Electromagnetic Flow Meter
Brand: Sur-Flo Meters & Controls LtdThe Sur-Flo Meter M-Series® SM2000 is the result of years of research and field use of electromagnetic flow meter technology.
Based on Faraday’s law of induction, these meters can measure almost any liquid, slurry or paste that has minimum electrical conductivity.
Designed, developed and manufactured under strict quality standards, the M-Series meter features sophisticated, processor-based signal conversion with accuracies of ±0.25 percent.
The wide selection of liner and electrode materials helps ensure maximum compatibility and minimum maintenance over a long operating period.
Features- Available in sizes 0.25…54" (6…1350 mm)
- Pulsed DC magnetic field for zero point stability
- Integral and remote signal converter availability
- Corrosion resistant liners for long life
- Measurement largely independent of flow profile
- User friendly programming procedure
- Empty pipe detection
- Power loss totalization
- Digital signal processor (32-bit)
- Non-volatile programming memory
- Rotating cover
- Calibrated in state-of-the-art facilities
- NSF listed
- CSA certified
