To ensure the preservation of milk quality and prevent degradation, efficient monitoring of milk silo levels in a centralized location is crucial.
Introduction
The milk factory has a large capacity silo to store raw milk and intermediate products during processing and packaging of dairy products. To keep them fresh in silos and to prevent deterioration, it is necessary to continuously monitor the level and temperature in the silo.

Process Description
- The end-user wanted to build a remote system to continuously monitor levels in many silos.
- To preserve the freshness of raw materials, it is necessary to use the same quantities in all silos. Therefore, it is necessary to keep a record of the level in each silo.
- Currently, the level is recorded twice daily, manually, but it takes time and manpower and there is a risk of recording bad data.
Application Solutions
- By connecting a Yokogawa FN 310 Multiprotocol Module and FN 120 Communication Module to the HART transmitter installed in each silo, it is possible to transmit the process variable value and self diagnostic information with ISA 100 Field Wireless.
- The paperless recorder logs the data transmitted from the wireless devices.
- The paperless recorder can be accessed from the user's LAN environment, and it is possible to continuously monitor with a web browser.

and the GX10/GX20 Paperless Recorder.
Conclusion
- Monitoring all silo levels from one location makes it possible to use an equal amount of raw milk for each silo and reduce the risk of degradation of the raw milk.
- The HART transmitter connected to the FN 310 is driven by the built-in battery, eliminating the need for power supply equipment and wiring.
