Product Description

Product Description

Rosemounte F300

In the intricate web of industrial processes, precise measurement of mass flow is of paramount importance. From ensuring accurate dosing in chemical reactions to optimizing fuel consumption in power generation plants, the ability to measure mass flow accurately and reliably can significantly impact the efficiency, productivity, and profitability of industrial operations. The Rosemounte F300DN80 Mass Flowmeter, a product of Emerson's renowned engineering prowess, has emerged as a leading solution in this critical area of industrial instrumentation.
Engineered with precision and designed to meet the diverse and demanding requirements of various industries, the F300DN80 combines advanced technology with rugged construction. It offers high - performance mass flow measurement capabilities, making it an ideal choice for applications where accuracy, reliability, and long - term stability are non - negotiable. With the ever - increasing need for enhanced process control, improved product quality, and reduced operational costs in modern industrial settings, the Rosemounte F300DN80 plays a pivotal role. It provides real - time, accurate mass flow data, enabling operators to make informed decisions, optimize processes, and ensure the seamless operation of industrial plants. Whether it is in a large - scale petrochemical complex, a food and beverage manufacturing facility, or a pharmaceutical production line, the F300DN80 has proven its mettle in delivering consistent and reliable mass flow measurement results.

 1. Working Principle

1.1 Coriolis Effect - The Heart of the Measurement
The Rosemounte F300DN80 Mass Flowmeter operates based on the Coriolis effect, a well - established physical principle. At its core, the flowmeter consists of a vibrating measuring tube or tubes through which the fluid (liquid or gas) whose mass flow is to be measured passes. When a fluid flows through a vibrating tube, the Coriolis force acts upon it.
The measuring tube is excited to vibrate at a specific natural frequency. As the fluid enters the vibrating tube, the Coriolis force causes a phase shift in the vibration of the tube. The magnitude of this phase shift is directly proportional to the mass flow rate of the fluid. To better understand this, consider a simple analogy of a person spinning on a rotating platform while trying to walk straight across it. The person will experience a force that deflects their path, which is similar to the Coriolis force acting on the fluid in the vibrating tube.
Mathematically, the mass flow rate m can be calculated from the measured phase shift Δφ. The relationship is given by m=K×Δφ, where K is a calibration constant specific to the particular F300DN80 flowmeter. This calibration constant takes into account factors such as the geometry of the measuring tube, the material properties of the tube, and the characteristics of the excitation system.
1.2 Density Measurement as an Added Benefit
In addition to measuring mass flow rate, the F300DN80 can also accurately determine the density of the fluid flowing through it. The density measurement is derived from the natural frequency of the vibrating tube. The natural frequency of the vibrating tube changes with the density of the fluid inside it. A denser fluid will cause the tube to vibrate at a lower frequency compared to a less dense fluid.
1.3 Temperature Compensation for Precision
The performance of the Coriolis - based mass flowmeter can be affected by temperature variations. The dimensions of the measuring tube can change with temperature, which in turn can impact the natural frequency of vibration and the phase shift measurements. To account for these temperature - induced effects and ensure accurate mass flow and density measurements, the Rosemounte F300DN80 is equipped with an integral temperature sensor

2. Product Features

2.1 Exceptionally High Accuracy
The Rosemounte F300DN80 is engineered to deliver outstanding measurement accuracy. With a typical accuracy of ±0.1% of the measured mass flow rate, it sets a high standard in the industry. This level of precision is crucial in applications where even the slightest deviation in mass flow measurement can have significant consequences.
In the pharmaceutical industry, for instance, accurate mass flow measurement of raw materials and ingredients is essential for ensuring the consistent quality of drugs. A small error in the mass flow rate during the manufacturing process could lead to variations in the dosage of active ingredients, which could potentially affect the efficacy and safety of the final product. In the aerospace industry, where fuel consumption needs to be precisely monitored for performance optimization and safety reasons, the high accuracy of the F300DN80 is invaluable.
2.2 Wide Flow Range Capability
The F300DN80 is designed to cover a wide flow range, making it suitable for a diverse range of applications. It can accurately measure mass flow rates from very low flow values up to relatively high flow rates. This wide flow range flexibility is a significant advantage as it reduces the need for multiple flowmeters with different flow range capabilities in a single industrial plant.
For example, in a water treatment plant, the F300DN80 can be used to measure the flow of chemicals used in the treatment process, which may have a relatively low flow rate, as well as the flow of treated water being discharged, which could have a much higher flow rate. In a refinery, it can handle the mass flow measurement of various process fluids, from the low - flow catalysts to the high - flow crude oil and refined products. 
2.3 Low Pressure Drop
One of the key features of the Rosemounte F300DN80 is its low pressure drop design. Pressure drop is the difference in pressure between the inlet and outlet of a flowmeter, and excessive pressure drop can cause energy losses and operational inefficiencies in a fluid system. The F300DN80 is engineered to minimize this pressure drop, ensuring that the flow of the fluid is not significantly impeded.
