Measuring principle:
The Emerson Micro Motion 4200 transmitter operates on the Coriolis effect. As fluid flows through the vibrating measuring tubes inside the sensor, Coriolis force induces tube twisting, and the magnitude of this torsion is directly proportional to the fluid mass flow rate. Variations in vibration frequency correlate with fluid density. The transmitter precisely captures these signals and processes them via proprietary core algorithms to simultaneously deliver mass flow, volumetric flow, density and other process measurements. A standout feature of the Model 4200 is its two-wire loop-powered architecture, whereby both power supply and process signals are transmitted over a single pair of cables. This design drastically simplifies wiring layouts and cuts installation expenses, making the unit an optimal solution for sites with limited power availability or challenging cable routing conditions.
Product positioning:
Using scenario:
The Emerson Micro Motion 4200 two-wire transmitter is ideally suited for installations constrained by limited power budgets or high cabling costs, including legacy plant retrofits, remote field deployment and integration within skid-mounted process packages. It provides seamless interchangeability with conventional two-wire flow meters and serves a broad spectrum of industries such as chemicals, petrochemicals, refineries, oil & gas, food & beverage, and pharmaceuticals. Typical applications include continuous process control, mass balance accounting, batch control, flare gas allocation metering, and stable operation in high-pressure hydrogen service up to 700 bar. The standard Smart Meter Verification functionality conducts meter health diagnostics without process shutdown, safeguarding measurement integrity throughout operation.
