ABB Offers Reference for Selecting Magmeter Liners and Electrodes
Share:
Twenty-nine page technical reference guide from ABB provides comprehensive information and data for selecting magmeter liners, electrodes, and grounding rings. The guide introduces the topic by discussing the construction of electromagetic flowmeters. It explains how magmeter durability depends on selection of proper materials for a given application. Factors governing selection are the chemicals being measured, as well as their temperature, abrasive characteristics, and sanitary requirements.
The guide continues with a discussion of cleaning materials that could affect the integrity of liners and electrodes. It notes that steam cleaning should be limited to 300°F (149°C) for meters lined with Teflon®, and meters with ceramic bodies. Polyurethane or rubber lined meters should not be exposed to steam cleaning. Other adverse effects of steam cleaning include sudden temperature changes such as rapid cooling.
The guide next covers the liner and gasket materials available from ABB, such as hard and soft rubber, PTFE, PFA, ETFE, ceramic carbide, polypropylene, and elastomers. Also discussed are issues concerning raised face and flat face pipe flanges.
The reference guide concludes with more than 20 pages of tables indicating the suitability of various liners and electrode materials for specific chemicals. Also provided are electrode corrosion rates for these chemicals as well as temperature limits.
