ABB is offering a 74-page reference guide for selecting and applying electromagnetic flowmeters (magmeters), titled Magmeter Basics–A Technical Reference Guide. The guide covers principles of operation, construction, magnetic fields, maintenance, transmitters, installation, and calibration.

The guide discusses and tabulates liquid conductivities and covers such topics as pressure loss considerations, piping configurations, and electrode coating solutions. One section covers the pros and cons of AC versus DC magnetic field excitation in question and answer format.

Illustrations in the guide are designed to help clarify the text. The guide also contains nomograms, formulas, detailed tables, and references. One table of more than 20 pages simplifies selection of electrode and liner materials for specific chemicals.
