Risk Assessment of Milk Foam Influence on Level Measurement

Dairy

A dairy produces rice milk in a permanent process with 2000 l of milk per hour. Previous measuring systems could not distinguish properly between milk-rice mixture and foam in the feed tank.

Consequences

• The supply of milk and rice could not be precisely controlled
• The level in the reserve tank repeatedly dropped to zero
• The plant shut down in the middle of the production process to protect the pumps
• The product remaining in the process overheated and became unusable

Application Detail

The Experienced Damage

The rice milk production stopped in the middle of the process.

• The entire run of product which was still in the process was lost, meaning the loss of several thousand liters of rice milk
• 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

The Solution

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 50mm to 3000mm height and process temperatures up to 140° C
• Many options for individual adaptation
