Yes, an electromagnetic flow meter can measure bidirectional flow.
Electromagnetic flow meters measure flow based on the induced voltage generated by the movement of a conductive liquid in a magnetic field. The polarity of the induced signal changes with the flow direction, allowing the meter to distinguish between forward and reverse flow.
Key points:
1. Supports forward and reverse flow measurement
2. Provides bidirectional totalization (separate or net total, depending on configuration)
3. Maintains the same accuracy in both flow directions
4. No moving parts, so performance is unaffected by flow reversal
