quartz sensor responds to a pressure, and further responds to an electrical power signal, for providing a quartz sensor electrical signal containing information about the pressure. The electromechanical converter responds to the quartz sensor signal, for providing an electromechanical converter force containing information about the sensed voltage or current signal. The optical source for provides an optical source signal. The optical fiber responds to the electromechanical converter force, for changing an optical parameter or characteristic of the optical source signal depending on the change in length of the optical fiber and providing an electromechanical converter optical signal containing information about the electromechanical converter force.
