Flowmeter helps cut overfill
November 1st 2005

Müller has reduced overfill of üller Corner yogurts at its Shropshire site by 84% since installing Krohne's Batchflux electro-magnetic flowmeters.

Pots are filled at the rate of 276/min, 24h/day, so the company needed to ensure the 400 000 yogurt pots filled per day are not underfilled, but also needed to ensure that overfill is kept to a minimum.

Müller previously used flowmeters that were not sufficiently accurate and that were costly and time consuming to repair. The Batchflux units have reduced overfill to an average of less than 0.5gm per pot - eight times better than previously achieved.

Yogurt flows through stainless steel pipes from storage tanks into a hopper and is then pressure fed through the flowmeters where it is dosed into each pot.

A pulsed output is taken from the Batchflux that equates to one millilitre of yogurt for every 10 pulses.

Pulses are fed to a PLC that counts them and controls the rate at which yogurt is dosed into pots.
