Abstract
A metering device having a housing with a successively return bent fluid receiving passage therein, having a discharge end and an inlet end, being of substantially constant capacity sufficiently restricted to generate fluid movement by capillary attraction upon the application of fluid movement from the discharge end thereof; a transparent plate mounted on the housing in fluid-tight covering relation to the passage; a coupling borne by the plate in communication with the discharge end of the passage for connection to a fluid consuming means in fluid transferring relation; and a scale borne by the plate against which fluid received in the passage can be read to reveal the time required to consume the fluid.
Claims7
A metering device comprising a housing having an elongated reservoir, with a metering end, for fluid to be metered, dimensioned to retain said fluid in an elongated coherent mass having a terminal end remote from said metering end wherein said reservoir has a transverse dimension which is sufficiently small to generate movement of said coherent mass by capillary attraction therethrough during metering and wherein the elongated reservoir is successively return bent in the housing to extend in substantially parallel sections to provide a compact device;
- and means mounted on said housing in covering relation to the reservoir for making visible said fluid within the reservoir and for displaying reference means against which said terminal end of the fluid can be read to indicate the time required to meter said fluid and said parallel sections of the reservoir are substantially right-angularly related to said reference means to facilitate the reading of said terminal end of the fluid against the reference means.
A metering device adapted for connection to a fluid consuming means, the device comprising a housing having a successively return bent passage therein of substantially constant width having a discharge end and being sufficiently narrow to generate fluid movement by capillary attraction upon the initiation of fluid movement from said discharge end;
- a transparent plate mounted on the housing in fluid-tight covering relation to said passage, and a coupling borne by the plate in communication with the discharge end of the passage for connection to the fluid consuming means to initiate said fluid movement from the discharge end.
