Coriolis and electromagnetic flow instruments optimised for maximum safety, enhanced measurement quality and device accessibility.

Endress + Hauser’s Proline 300/500, a family of industry optimised “smart” Coriolis and electromagnetic flowmeters, simplify installation, speed commissioning and streamline operation and maintenance.

Promass flowmeters are available in 11 models ranging in sizes from 1/24 to 14 inches in diameter, for measuring flows up to 100,000 tons per day. Promag flowmeters are available in three models in sizes from 1/12 to 90 inches for volume flows up to 634 million gallons per day. Both are available in models suitable for high temperatures, corrosive fluids, hygienic and sterile process applications.

Proline 300/500 allows universal flow metering in all applications in the process industry – from basic process monitoring up to custody transfer applications. Proline provides a view into the process; plant operators receive a wealth of important diagnostic and process data. End users benefit from optimal process monitoring, fewer periods of downtime and more efficient process control.

Proline 300/500 transmitters can be freely combined with any of the Promass and Promag sensors. Several process variables can be measured simultaneously using only one device – for example mass flow, volume flow, density, viscosity and temperature (Coriolis); or volume flow, temperature and conductivity (electromagnetic). Each device is checked using accredited and traceable calibration facilities (ISO/IEC 17025).
