Milk is both a staple food worldwide and a key ingredient in many non-food products such as cosmetics. From the collection of the milk from the dairy right through to the formulation and processing of the final product, measurement is an important function for sales volume calculation, inventory control and precise process control to ensure product quality and repeatability.

But, milk products come in many different forms with different densities, viscosities and flow characteristics that can make accurate measurement difficult. However, by using electromagnetic flow meters to do the measuring, many of the difficulties can be overcome. Electromagnetic flow meters can be used with:
  • Whole milk and raw milk.

  • Standardized milk of 0.3 percent to 3.8 percent fat.

  • Ewe’s and goat’s milk.

  • Soy milk.

  • Extended shelf life (ESL) milk.

  • Condensed milk and coffee cream.

  • Cream.

  • Yogurt and kefir.

  • Buttermilk and soured milk.

  • Whey.
The same metering devices may be used to measure accurately the quality of milk collected by the road tanker in accordance with weights and measurement regulations; during processing to accurately measure and control flow rates and additive dosing levels (for example fruit); and control the filling process at the end of the production chain. Electromagnetic flow meters do not have any moving parts and are suitable for use at high temperatures or under vacuum conditions.

GEA Diessel offers an electromagnetic flow meter technology that includes Bluetooth technology for remote data collection, automatic calibration and a design compatible with aseptic processing.
