Abstract
In recent years, the need for reliable and continuous level measurement in industrial processes has significantly increased. The hydrostatic method, known for its simplicity and accuracy in measuring liquid levels, plays a vital role in ensuring operational safety and efficiency. Alongside this, the FISCO (Fieldbus Intrinsically Safe Concept) approach has emerged as a key solution for enabling intrinsically safe installation of level sensors in hazardous environments. Advanced technologies such as radar, ultrasonic, and electromagnetic wave-based sensors, combined with digital communication protocols like HART and PROFIBUS-PA, allow for real-time data transmission and process optimization. These innovations contribute to enhanced control, resource efficiency, and reduction of potential risks in modern automation systems.
