Emerson Rosemount 8712ESR1A1N0MA Flow Transmitter

Emerson Rosemount 8712ESR1A1N0MA Flow Transmitter is a 90–250 VAC powered magnetic flowmeter transmitter that converts a Rosemount magnetic flow sensor signal into a reliable 4–20 mA process variable for industrial flow control. Designed for wall- or panel-mounted installation in demanding environments, it draws about 0.45 A on AC power and typically consumes up to 40 VA, matching the Rosemount 8712 family’s power profile. Inside, it provides coil excitation up to 500 mA with a maximum of 40 V, supporting robust operation of the magnetic flow sensor it accompanies. This transmitter is compatible with Rosemount sensor families such as the 8705, 8711, and 8721, enabling seamless integration with conductive-liquid flow measurements across water and wastewater, chemical processing, and general industrial applications. The ESR1A1N0MA variant identifies a specific enclosure/installation configuration within the Rosemount 8712 portfolio, delivering a durable, field-proven solution for accurate flow signaling in process automation environments.
