How do you choose the right type of flowmeter? Consider the medium, the operating conditions and the accuracy you need.
When selecting a flowmeter, consider the characteristics of the medium (viscosity, corrosiveness, conductivity), the operating conditions (temperature, pressure, explosion‑proof requirements) and the required accuracy together.
Electromagnetic flowmeters suit conductive liquids, have no moving parts in the measuring tube and cover nominal sizes from 15 to 2200 mm with 0.3 to 0.5% accuracy, for water and wastewater, chemical, steel and mining applications. Turbine flowmeters suit low- to medium‑viscosity liquids such as water, emulsions, glycol mixtures and light oils, with medium temperatures from -60 to +350 °C.
For high‑accuracy needs such as custody transfer, the Coriolis mass flowmeter measures mass flow directly with a basic accuracy (mass flow) of ±0.1%, while the twin‑rotor positive displacement flowmeter reaches 0.1% accuracy for demanding metering applications.
Our electromagnetic, turbine and Coriolis flowmeters are all available with ATEX, IECEx and other international explosion‑proof certifications for hazardous areas on ships and in chemical plants. Send us your process parameters and we will recommend the most suitable solution.
