Accurate and real-time tank measurement is essential for industries handling bulk liquids such as oil, chemicals, and liquefied gases. Traditional gauging methods often fall short in precision, automation, and data accessibility. Digital servo tank gauges have emerged as a highly reliable solution, offering exceptional accuracy and continuous monitoring capabilities.
How Digital Servo Tank Gauges Work
Digital servo tank gauges operate based on a highly accurate force-balance principle:
- A displacer is suspended inside the tank by a wire
- A servo motor adjusts the position of the displacer
- The system detects changes in buoyancy as the liquid level changes
- The gauge calculates the exact level, interface, and density
This process ensures precise measurement even in demanding industrial environments.
Key Features of Digital Servo Tank Gauges
