Frequently Asked Questions
How do KROHNE Coriolis mass flowmeters handle entrained gas in liquid streams?
KROHNE's advanced OPTIMASS series features Entrained Gas Management (EGM) technology, which utilizes robust digital signal processing to maintain measurement stability even with gas fractions up to 100%. This ensures continuous, accurate mass flow and density measurement during challenging multiphase flow transitions in chemical and food processing.
Are KROHNE electromagnetic flowmeters suitable for measuring low-conductivity fluids?
Traditional electromagnetic flowmeters require a minimum conductivity; however, KROHNE's WATERFLUX and OPTIFLUX series are engineered with specialized high-impedance electronics to measure fluids with conductivities as low as 1 µS/cm. For entirely non-conductive fluids like hydrocarbons, KROHNE recommends their ultrasonic or Coriolis flowmeters.
What makes the KROHNE OPTIFLEX guided radar ideal for turbulent level measurement?
The OPTIFLEX guided radar utilizes Time Domain Reflectometry (TDR) to send electromagnetic pulses down a probe, making it highly immune to surface turbulence, foam, and fluctuating vapor pressures. This robust design guarantees accurate, reliable continuous level measurement in turbulent reactor vessels and agitated storage tanks.
How does KROHNE ensure calibration accuracy for large-diameter ultrasonic flowmeters?
KROHNE operates some of the world's largest volumetric calibration rigs, allowing them to precisely calibrate large-diameter ALTOSONIC flowmeters under real-world hydraulic conditions. This rigorous wet calibration process guarantees exceptional accuracy and traceability for custody transfer applications in the oil and gas pipeline sector.
Can KROHNE temperature assemblies be serviced without shutting down the process line?
Yes, KROHNE OPTITEMP assemblies are frequently supplied with precisely machined thermowells that isolate the measuring insert from the pressurized process medium. This design allows instrumentation technicians to safely remove, recalibrate, or replace the RTD or thermocouple sensor without requiring a process shutdown.
