Spring-balanced Servo Tank Gauges

These servo tank gauges use a spring-loaded mechanism to counterbalance the weight of the displacer, which is immersed in the liquid. As the liquid level changes, the displacer moves up or down, causing the spring to compress or expand. This movement is then converted into a signal that indicates the liquid level.

The spring balance ensures that the displacer remains in a neutral position, regardless of the liquid level, which helps improve the accuracy of the measurements. These servo tank gauges are often used in industries such as oil and gas, chemical processing, and water treatment, where precise level measurement is critical for safety and efficiency.
