Fluid reservoir with fluid-level sensor

摘要

A fluid reservoir with a fluid-level sensor includes a manual testing device consisting of two separate but cooperative rods. The fluid-level sensor consists of a float within the reservoir and a reed switch which is closed to cause a low fluid-level alarm when the float is lower than a predetermined level. The testing device serves to depress the float to below that level to ensure that the switch and the alarm are working. A first rod is supported by a filter mounted at the top of the reservoir. A second rod is supported by a flexible cover which fits over the top of the reservoir. The rods are coaxial and free to move downward far enough to push the float to below the above level. Having the two rods separable allows the cover to be removed easily without damaging the manual testing device.
