Centec Rhotec in-line density monitor

Monday, 31 March, 2014 | Supplied by: B-R Controls Pty Ltd


The Rhotec in-line density monitor continuously measures the density of liquids. Centec, a German-based company, designed the Rhotec for maximum sensitivity and high accuracy.

The Rhotec can be used in the food industry, breweries, beverage plants and pharmaceutical plants to determine the concentration of alcohol, sugar contents, acids, caustics and other solutions. For density measurement, the liquid flows through an oscillating U-shaped tube; any change in the fluid density causes a change in the oscillating frequency and is used to determine the density. As a specific property of each liquid, the correlation between concentration and density can be described by a mathematical polynomial.

With decades of experience and its own laboratory facilities, Centec has the polynomials for a large number of liquids. Temperature changes of the measured liquid are automatically compensated for by an internal Pt1000 sensor.

The Rhotec displays various units, e.g. vol.%, mass %, °Brix and °Plato. The Rhotec has a SS316 housing and is available with a range of wetted part materials to suit most liquids. A range of communication options exist to interface with PLCs and DCS systems.
