High performance instruments for the flow measurement of liquids, gases and steam


Universal measuring principle for all conductive liquids
Virtually independent of pressure, density, temperature and viscosity
Even solid-containing liquids can be measured, e.g. ore slurry, cellulose pulps
Sizes: 1/12” to 90”


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: 1/24” to 16”


Volume flow measurement of clean liquids or wet biogas
Liquid version in either clamp-on or in-line sensor type
Ultrasonic measurement enables cost-effective and economical flow metering for process.
Two-wire versions simplify installation concept.
Sizes: 1/2” to 160”


Direct mass flow measurement of gases with low process pressure up to 600 psi
Measuring principle with a high turndown (100:1) and an excellent low-end sensitivity
Negligible pressure loss
Sizes: 1/2” to 60”

Differential pressure

Universally applicable for liquids, gases and steam up to 420 bar and 1000°C
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: 1/2” to 160”


Universally applicable for the measurement of liquids, gases and steam
Extremely robust with regard to external vibrations, dirt, water hammer and temperature shocks
Largely independent of changes in pressure, temperature and viscosity
High long-term stability, no zero point drift
Sizes: 1/2” to 12”
