Product Overview

The ADDA-LE-66 Series RF capacitance level meter is used for liquid, oil, glue, solid, and interface measurement. The product details describe no moving parts, reliable long-term operation, high sensitivity, good linearity, high-temperature resistance, and high-pressure resistance.

Applications

Product details include petrochemical, metallurgy, electric power, paper-making, pharmaceutical, and other fields.

Working Principle

The capacitance level meter detects level by measuring changes in capacitance. It consists of two electrodes: one electrode is generally located at the bottom of the vessel and connected to ground potential, while the other electrode is located on the vessel wall and connected to the capacitance meter.

When capacitance forms between the electrode in the liquid and the outer wall electrode, changes in liquid level cause the capacitance value to change. The digital processing circuit uses this change to calculate the corresponding level height for real-time monitoring.
