A flow sensor includes a fluid chamber configured to receive a fluid. A diaphragm assembly is configured to be displaced whenever the fluid within the fluid chamber is displaced. A transducer assembly is configured to monitor the displacement of the diaphragm assembly and generate a signal based, at least in part, upon the quantity of fluid displaced within the fluid chamber.

A system for monitoring flow conditions of fluid flowing from a product container through a solenoid pump. The system includes at least one solenoid pump comprising a solenoid coil, which, when energized, produces a stroke of the solenoid pump, at least one product container connected to the at least one solenoid pump wherein the at least one solenoid pump pumps fluid from the at least one product container during each stroke, at least one PWM controller configured to energize the at least one solenoid pump, at least one current sensor for sensing the current flow through the solenoid coil and producing an output of the sensed current flow, and a control logic subsystem for controlling the flow of fluids through the solenoid pump by commanding the PWM controller and for monitoring the current through the solenoid pump by receiving the output from the current sensor, wherein the control logic subsystem uses the measured current flow through the solenoid coil to determine whether the stroke of the solenoid pump is functional.

Systems and methods related to a flow meter and/or flow meter operation can include one or more sensors and be capable of detecting parameters of the fluid flowing the flowmeter. One or more sensors can include capacitive sensors having a plurality of electrodes and configured to detect capacitive properties of a fluid flowing through the flow meter. Detected changes in detected properties of the fluid can be evidence of important changes in the fluid, such as an out of product event or a contamination of the fluid.

In one embodiment, the present disclosure includes a dispenser vane comprising a flexible outer surface and a plurality of flexible teeth arranged along the length of the outer surface. The flexible outer surface and flexible teeth are radially moveable.

A liquid pumping device (1) for beverage dispenser comprising: -a housing (2) with a liquid inlet (3) and a liquid outlet (4); -a gear pump (5) positioned in the housing with the liquid inlet communicating with the gear pump; wherein a flowmeter (6) is fluidly positioned in the housing (2) preferably between the gear pump (5) and the liquid outlet (4).

A hot melt adhesive system includes an adhesive supply for receiving solid or semi-solid hot melt adhesive, and a heater associated with the adhesive supply for melting the solid or semi-solid hot melt adhesive into liquid hot melt adhesive. An adhesive tracking system monitors an output of the liquid hot melt adhesive, and includes a flow meter having a flow inlet and a flow outlet. The flow meter measures an amount of the adhesive flowing out of the flow outlet. A product detector may be used to sense a presence of a product to which the adhesive is applied. A controller then determines the total amount of the liquid adhesive dispensed and the average amount of liquid adhesive dispensed per product.

In a flow meter with a displacement meter (1) a parallel-connected pressure difference sensor (3) has a bypass channel (8) which frees a connection between the inflow side and the outflow side (4, 5) when a piston (7) butts against a maximum stroke stop (9). In the bypass channel (8) is a check valve (11) which prevents the backflow from the outflow side to the inflow side (5, 4) and thus enables a return of the piston (7) purely due to pressure.
