What happens if milk foam causes wrong level measurement?
A dairy produces milk rice in a permanent process with 2000 l of milk per hour. The measuring systems used in the past could not distinguish precisely between milk rice mixture and foam in the feed tank.
• The sensor signalled “full”, although there was only foam in the supply tank
• No more milk was supplied
• The plant was clogged and switched off in the middle of the process
• The product remaining in the process overheated and became unusable
The milk rice production stopped in the middle of the process
» The entire product which was still in the process was lost, meaning the loss of several thousand liters of milk rice
» The plant had to be cleaned completely
» During the downtime of the plant for cleaning no production was possible, meaning the loss of several hours of production time
Precise, foam-independent level measurement with the NSL-F potentiometric level sensor
» Ideal for demanding applications with foam, pasty or highly adhesive media
» For vessels from 50 mm to 3000 mm height and process temperatures up to 140 °C (290 °F)
» Many options for individual adaptation
