McCrometer Ultra Mag Flowmeter

Ultra MagThe Ultra Mag is an advanced, leading-edge electromagnetic flow meter. The field-proven flow meter was designed for the specific needs of the industrial and water & wastewater industries. The unit’s unique NSF-approved UltraLiner™ provides superior electrical insulation as well as excellent protection against corrosion and abrasion.

The Ultra Mag sets a new standard for performance, ease-of-use and value. It is designed specifically for conductive liquids, slurries and sludge. It uses a non-intrusive measurement element. Debris / solids will not clog the line. The Ultra Mag is excellent in harsh environments requiring minimal maintenance. It’s ideal in water well production, pump stations, industrial / municipal water & wastewater and more. The UltraMag can be ordered with custom lay lengths to fit space requirements. Optional end connections include ANSI, DIN, JIS, smooth, and grooved ends.

The 4-12” meters feature a new compact design with integral grounding electrodes that eliminate the need for grounding rings.The installation is simplified and the meter is easier to handle.

Magmeters provide worry-free flow measurement where high accuracy over a wide flow range is critical. Unlike mechanical flow meters, there are no moving parts. Measurement is unaffected by changes in fluid density and viscosity. The Ultra Mag is an exceptionally stable and reliable flow meter. As always, all of McCrometer's flow meters are individually calibrated in our world-class NIST traceable calibration facilities.

Key features include:
  • Fusion-bonded NSF approved epoxy UltraLiner / Durable, submersible, abrasion / corrosion resistant
  • Coil sweeps wide pipe cross section / Accurate across wide flow range
  • Accuracy: +/-0.5% of actual flow / Reliable meter that never requires recalibration
  • Customized lengths and flanges / Reduces installation costs
  • Compact Design / Easier to install
  • Low Maintenance / Non-intrusive sensing element, debris / solids will not clog the line
Click to openHow It Works:
  • Ultra MagAs fluid passes through the pipe, a voltage directly proportional to the flow rate is generated.
  • This voltage is measured by electrodes inserted through the flow meter lining.
  • The reading is then converted to give rate of flow and total flow measurements.
