When float measurement is impractical within a vessel, where is the float typically installed?

The installation of a float in a float cage is a practical approach when direct measurement within a vessel is not feasible. A float cage allows the float to operate in a controlled environment, often using a protected area or enclosed structure that maintains consistent conditions. This setup helps ensure accurate level measurement without exposing the float to the potentially turbulent or variable conditions present inside a vessel.

In contrast, options like a diaphragm level indicator, differential head meter, or float manometer are designed for different measurement techniques and may not accommodate a float's movement or the specific conditions required for accurate level measurement as effectively as a float cage. A float cage is specifically tailored to house the float securely, providing reliable readings while isolating it from the vessel's internal dynamics.
