Abstract: PROBLEM TO BE SOLVED: To eliminate necessity of an independent reaction agent level sensor. SOLUTION: A fluid delivery system for delivering a metered dose of fluid from a supply tank 28 to a downstream chamber or vessel 10, comprises a pump apparatus 20 comprising a pump plunger 32 which is operable to perform a pumping stroke under control of an electromagnetic actuator 36, including a solenoid 36a, to effect delivery of the fluid and a control unit 24 for supplying an input signal 58 to the solenoid to initiate a current flow to the solenoid and thereby initiate movement of the pump plunger. An electronic device 54 provides an output signal to indicate that movement of the pump plunger has stopped at an end of the pumping stroke of a pump plunger, and a timer determines a time difference between the input signal 58 being supplied to the solenoid and the output signal being output by the electronic device 54. A processor 26 compares the time difference with a predetermined time difference and determines, as a result of the comparison, whether or not the pump plunger has performed a valid pumping stroke in which an intended volume of fluid is displaced, whether or not the stroke can be used for total flow quantity calculation.

Abstract: The lubricant level within a reservoir is difficult to monitor, leading to the reservoir being refilled more often than necessary to ensure that the reservoir always contains lubricant. A lubricant level sensing system is connected to and monitors various aspects of the pump assembly that draws lubricant from the reservoir. The pump assembly displaces a known volume of lubricant with each pump stroke. A lubricant-level estimator calculates an estimated lubricant level remaining in the reservoir based on a stroke-count value as sensed from the pump assembly and on a reference value stored in a memory. The estimated lubricant level provides the lubricant remaining and the rate of usage such that maintenance can be scheduled ahead of time to prevent the reservoir running dry.

Abstract: A remote adhesive monitoring system is used in connection with adhesive applied to workpieces moving along a production line. A reservoir, pump, and applicator apply the adhesive to the workpieces. A monitor control computer has an associated data processing program. A pump cycle sensor senses pump cycles. An applicator sensor senses when the adhesive is applied to the workpieces. A workpiece sensor senses the workpieces moving along the line. The monitor control uses input from the applicator sensing means and the workpiece sensor to determine an ON time per each workpiece at a predetermined speed. The monitor control uses input from the workpiece sensor and the pump cycle sensor to determine the number of workpieces per pump cycle. The monitor control calculates an ON time to TOTAL time ratio per each workpiece, and will then calculate an amount of adhesive used for the given ON time to TOTAL time ratio.
