Custody transfer measurement of sugary syrup

Application Report | Food & Beverage

  • Measuring system as per MID MI-005
  • Mass flow measurement of sugary syrup
  • Space-saving installation with straight tube design


UNIFERM is a domestic and international supplier of ingredients for bakeries. The company supplies the bakery trade and baking industry with a comprehensive range of products including baking yeast, baking agents for bread and rolls, baking agents for fine pastries and separating agents.

Measurement requirements

Sugary syrup is used as a raw material in the production of yeast. This syrup is subject to custody transfer in accordance with MID 2004 / 22/EC MI-005. Measurement of the liquid sugar must conform to these requirements. Local installation conditions are taken into account and the data is made available to regulatory authorities. A Coriolis mass flowmeter was chosen due to limited space on-site and the required measuring range in which the system operates.

KROHNE Solution

KROHNE provided a Coriolis mass flowmeter OPTIMASS 7300 C. It was supplied in a compact version featuring a Titanium measuring tube (DN 25). The OPTIMASS 7300 boasts a single straight measuring tube and was thus able to be installed very compactly in a confined space. The general requirements for measuring systems for liquids other than water were taken into account. The measuring system's compact design meant that having no inlet run was a possibility.

Customer benefits

The OPTIMASS 7300 C meets all custody transfer requirements according to OIML R117 and MI-005. The high linearity of the mass flowmeter as well as the associated maximum measuring accuracy allow for highly precise measurement in the specified measuring range while reducing costs for calibration.
