Endress and Hauser has released the Proline Promag H200 and P200 series electromagnetic flowmeters — two-wire mag meters that offer the same measuring performance as four-wire mag meters.

The Promag H200 is available in line sizes of 1/12in to 1in, while the Promag P200 is available in line sizes of 0.5in to 8in.

Installation of the Promag 200 flowmeters is said to be simpler and less costly than that of four-wire devices, because a separate power source is not required.

As the meters are intrinsically safe, no seals or external enclosures are required for installation in hazardous areas.

Key features and specifications

  • The Promag 200 flowmeters are capable of measuring the flow rates of conductive fluids with an accuracy of ±0.5 per cent of range and repeatability of ±0.2 per cent of range.
  • The flowmeters operate in process temperatures ranging from -40°F 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.
  • The Promag 200 flowmeters have Atex, IECEx and cCSAus approvals for installations in Class I, Division 1 and 2 groups, and for Zones 1 and 2.
  • The Promag 200 series meets IEC 61508 SIL, ANSI and NAMUR safety requirements.
  • The output of the Promag 200 series is a two-wire, 4–20mA signal with HART or a pulse/frequency/switch output.
  • The mag meters have local four-line text displays with touch control, guided menus, ‘make it run’ wizards for setting up applications and displays for information on causes and remedial measures.
  • All device data and device configurations are automatically saved in non-volatile memory in HistoROM modules in the transmitter housings.
