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
