Testing Optical Time-of-Flight Distance Sensors to Monitor Milk Levels
Having already investigated a solution using Terabee’s Time-of-Flight digital sensors to accurately measure stock levels in silos, Terabee conducted a feasibility study that successfully demonstrated a new solution for measuring opaque liquid levels.
The challenges of measuring opaque liquid levels
With feed and milk prices continuously fluctuating around the globe, dairy farmers and the dairy industry are under pressure to remain profitable. There are also increasing regulations, especially those governing electronic records, that set stringent requirements for accuracy, reliability and electronic reporting, triggering new demand for innovative milk level monitoring technologies.
Introducing Terabee’s Time-of-Flight technology for stock level monitoring
Terabee’s engineers simulated a milk vat in the lab. The container was mounted on a flat surface and a Terabee Evo 3m sensor was then mounted on a fixed test platform with its Field of View pointing towards the bottom of the empty container.
The Evo 3m was selected from our range of digital distance sensors as milk vats often require shorter range measurements with increased accuracy and precision.
The Evo 3m milk level monitoring sensor features a narrow 2° Field of View allowing customers to precisely point the sensor to a preferred milk surface area, and avoid hitting other machinery in the container, such as stirring equipment. The sensor was connected to a Windows PC running H-Term emulation software to gather raw distance data of the milk level within the container.
The study’s results reveal that Terabee’s Time-of-Flight distance sensors can clearly detect the surface of the milk and provide an accurate measurement of both static and continuous free-flowing opaque liquid.
Real-time and recorded distance data can be quickly turned into level or remaining volume estimations. This can then be used to provide information that is essential for stock and transport planning, as well as optimizing production processes. Milk producers also benefit from reduced labor costs associated with manual fill-level inspections and estimations. The data provides reliable stock level records and traceability that are critical within this heavily regulated and competitive industry.
• Contamination free - no direct contact with the material
• Real-time data, react fast to emergency situations (e.g leakage)
• Small footprint for installation
• No moving parts that require maintenance
• Continuous measurement of either static or free-flowing liquid
• Reliable and accurate measurements - no acoustic issues inside tanks
