Chemical plants and refineries around the globe are dealing with unreliable legacy 2-wire flow points and are looking for the upgrade migration path to a more accurate and reliable measurement. Traditionally, Coriolis meters have not been thought of as part of the 2-wire upgrade revolution as the option didn’t exist.
With the release of the new Micro Motion 4200 2-wire Coriolis transmitter Emerson now makes the upgrade migration to Coriolis possible. The 2-wire Coriolis transmitter improves reliability by providing a repeatably accurate mass flow and density measurement, optimizes production, ensures safety by producing accurate fills resulting in less exposure and spill hazards from overfilling, and eliminates cost by reducing engineering and planning time.
Retrofit Transmitter Challenges
The challenges for most chemical and refinery operations of retrofitting existing 2-wire flow points include upgrading without installing additional wire, plant expansions where power is not centrally located, and the need to install back up power on critical flow point devices. The 2-wire Coriolis transmitter eliminates cost by using the existing wiring and without the need to run additional wiring, scaffolding, conduit, AC panels, and transformers. With this solution, the complexity, length of time, and cost for the project is reduced significantly.
In many cases it becomes a matter of swapping out the existing – legacy – meter for a the 4200 2-wire Coriolis transmitter.
Flow Meter Diagnostics
The Micro Motion 2-wire Coriolis transmitter provides a reliable, accurate mass flow and density measurement along with standard meter health diagnostics, such as Smart Meter Verification, to provide confidence in the meter performance. The transmitter also provides a data historian with real-time clock to help you make sense of meter health reports, process data, and includes a complete audit trail.
Audit trails that can be used to meet compliance requirements and compile statistical data on meter operations and plot your flow over time.
Benefits of Upgrading to a 2-Wire Transmitter
Some of the benefits of upgrading to the 4200 2-wire Coriolis transmitter that can be realized is the elimination or reduction of costs for detailed engineering, installation labor, wiring, conduit, AC panels, transformers and planning since the Micro Motion 2-wire Coriolis transmitter shares power and signal over the same pair of wires and can easily accommodate retrofitting legacy 2-wire flow points and in plant expansions where power is not centrally located.
Below we’ve broken out a hypothetical plant upgrade with CAPEX estimate.
Most of the savings when selecting 2-wire Coriolis transmitter will be in the design package for the project. Let’s breakdown the numbers for a simple installation with AC power within 150’ of a new meter:
Let’s run the numbers on an AC Power Panel 500’ away:
