Micro Motion RFT97121PNU Remote Flow Transmitter

The Micro Motion RFT97121PNU is a remote flow transmitter designed for use with Coriolis flow sensors, providing accurate measurements of mass flow, density, volume flow, and temperature. Manufactured in 1999, this unit is part of the legacy RFT9712 series, known for its robust performance in industrial applications such as chemical processing, oil and gas, and food and beverage industries. It features intrinsically safe outputs, HART communication compatibility, and hazardous area certifications (e.g., UL Class I Div 2). Key benefits include high accuracy (up to ±0.1% for mass flow), no moving parts for low maintenance, and the ability to handle multiphase fluids without recalibration. Drawbacks may include its older technology lacking modern digital interfaces like FOUNDATION Fieldbus, making it less suitable for newer integrated systems compared to current Elite or 5700 series transmitters. This model excels in remote mounting scenarios, offering reliable data transmission over long distances. Based on attached images, the unit appears used, with visible wear on the enclosure and internal circuit board, but no major damage. It includes calibration factors from February 1999, such as frequency output at 150 Hz +15 lb/min and density calibration.
