Sensitive but strong

​Sensitive but strong The TIDALFLUX2300F from KROHNE has got you covered.Backed by over 90 years of expertise in flow measurement, there’s a KROHNE meterfor every job. The TIDALFLUX†2300†F reliably measures flows in pipes filled to between10†% and 100†% of their inner diameter.Even fat and oil floating on the surface are not a problem for the […]

​O​VERVIEW OF MEASURING PRINCIPLES FOR LEVELSelection of the measuring principle When engineering a level installation, the appropriate measuring principle is first selected according to the application and its criteria (tank, bypass, stilling well, etc.). If possible, select the principle which meets all of ​the criteria required. The measuring principles are classified according to “non-contact” and […]
