KRAL Flowmeters OMG Series
Universal device for manifold application needs. Due to their continuous ongoing development, the highly modular OMG series covers a broad range of applications. KRAL Flowmeters OMG Series is therefore particularly suitable for manifold applications, such as mechanical engineering, chemical engineering, and marine.
The flow meters OMG series also combines robustness with the highest precision, characteristics for which KRAL flow meters are well-known worldwide. Due to the screw pump principle, all OMG series devices are very smooth-running and fast and can follow quick, pulsation-related changes in flow rates. Due to their extremely robust construction, the OMG series provides optimal protection against external influences, such as system vibrations and mechanical stresses in harsh environments.
Benefits:
- Wide range of applications that have a manifold need for flow measurements, such as mechanical engineering, chemical engineering, and marine.
- High-precision flow meter.
- Extremely robust.
- Stabilization zones are unnecessary.
- Easy installation.
- Very smooth-running, follows any rapid fluctuations in the flow caused by pulsations
- Low friction and minimal loss of pressure.
