Rosemount E-Series Magnetic Flowmeter Transmitters 

Technology that Makes a Difference

The Rosemount E-Series Magnetic Flowmeter Transmitters have multiple diagnostics available. Best-in-Class performance coupled with advanced diagnostics provide unparalleled process management capabilities. With an optional backlit Local Operator Interface (LOI), configuration changes and adjustments can be accomplished even in hazardous locations without exposing the electronics to the environment.

Advanced diagnostics give unparalleled information about process conditions and meter performance.

Dual compartment housing design that meets the most stringent international standards and ensures reliability in any environment.

Isolated Local Operator Interface (LOI) makes changes in the field safe and easy.

Available in an integral or remote mount design.

15 - 350 mm
0.5 - 14 inch
Wafer
4 - 8 mm
0.15 - 0.3 inch
PTFEBETTER FLUOROPOLYMER
More cost effective than PFA. Excellent chemical resistance, but less abrasion resistance than PFA.

0.5 - 36 inch
Wafer
15 - 200 mm
0.5 - 8 inch
ETFEGOOD FLUOROPOLYMER

 LinatexTypically applied to mining slurries, abrasion resistant to larger debris.0 to 158°F (-18 to 70°C)Flanged
80 - 900 mm
1.5 - 36 inch

Step 3: Electrode Type and Material Selection
 Electrode Type Application Notes 
Button Standard electrode design. Use for most applications, especially where abrasion is a concern. Has fair resistance to coating which can be improved by properly sizing sensor. 
Bullet-nose Use where coating is a concern and no solids are present. Bullet-nose electrode should not be used in abrasive or slurry applications as the particles will result in increased process noise on the electrodes. 
Electrode MaterialApplication Notes
316L SSTStandard electrode material. Compatible with most low concentration water based applications. Avoid using stainless in higher concentration acid applications.
Nickel Alloy 276Use in medium to high concentration acids where SST is not acceptable. Use in applications with high chloride concentrations, such as sea water.
Platinum
(80% Platinum, 20% Iridium)
Ideal for liquor applications found in pulp and paper industry. Also ideal as a spare electrode option to cover nearly every application in a plant. Compatible with nearly every process fluid.
TantalumIdeal for high concentration acid flows such as hydrochloric and hydrofluoric acids.
TitaniumIdeal for high concentration caustic (base) applications such as sodium and potassium hydroxides.
