Product Description

Product Description

The Rosemount 8711 Electromagnetic Flowmeter, developed by Emerson, a renowned leader in industrial automation and measurement solutions, is a cutting - edge device engineered to meet the diverse and demanding needs of modern fluid measurement applications. This flowmeter is designed to provide highly accurate, reliable, and repeatable flow rate measurements of conductive fluids, making it an indispensable asset across a wide range of industries.

 

Exceptional Accuracy:

At the heart of the Rosemount 8711 lies the principle of electromagnetic induction. When a conductive fluid flows through the measuring tube of the flowmeter, which is surrounded by a magnetic field generated by the meter's coils, an electromotive force (EMF) is induced. According to Faraday's law of electromagnetic induction, the magnitude of this induced EMF is directly proportional to the velocity of the fluid flow, the strength of the magnetic field, and the diameter of the measuring tube. The flowmeter's sensors detect this induced EMF and convert it into an electrical signal. This signal is then processed by the meter's internal electronics, which calculate and output the flow rate of the fluid in various engineering units, such as gallons per minute, cubic meters per hour, or liters per second.

 

Wide Rangeability:
The 8711 is equipped with optimized sensor technology that can effectively capture large flow fluctuations commonly encountered in oil and gas production applications. This ensures accurate flow rate calculations, even in challenging conditions. For example, in a well with fluctuating flow rates due to reservoir characteristics, the transmitter can precisely measure the changes and provide reliable data for production management.

Robust Construction for Harsh Environments:
The Rosemount 8711 offers outstanding measurement accuracy, typically achieving an accuracy of ±0.2% of the flow rate. This high level of precision ensures that the measured flow values closely match the actual flow rates, even in applications where small inaccuracies can lead to significant errors in process control, inventory management, or billing. For example, in chemical manufacturing processes where precise fluid dosing is crucial for product quality, the 8711 provides reliable and accurate flow measurements.
