Rosemount Magnetic Flow Meter Liner and Electrode Selection Guide for Oil & Gas Applications Manuals & Guides
Rosemount™ Magnetic Flow
Meter Liner and Electrode
Selection Guide for Oil & Gas
Applications
Because the Rosemount Magnetic Flow Meters are designed without any protrusions or
obstructions in the pipe, they can accommodate an array of fracking, produced water, water
management and water injection applications in the oil exploration and production industry.
Specialized liner materials and electrode types can be selected for chemical, corrosion and abrasion
resistance. Below is a selection guide for common applications with specific model options and
specifications.

Very good liner material and more cost eective than PFA. Ideal for
produced water, water with hydrocarbon content at pressures below
1000 psig. For pressures above 1000 psig, consider polyurethane,
Adiprene®, or neoprene. Consult the product data sheet for pressure
and temperature de-rating chart. For applications where vacuum may
be present, consider PFA+
Very good liner material with similar properties to PTFE. Slightly better
abrasion resistance. Can be used for produced water, water with
hydrocarbon content at pressures below 1000 psig. For pressures
above 1000 psig, consider polyurethane, Adiprene, or neoprene.
Consult the product data sheet for pressure and
temperature de-rating chart.
Excellent liner for abrasion resistance to slurries with small
particles. Limited chemical and hydrocarbon resistance. Used on
clean water and high pressure applications. Recommended liner for
hydraulic fracturing blending where chemicals and acids are not being
used. For applications with high salinity, consider PTFE or PFA+ for
low pressure applications and Adiprene or neoprene for high pressure
applications.
Best liner material for abrasion resistance with excellent oil and
solvent resistance for produced water with high hydrocarbon content.
Preferred liner for high pressure produced water or water injection
applications. For applications with high sulde content (H2S) consider
PTFE, PFA+, or neoprene
Used in water with chemicals and seawater/saltwater applications.
Limited hydrocarbon resistance. Good application for produced
water with low hydrocarbon content and high pressure water injection.
If application contains aromatic hydrocarbons such as benzene or
toluene, consider using PTFE, PFA+, or Adiprene

Application Consideration
The most common electrode material used. It has reasonable corrosion resistance and adequate abrasion resistance
for most applications. Stainless is a no charge adder. Not recommended for sulfuric or hydrochloric acids or produced
water with high salt content.
Oers improved corrosion resistance compared to stainless steel, especially in lower concentration acid applications
and salt water. It also oers better abrasion resistance, particularly in applications where there is a high concentration
of solids particles. Nickel Alloy is the same price as SST and is an excellent choice in most O&G applications.
Most expensive electrode material oered and the most versatile. Typically, not needed in most O&G applications. Good Best P
Suited for high caustic concentration uids and oers poor chemical resistance to acid applications. Because it is
a very hard material, it oers superior abrasion resistance to slurries and uids with particles present in the ow stream.
Special electrode material, available with a at electrode head (T), suited for the most abrasive applications. Recom-
mended electrode for hydraulic fracturing blending applications due to high sand / proppant content.
Special electrode material, available with a at electrode head (T), suited for the most abrasive applications. The Nickel
Alloy base material is recommended for hydraulic fracturing blending applications where higher concentrations of
acids or chemicals are being injected with the fracturing uid.
Abrasion
Resistance
Lowest cost electrode that is good for most applications. In applications where coating is an issue, the
ow meter should be sized to keep the velocity above 3 ft/s to minimize electrode coating potential.
Slightly more expensive, but best option for coating applications. Electrode extends further into the ow
stream providing a natural cleaning eect in processes susceptible to coating such as produced water
with oil content. For applications where abrasion may occur, or applications with solid content such as
sand, consider using a standard or at head electrode.
This electrode option is intended for highly abrasive applications. The at head and ush mount design
provides added protection for the electrode from impingement of the abrasive media. For applications
where coating is a concern, consider using bullet nose electrodes.
