Features of MVM-250-PN Magnetic Flow Meter
- Makes liquid flows visible by
- Frequency output
- Blinking LED (red/green)
- No mechanical wear
- No moving parts
- Ease of mounting and operation
- Mounting in any position
- Free pipe cross section
- No additional pressure drop
- Fast response (<500 ms)
- Insensitive with contaminated liquids
- Ideal solution for interference free operation combined with a long-life cycle

Applications
The fields of application for this magnetic flow meter are diverse:
- Can be used in areas where flow sensors with moving parts (paddle wheel, turbine sensors) cannot be applied due to contaminated media
- Sensor is intended for continuously measuring of flow rates or for dosing / batching of electrically conductive liquids with a minimum of 50µS/cm
- Water distribution
- Chemical feed
