Flow Measurement
Electromagnetic
Universal measuring principle for all conductive liquids. Virtually independent of pressure, density, temperature, viscosity and flow profile. Even liquids with solids can be measured, e.g. ore slurry or cellulose pulps. Over 3 million Endress+Hauser magmeters installed since 1977! Sizes: DN 2 to 3000 (1⁄₁₂ to 120″).

Coriolis
Universal measuring principle for liquids and gases. Multivariable sensors: simultaneous and direct measurement of mass flow, density, temperature and viscosity. Independent of the physical fluid properties. Sizes: DN 1 to 400 (1⁄₂₄ to 16″) [max. 4100 t/h].

Ultrasonic
Volume flow measurement of liquids and gases, regardless of electrical conductivity with either clamp-on or inline sensor types. Ultrasonic measurement enables cost-effective and reliable flow metering anywhere in the process: volume, corrected volume, mass flow, sound velocity. Retrievable diagnostic values. Special devices for measuring wet or dirty gases at low pressures, e.g. biogas or landfill gas. Sizes: DN 15 to 4000 (½ to 160″).

Thermal
Direct mass flow measurement of gases with low process pressure up to 40 bar. Measuring principle with a high operable flow range (100:1) and an excellent low-end sensitivity. Patented bidirectional flow measurement and drift-free sensor. Short inlet runs with integrated flow conditioner. Negligible pressure loss. Sizes: DN 15 to 1500 (½ to 60″).

Vortex
Universally applicable for the measurement of liquids, gases and steam. Extremely robust with regard to external vibrations, dirt, water hammer and temperature shocks. High long-term stability, no zero point drift. Efficient steam plant operation thanks to the worldwide unique measurement of dryness fraction. Multivariable thanks to integrated pressure and temperature compensation. Sizes: DN 15 to 300 (½ to 12″).

Differential Pressure
Universally applicable for liquids, gases and steam up to 420 bar (6092 psi) and 1000 °C (1832 °F). Robust primary element as it is completely mechanical with no moving parts. The transmitter can be replaced during operation, e.g. for maintenance or modernization of the measuring point without interrupting the process. Sizes: DN 10 to 12000 (3⁄8 to 480″).
