TEMPERATURE COMPENSATION APPARATUS FOR A LIQUID FILLED CONDUIT

摘要

V. N. Lawford - 12 TEMPERATURE COMPENSATION APPARATUS FOR A LIQUID FILLED CONDUIT A liquid level system having a bellows biased with a spring having a constant to add a variable force to a water column of a magnitude-substantially equal to a loss in pressure resulting from an increase in water temperature. Such a system may also have high and low pressure connections to corresponding bellows and springs. The reference column may also be large in comparison to the remainder of the capillaries.
