Muller, a UK yoghurt brand, has reduced overfill of its Muller Corner products by 84% by installing Krohne’s Batchflux new electromagnetic flow-meters. The company has since ordered additional instruments for installation on a second production line. At the Muller Corner production line in Shropshire, pots are filled at the rate of 276 per minute, 24 hours per day. The yoghurt flows through stainless steel pipes from storage tanks into a hopper and is then pressure fed through the flow-meters where it is dosed into each pot. A pulsed output is taken from the Batchflux which equates to 1ml of yoghurt for every ten pulses. Pulses are fed to a PLC which counts the pulses and controls the rate at which yoghurt is dosed into pots. It can measure both liquids and liquids that contain solids.
