Abstract: Provided is a print head, a system and method for pressure measurements and continuous control of a flowable material in a flow path. The system includes a pressure coupler comprising a body having a channel through the longitudinal center of the body, the channel spanning between a first opening and a second opening. The pressure coupler includes a membrane embedded in the body, wherein the membrane is contiguous with, and forms a region of, the channel. Material flowing through the channel imparts a force on the membrane, and the force is transferred from the membrane to a pressure sensor adjacent to the pressure coupler. The pressure coupler and sensor may be included in a print head, whereby the pressure of a flowable material is measured during dispensing from the print head. The pressure measurements are used for continuous feedback flow control of the flowable material through the flow path.
