Why Choose the 8732E Electromagnetic Flow Meter?
The 8732E magnetic flow meter uses electromagnetic flow measurement technology to provide dependable measurement of conductive liquids. Unlike many mechanical flow measurement technologies, a magnetic flow meter has no moving components in the flow path.
This makes electromagnetic flow measurement particularly useful for industrial processes where low maintenance, reliable operation, and long service life are important.
Remote Display with 10-Meter Cable
The remote display configuration provides greater installation flexibility. The flow sensor can be installed directly on the process pipeline while the transmitter/display is positioned up to 10 meters away at a more convenient and accessible location.
This arrangement can be particularly useful where the pipeline is difficult to access or the display needs to be located in a safer or more convenient operating position.
4–20 mA and Pulse Output
The Rosemount 8732E flow meter supports commonly used industrial output signals, including:
- 4–20 mA output for continuous flow measurement
- Pulse output for flow totalization and monitoring
- HART communication for configuration, diagnostics, and integration with compatible control and instrumentation systems
These communication options make the 8732E suitable for integration with PLC, DCS, SCADA, flow totalizers, indicators, and industrial automation systems.
Working Principle of an Electromagnetic Flow Meter
A magnetic flow meter operates according to the principle of electromagnetic induction.
When an electrically conductive liquid moves through the magnetic field generated by the flow meter, a voltage is induced. The measured voltage is related to the velocity of the liquid. Using the known internal diameter of the flow tube, the transmitter calculates the volumetric flow rate.
Because the measurement does not depend on mechanical moving parts, electromagnetic flow meters are widely used for continuous industrial liquid flow measurement.
