ABSTRACT:
A device for indicating the interval for the flow of a predetermined volume of fluid. The fluid flow measurement device includes a housing having a cavity therein for being interposed along a fluid line. A flexible diaphragm having a convolution therein is included within the cavity for dividing the cavity into a first and second chamber. The flexible diaphragm prevents the flow of the fluid between the first and second chambers. A fluid port connects the second chamber to the fluid flow line. A fluid outlet connects the first chamber to the fluid flow line. The apparatus also includes a bypass for diverting the fluid flow from the fluid port of the second chamber through a fluid inlet into the second chamber, whereby the fluid flowing into the second chamber will displace the flexible diaphragm into the first chamber thereby expelling the predetermined volume of fluid from the first chamber.
