These are very common widgets for pure HMI (Human-Machine-Interface) in the process control industry. Many (most?) implementations allow both ends to be set, and allow those end points to either be higher or lower than the other, and that determines the directions. Added bonus points; Some "liquid"-style meters also allows a "zero" (auto placed in its linear position between the ends) and the 'liquid' grows from the zero to the current value.
