During the last decades, Coriolis flowmeters have become a preferred measurement technology choice for numerous industries and applications since they measure mass flow with unmatched accuracy and repeatability. In addition, they also reliably measure a wide variety of other process parameters such as volume flow, density, temperature, concentration, and a viscosity [1, 2]. All process parameters are derived by evaluating specific Coriolis sensor signals which are generated from the physical response of the sensor to the prevailing process conditions. The main sensor components involved are the measuring tubes, the exciter, and the pickup sensors.
The sensor housing is also essential for establishing a reliable measurement, as it provides a stable and dedicated environment for the sensor components to optimally perform their measuring task. In addition, the responses of the integrated temperature sensors allow reliable determination of the thermal load distribution in the Coriolis sensor. This enables an accurate compensation of the measurement parameters in case of any temperature effects. The signals generated by the sensor components are sent to the transmitter where they are processed to derive all measurement parameters, which subsequently are passed on to the process control system via the desired communication protocol.
