ABSTRACT
A Coriolis flowmeter consists of two primary components: the flow tube assembly, which is typically called the sensor, and an electronics assembly. The electronics provides the energy to oscillate the flow tubes, processes the signals from the flow detectors mounted on the flow tubes, and produces outputs which represent the mass flow rate of the fluid. The electronics is comprised of three main sections: the signal interfaces between the sensor and electronics, the signal processing section, and the outputs to external devices and displays. The interfaces between the electronics and the sensor are the sensor driving mechanism, the flow detectors, and the flow tube temperature measuring device. The primary output from a Coriolis flowmeter is the mass flow rate; however, a majority of the electronics designs are also capable of providing temperature, density, and volumetric flow rate outputs.
