E-Series Advanced Diagnostics
Improve plant performance
Rosemount E-Series Advanced Diagnostics provide more instrument and process information than any other magnetic flowmeter on the market. This information then enables better decision making and plant management.
This suite of Diagnostics enables you to improve your practices by providing you with a comprehensive package of instrument and process information. The Advanced Diagnostic process information will help to reduce commissioning time, improve process control, and improve the long term reliability of your flow measurements. Advanced Diagnostic instrument information reduces maintenance costs by providing troubleshooting capabilities that are easily accessible with a HART communicator or AMS® Suite: Intelligent Device Manager.
- The ground and wiring fault detection diagnostic allows you to quickly verify that your installation is correct.
- E-Series high process noise detection diagnoses the cause of a noisy flow measurement and provides a means to remove the variability.
- With the Emerson meter verification diagnostic you can confirm the health of the entire flowmeter – transmitter and sensor – without any external equipment. In addition, it’s no longer necessary to remove the sensor from the process line, which saves time and money.

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 Material |
Application Notes |
| 316L SST |
Standard electrode material. Compatible with most low concentration water based applications. Avoid using stainless in higher concentration acid applications. |
| Nickel Alloy 276 |
Use 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. |
| Tantalum |
Ideal for high concentration acid flows such as hydrochloric and hydrofluoric acids. |
| Titanium |
Ideal for high concentration caustic (base) applications such as sodium and potassium hydroxides. | Step 4: Transmitter Selection
