E+H Proline Promag L 400 Electromagnetic Flow Meter

The E+H Proline Promag L 400 electromagnetic flow meter measures volume flow, conductivity and mass flow. It features a weight-optimized sensor that is up to 30% lighter than traditional sensors and a unique lap-joint flange which makes it an ideal solution for standard water and wastewater applications. The bidirectional measuring principle is not dependent on pressure, density, temperature and viscosity. Because it has no moving parts, the Promag L 400 is maintenance-free and applications suffer no pressure loss due to cross-section constriction.

E+H transmitters do not require proprietary communication system, rather they offer full access to process and diagnostic information via numerous, freely combinable I/Os and fieldbuses. The L 400 allows for up to three analog or digital outputs. Digital communication options include HART, PROFIBUS DP, EtherNet/IP and Modbus RS485. This E+H flow meter is housed in an IP66/67, Type 4X enclosure standard, while IP68, Type 6P protection is also available as an option for the remote sensor.

The E+H Proline Promag L 400 electromagnetic flow meter can measure flow from 2.5 gal/min up to 1030 Mgal/d and can handle a variety of media temperatures, depending on liner material. Three liner materials are available including hard rubber (32 to 176°F), polyurethane (-4 to 122°F) and PTFE (-4 to 194°F). The standard maximum measured error is ±0.5 % of reading ± 1 mm/s and the Proline Promag L 400 offers an improved accuracy of ±0.2 % of reading ± 2 mm/s. Optional Heartbeat Technology ensures compliance and process safety at all times.
