Level measurement in a process vessel
过程数据
测量任务:
Level measurement and pressure measurement
测量点:
Tank
测量范围至:
0 … 5 m
介质:
Acids and alkalis

特殊挑战:
Aggressive media with different measurement properties
应用范围
To ensure the best possible fermentation of the ingeredients, optimal process conditions must prevail, control of pH value and temperature of the medium play important roles. The pH is adjusted by adding acids or alkalis, and sodium hydroxide is used to clean the vessel under absolute sanitary conditions. The levels of the process vessels have to be monitored at all times, to ensure continuous operation of the system. The measured media place very high demands on the chemical resistance of the sensors. To be totally reliable, the instruments need to be equally resistant to both acids and alkalis.
