One of the indirect benefits of accurate density measurement is more accurate concentration measurement of mixtures and solutions, such as oil and water mixes or sugar solutions. The corresponding concentration values are displayed, as a percentage or in °API, °Brix or °Baume units, and can be integrated into the process control system via analogue or digital signals.
Traditionally the mass flow output from Coriolis meters responds in a highly sensitive manner to gas bubbles in liquids. The ROTAMASS, on the other hand, has a special sensor design which can tolerate a relatively high proportion of gas in the medium. Diagnostic functions also enable the detection of gas bubbles contained in the liquid, so that an appropriate response can be initiated, guaranteeing functionality even at high gas concentrations.
Many applications involving highly viscous media (for example asphalt) require high process temperatures in order to lower the viscosity of the medium for pumping purposes. To avoid cooling of the medium, the mass flowmeter requires special insulation and heating. This is a particular strength of the ROTAMASS flowmeter, which can handle applications involving temperatures of up to 350°C.
