Abstract

A method of determining the concentration of a fluid in which the relationship between density and concentration of the fluid passes through either a maximum or minimum value, referred to as the turning point, before respectively either decreasing or increasing again. The method involves determining the viscosity of the fluid and relating this to concentration. The viscosity measurement is taken to establish on which side of the turning point the concentration measure occurs. Preferably the density of the fluid is also determined to improve the accuracy of the determined concentration value. The method can be applied to the measurement of sulphuric acid solution concentrations, which exhibit a monotonic relationship between viscosity and concentration at particular temperatures, and the measurements of density and viscosity can be performed using a single vibrating fork meter.
