Surge tanks are often located between process units to help reduce the effects of flow variations between interconnected process units. A buffer tank level that is too low can result in reduced production, while a level that is too high can cause liquid material to be carried over. In applications characterized by alternating inertia and turbulent flow, a stable level output is highly desirable.

Challenge:

Contrary to the purpose of conventional control, which keeps the measured value stable at a set point, the purpose of buffer tank level control is to dampen changes in the controlled flow rate while maintaining the liquid level in the vessel between upper and lower limits. For surge tanks, it is usually more important to allow the liquid level to “float” in order to minimize flow variations.
