Filling Level Meter
Introduction
Filling level sensors are crucial for reliably monitoring the contents of tanks and containers, whether liquids, powders, or bulk solids. They play a key role in ensuring process efficiency, preventing overfilling or shortages, and enabling automated control in industries such as manufacturing, food and beverage, water treatment, and logistics.
Among the various technologies available - such as ultrasonic, capacitive, and optical - radar sensors offer the highest precision, reliability, and versatility. Immune to dust, vapors, and temperature fluctuations, radar is the optimal choice for demanding industrial environments and ensures accurate measurements even under challenging conditions.
