McCrometer Seals the Deal on the Achilles Heel of Magnetic Flow Meters
A McCrometer Ultra Mag installed in a municipal well
Magnetic flow meters can have an Achilles heel in their design
but engineers at McCrometer have sealed the deal through
careful manufacturing techniques and the use of fusion-bonded
epoxy to prevent contamination with drinking water, wastewater
and industrial streams which the instruments are measuring. The
company received new NSF certifications for its Ultra Mag and
Dura Mag electromagnetic flow meters recently, marking further
testament to the robustness of the materials and manufacturing
process, as well as the integrity of its quality team.
" The fusion-bonded epoxy is a major component of why these
mag meters meet NSF standards, " explained Memphis Huff V,
product manager for the magmeter product line and quality lead
for McCrometer. " It has a lifetime guarantee that the epoxy will
prevent liquid from reaching non-stainless components, rubber
seals, polyurethane, and more in the meter body. The mag
meters' NSF certification is really due to the power of the epoxy! "
The flow meters are approved for potable water applications,
food and beverage applications, water treatment centers, and
even applications for crop irrigation or livestock watering.
Electromagnetic flow meters can be highly accurate for measuring
stream flow and are typically applied in full-bore or insertion
style devices. Called magmeters, they operate on the principle of
Faraday's Law. This principle basically states that as a conductor,
such as water, moves through a magnetic field it produces
an electrical signal. Full-bore magmeters use an electromagnet
mounted on the outside of the pipe, perpendicular to the flow

direction. As flow passes through the magnetic field, electrically
charged ions accumulate, with negative ions on one side and
positive on the other. The resulting change in voltage is directly
proportional to the velocity of the fluid passing through the pipe,
which can be converted to volume. Insertion magmeters operate
a little differently. For an insertion meter, a very small, localized
magnetic field is inserted into the pipe. Electrodes cause charge
bearers to separate. With a full-profile insertion meter, electrodes
are located along the entire cross-section of flow to measure
average velocity across the pipe centerline.
