McCROMETER Ultra Mag Electromagnetic Flow Meter


A New Standard for Performance

 McCROMETER Ultra Mag Electromagnetic Flow Meter 

Ultra Mag


Electromagnetic Flanged Flow Meter with Minimal Straight-run Requirements

The Ultra Mag is an advanced, leading-edge magmeter that requires only 1D upstream and 0D downstream of most flow disturbers, and still maintains 0.5% accuracy across a large flow range. The field-proven electromagnetic flow meter was designed for the specific needs of the industrial and water & wastewater industries. The mag flow meter's unique NSF-approved UltraLiner™ provides superior electrical insulation as well as excellent protection against corrosion and abrasion.

Use in hazardous locations :

  • Class 1, Division 2, Groups A-D, T5
  • Class 2, Zone 2, Groups A-D, T5

  Another Article:

- Non-intrusive measurement
- NSF-approved, fusion-bonded epoxy liner: the UltraLiner
- Signal converter (can be meter mounted or remote mounted up to 500 ft. away)
- Meter is wet calibrated in NIST traceable calibration facility
- Forward and reverse flow outputs and totalization

Pipe Sizes 

  • 2" to 48”

Flow Direction Measurement

  • Forward and reverse flow indication and forward, reverse, net totalization are standard with all meters


  • Plus or minus 0.5% of actual flow (battery powered is ±1% of flow)
    IMPORTANT NOTICE ON FLOW METER ACCURACY : The flow meter, the cable and the electronics are factory calibrated for accuracy as a single unit. Changing the cable length with the Splice Kit changes the accuracy of the meter and invalidates the calibration certificate.

Accuracy Tests

  • 5-point wet flow calibration of every complete flow tube with its signal converter. If desired, the tests can be witnessed by the customer. The McCrometer test facilities are traceable to the National Institute of Standards & Technology. Uncertainty relative to flow is ±0.15%

Pipe Run Requirements

  • 2” & 3” : wafer style 3D upstream / 1D downstream
  • 2” and larger flanged : 1D upstream / 0D downstream


  • ±0.05% or ±.0008ft/s (±0.25mm/s), whichever is greater


  • 5 ┬Ás/cm


  • UltraLiner NSF approved, fusion bonded epoxy


  • Type 316 stainless steel, others optional
