Product DescriptionProduct DescriptionRosemount 2700R Micro-Motion Mass Flow TransmitterTo fully understand the capabilities of the Rosemount 2700R, it is essential to first grasp the fundamental principle behind Coriolis mass flow measurement. The Coriolis effect, named after the French mathematician Gaspard-Gustave de Coriolis, refers to the apparent deflection of a moving object relative to a rotating reference frame. In the context of flow measurement, this effect is harnessed to directly measure the mass flow rate of a fluid.The Rosemount 2700R, as a Coriolis mass flow transmitter, works in conjunction with a Micro-Motion Coriolis flow sensor. The sensor typically consists of one or two vibrating tubes through which the fluid flows. When the tubes are set into vibration (usually by an electromagnetic driver), the fluid passing through the tubes exerts a Coriolis force on the tube walls. This force causes a phase shift in the vibration of the tubes: the inlet side of the tube lags behind the outlet side, and the magnitude of this phase shift is directly proportional to the mass flow rate of the fluid.Two electromagnetic pickups (sensors) mounted on the inlet and outlet sides of the tubes detect the vibration and the phase difference between the two points. The Rosemount 2700R transmitter processes the signals from these pickups, converting the phase shift into an accurate mass flow measurement. Additionally, the transmitter can measure the frequency of the tube vibration, which is related to the density of the fluid, and use a built-in temperature sensor to monitor the fluid temperature. This multi-variable measurement capability (mass flow, density, temperature) is one of the key advantages of the Coriolis technology employed by the Rosemount 2700R, eliminating the need for separate sensors and reducing complexity in the measurement system.1. Core Features of Rosemount 2700R1.1 High Measurement Accuracy and RepeatabilityAccuracy is the cornerstone of any flow measurement device, and the Rosemount 2700R excels in this regard. It offers industry-leading mass flow accuracy, typically within ±0.15% of the measured value for liquid applications and ±0.35% for gas applications, ensuring precise monitoring and control of fluid flows. Moreover, the transmitter maintains high repeatability (as low as ±0.05% for liquids), which is essential for consistent process performance and quality control. The accuracy of the Rosemount 2700R is not affected by changes in fluid properties such as viscosity, density, or temperature, as it directly measures mass flow, eliminating the need for corrections that can introduce errors in other flow measurement technologies (e.g., differential pressure or ultrasonic flow meters).1.2 Multi-Variable Measurement CapabilityAs mentioned earlier, the Rosemount 2700R provides simultaneous measurement of three key process variables: mass flow, density, and temperature. This multi-variable functionality offers significant benefits to users. For example, in chemical processing, knowing the density of a fluid can help determine its composition, ensuring that the correct mixture of ingredients is maintained. In oil and gas applications, density measurement is critical for calculating the net standard volume (NSV) of hydrocarbons, which is essential for custody transfer operations. 1.3 Robust Construction for Harsh EnvironmentsIndustrial processes often involve harsh operating conditions, including extreme temperatures, high pressures, corrosive fluids, and excessive vibration. The Rosemount 2700R is designed to withstand these challenges, ensuring long-term reliability and performance. The transmitter's enclosure is constructed from high-quality materials such as aluminum or stainless steel, with protection ratings up to NEMA 4X (IP66/IP67), making it suitable for both indoor and outdoor installations, including hazardous areas. For applications involving corrosive fluids, the sensor tubes are available in materials such as 316L stainless steel, Hastelloy C-276, or titanium, ensuring compatibility with a wide range of chemicals. 2.
