Flowmeter Primer: Two-Wire Coriolis and Electromagnetic Transmitters

Two-wire transmitter technology came about from an agreement among various instrument suppliers in the 1950s to standardize on 4–20 mA current loops as a means of sending a flow, temperature, pressure, or similar process signal back to control and monitoring systems. In the 1980s, HART was added to the 4–20 mA signal, providing additional calibration […]
