Low-Power, High-Integration Two-Wire Electromagnetic Flowmeter
A two-wire electromagnetic flowmeter refers to an electromagnetic flowmeter that simultaneously accomplishes power supply and signal transmission using only two wires.
| Characteristics | Two-wire Electromagnetic Flowmeters | Four-wire Electromagnetic Flowmeters |
|---|---|---|
| Wiring | Two wires (power + signal) | Four wires (two power wires + two signal wires) |
| Power Supply | Loop-powered, DC 24V (commonly used) | Independent power supply, AC 220V or DC 24V |
| Power Consumption | Extremely low (must be ≤ 3.6mA @ 24V, i.e., ≤ 86.4mW) | High, unrestricted, can drive stronger excitation. |
| Maximum Distance | Limited by loop voltage drop, usually at the kilometer level. | Unrestricted power supply distance, signal transmission distance the same as two-wire. |
| Intrinsic Safety | Easy to achieve, preferred in hazardous areas. | More complex to achieve, usually flameproof (Ex d). |
| Cost | Low wiring cost, the meter itself may be slightly more expensive. | High wiring cost, the meter may be cheaper. |
| Applicable Scenarios | High explosion-proof requirements, scattered points, long distances, new digital factories. | Non-explosion-proof areas, on-site power supply available, occasions with extremely high requirements for response speed/functions. |
Two-wire electromagnetic flowmeters are a successful example of the development of electromagnetic flowmeter technology towards "low power consumption, high integration, and intrinsic safety". It is not merely a change in wiring method, but also an innovation in system design concept.
