Technical Specifications and Operating Principles
Measurement Technology
The Rosemount 8705 Flow Meter utilizes electromagnetic flow measurement technology, also known as magnetic flow metering. This technology is based on Faraday's law of electromagnetic induction, which states that a voltage is induced in a conductor moving through a magnetic field. In the case of the Rosemount 8705, the conductive liquid acts as the moving conductor. The meter creates a magnetic field across the flow tube, and as the conductive liquid passes through this field, it generates a small voltage. This voltage is directly proportional to the flow velocity of the liquid. By measuring this induced voltage and applying calibration factors, the Rosemount 8705 accurately determines the flow rate of the liquid passing through the meter.
Flow Range and Accuracy
The Rosemount 8705 Flow Meter offers an impressive flow range capability, accommodating various process requirements. It can measure flow rates from as low as 0.04 m/s (0.15 ft/s) up to 10 m/s (33 ft/s), making it suitable for both low-flow and high-flow applications. This wide range allows for accurate measurements across different operational conditions and process stages. In terms of accuracy, the Rosemount 8705 delivers exceptional performance. It typically achieves an accuracy of ±0.25% of rate for most applications, with options for even higher precision in certain configurations. This level of accuracy is crucial for processes that require precise control and monitoring of fluid flow, such as in pharmaceutical manufacturing or custody transfer applications.
