Reliable Level Measurement for Buffer Tanks with Radar Level Meter and Vibrating Level Switch

In industrial production, buffer tanks and storage tanks are crucial to ensure continuous production and stable material supply. To maintain smooth processes, operators must have real-time awareness of the liquid level inside buffer tanks, achieving both continuous level measurement and point level detection. Jiwei Automations provides a comprehensive solution with radar level meters and limit switches, combining high-precision measurement technology, high-temperature and high-pressure resistance, and intelligent functionality, perfectly meeting the complex operating conditions of industrial sites.

Key Challenges in Buffer Tank Level Measurement

Buffer tanks often contain complex and variable media, which may involve the following issues:

• Frequent medium changes: Differences in density, viscosity, and conductivity between batches can affect the stability of traditional instruments.
• Temperature and pressure fluctuations: High or low temperatures or pressure variations can lead to sensor drift, affecting measurement accuracy.
• High safety and protection requirements: Uncontrolled liquid levels may cause overflows or dry-run conditions, threatening production safety and equipment lifespan.

In this context, using high-performance radar level meters in combination with limit level switches enables both continuous level measurement and overflow/dry-run protection, ensuring production safety, efficiency, and reliability.
