A NEW SIGHTLY BENT SINGLE TUBE CORIOLIS MASS FLOWMETER FOR CORROSIVE FLUIDS

Martin Anklin, Alfred Wenger

Abstract

Commercially available Coriolis mass flowmeters (CMF) show a broad variety of designs, which range from single to dual straight or bent tubes. The new single tube mass flowmeter presented in this paper is slightly bent. The advantage of bent tubes is that thermal stresses are reduced and that the instrument is capable to measure fluids up to 200°C. Furthermore, the slightly bent tube can easily be drained completely. Since the fluid is in contact only with zirconium R60702, mass flow can be determined for a wide variety of corrosive mediums. In particular, zirconium is used for hydro-chloride (HCl) applications, where it does not show corrosion even at high concentrations or at elevated temperatures of HCl. <BR />This paper illustrates the working principle of the new single tube CMF and shows its experimental performance.
