McCrometer develops innovative, high-quality, precision flow meters for the most demanding liquid, steam and gas measurement industry applications for its worldwide customers.

  Mag Flow Meters  

McCrometer’s Ultra Mag®, FPI Mag® and SPI™ Mag (Single Point Insertion) Flow Meters are designed for use in municipal water environments. They operate over a wide flow range with no moving parts to wear.

The Ultra Mag® — The 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.

Key Features / Benefits:

  • Ultra Mag Non-invasive sensing (non-clogging) flow element
  • Superior durability with fusion-bonded epoxy Ultraliner (certified by NSF)
  • Custom-built to fit your application (special lay lengths and flanged end connections)

FPI Mag® — The FPI Mag flow meter from McCrometer installs without cutting pipe, welding flanges, de-watering lines or interrupting service; dramatically reducing installation time and costs including heavy equipment and added labor by up to 45% over traditional full pipe flow meter installation.



  • Distribution
  • Effluent
  • UV Dosing
  • Filter Balancing and Backwash
  • Wells & Booster Stations


  • Effluent
  • Recycle / Reclaim

Features & Benefits:

  • Simple Installation
  • Lower Cost
  • Unmatched Accuracy
  • Robust Construction / No Moving Parts
  • Versatile
  • Single Piece Design

SPI Mag™ — The SPI Mag Insertion Flow Meter provides a highly cost-effective solution for the accurate measurement of liquid flow in closed conduit, pressurized pipe applications. Unlike conventional magnetic meters, the SPI Mag’s cost is independent of pipe size. Velocity and pipe diameter information are utilized by the SPI Mag to determine flow over wide flow ranges with a high degree of accuracy.

The SPI Mag reliably measures flow in water and wastewater as well as any type of industrial flow processes involving conductive fluids such as potable water, slurries, sludge, cooling water, and pulp stock.


  • Supports pressurized line sizes from 2 to 96 inches (50mm - 2,440 mm)
  • Accuracy: ±2% of reading ±0.03 ft/s (± 0.009 m/s) zero stability from +0.3 to +32 ft/s (0.09 to 10 m/s) velocity range
  • Dual 4-20 mA analog outputs
  • Proven electromagnetic technology based on Faraday’s Law
  • Debris shedding, self cleaning sensor eliminates costly maintenance
  • Cost is independent of pipe size.
  • Easy installation/no interruption of flow process


  Propeller Flow Meters  

The Water Specialties Propeller Meter™ and Mc® Propeller Meter are the industry’s most popular propeller meters with 55-plus years of proven service. They set the standard for ease-of-use, reliability and economy.

Water Specialties Propeller Meter™ — The Water Specialties Propeller Meter is the best choice for measuring clean water flows in municipal and industrial applications. The meter is engineered to deliver superior performance, low maintenance and unsurpassed durability. Meter materials and performance meet or exceed AWWA standard C704/92.

Measurement accuracy is +/- 2% of reading. The meter accommodates flow ranges from 35 GPM to 200,000 GPM. The Water Specialties Propeller Meter can be installed vertically, horizontally or inclined, with sizes ranging from 2" to 120".


  • Proven design for clean water flows
  • Quality construction
  • Long-life components
  • Meets/exceeds AWWA standard
  • Accuracy of +/-2% of reading
  • Wide flow range

Mc® Propeller Meter — McCrometer has set the standard for liquid flow measurement performance, ease-of-use and value in the agricultural and turf markets since 1955. Its leading-edge propeller flow meters offer economical and versatile flow measurement. The Mc Propeller is especially suited to dirty water flows, municipal and other high-volume water applications.

There are no tight tolerances in the Mc Propeller. It handles solids suspended in water without clogging. With its high accuracy, this flow meter is also a water management tool, helping to reduce water costs, preventing over-irrigation and reducing leaching of chemicals and fertilizers into the ground.


  • Best-selling irrigation meter in the US
  • Clean and dirty flows
  • Easy to install and operate
  • Easy to service in the field
  • Accuracy of +/-2% of reading
  • Repeatability of +/-0.25%
  • Self-cleaning design
  • Instantaneous flow rate Indicator-totalizer on every model
  • Turndown: up to 15:1
  VM V-Cone System™  

The VM V-Cone System's self-conditioning advanced differential pressure flow meter offers accurate liquid flow measurement with little to no straight pipe run requirements. The VM V-Cone System is the ideal flow meter for reducing footprint and simplifying pipe layout in new installations and fitting in space constrained retro-fit applications.

Features & Benefits:

  • System accuracy of ±0.5% of rate

  • Flow range: 10:1

  • Installation: Typically 0-3 diameters upstream and 0-1 diameter downstream

  • No parts to wear so little maintenance required

  • HART® and Digital Protocols

  • Totalizer pulse and linear 4-20mA outputs

  • 3-way manifold for isolating the transmitter

  • Displays both rate of flow and total flow

  • Rate and total functions are independent of each other allowing for many different combinations of flow units
