Two-wire Electromagnetic Flowmeter
Endress+Hauser releases the Proline Promag 200 electromagnetic flowmeter, a two-wire magmeter that offers the same measuring performance as four-wire magmeters. The Promag H200 is available in line sizes of 1/12 to 1 inch and Promag P200 is available in line sizes of 1/2 to 8 inch for measuring the flow rates of conductive fluids with an accuracy of ±0.5% of range and repeatability of ±0.2 % of range. The flowmeter operates in process temperatures from -40 to 304 F. Connections include welded, threaded, hygienic and flanged versions that meet EN/DIN PN 16-40, ASME B16.5 Cl 150, Cl 300 and JIS 10K and 20K process connection pressure ratings. Installation is simpler and less costly than a four-wire device because a separate power source isn’t required. Because the meter is intrinsically safe, no seals or external enclosures are required for installations in hazardous areas. The Promag 200 has ATEX, IECEx and cCSAus approvals for installations in Class I, Division 1 and 2 groups, and for Zones 1 and 2. The Promag 200 also meets IEC 61508 SIL, ANSI and NAMUR safety requirements.
