Abstract: A gas pressure driven fluid pump having an electronic cycle counter. The pump has a pump tank with a liquid inlet and a liquid outlet. A switching mechanism is operative within the pump tank for switching to exhaust porting when the fluid level within the pump tank falls to a low level position and switching to motive porting when the fluid level within the pump tank rises to a high level position. An electrical counter circuit is operatively connected to the pump tank for incrementing a stored count in response to the fluid level within the pump tank rising to a predetermined level.

Abstract: Various functions of a production oil well are monitored to cause a switch closure for each normal cycle of the pump. Alternatively, the level of the fluid within the well is monitored to cause the switch closure. The switch closure activates a first oscillator whose count is compared with a variable frequency oscillator over a given period of time to ascertain the percentage of time of normal operation. The integrated time is adjusted to shut down the system when the percentage of time drops to or below the preselected amount. In response to the integration timer signal, a shutdown timer is turned on which restarts the cycle after a preselected amount of time. When the system is restarted by the shutdown timer, a pump-up timer is turned on which is adjusted to allow for a desired pump-up time. As the pump-up timer is allowing the system to recycle, the integration timer is reset and the recycling is completed if the requirements of the integration timer are met. Otherwise, the unit is shut down again and the system recycled. A variable electronic scaler is connected to the output of the integration timer which monitors the output signals from the integrator timer. After the preset number of times the integration timer produces a signal, unless reset by a normal cycle, the scaler turns off the whole system. It can then be restarted manually.

Abstract: A valve in the production flow line of an oil well closes a reed switch indicative of fluid being pumped through the line. The switch closure activates a first oscillator whose count is compared with a variable frequency oscillator having a frequency of approximately one half that of the first oscillator. The comparison is made over a given period of time to ascertain the percentage of time the valve has been open and passing fluid. Theoretically, the valve should be open 50 percent of the time because 50 percent of the time is taken on the downstroke of the pumping assembly when no production is occurring. The integrated timer is adjusted to shut down the system when the percentage of time the valve is open drops to the preselected amount, usually equal to or less than 50 percent. In response to the integration timer producing a signal, a shutdown timer is turned on which restarts the cycle after a preselected amount of time. When the system is restarted by the shutdown timer, a pump-up timer is turned on which is adjusted to allow for a desired pump-up time. As the pump-up timer is allowing the system to recycle, the integration timer is reset and the recycling is completed if the requirements of the integration timer are met. Otherwise, the unit is shut down again and the system recycled. A variable electronic scaler is connected to the output of the integration timer which monitors the output signals from the integrator timer. After the preset number of times the integration timer produces a signal, the scaler turns off the whole system. It can then be restarted manually. This provides a safety device for equipment failure such as breaking of the sucker rod. Means are also provided for recording the various timed cycles and also for monitoring the number of signals transmitted to the scaler, thus being indicative of the number of times the system has automatically shut down.

Abstract: A landfill pump cycle counter includes a housing defining an internal passage, a poppet disposed within the internal passage, a magnet disposed within an internal cavity of the poppet, a counter, a seat formed on an inner surface of the housing, and a mating surface formed on the poppet. The landfill pump cycle counter is configured to receive liquid output from a landfill pump. The housing extends along an axis and also defines an inlet and an outlet. The internal passage fluidly connects the inlet to the outlet. The poppet is configured to be moved axially between an open state and a closed state. The counter includes a magnetic sensor configured to detect a poppet cycle. The poppet cycle includes the poppet moving from one of the open state and the closed state to the other of the open state and the closed state.

Abstract: An adhesive dispensing system includes a pump and at least one sensor positioned to sense movements of a component of the pump and produce signals based on the sensed movements. The dispensing system also includes a controller communicating with the at least one sensor to collect information regarding operational cycles of the pump based on the signals. As a result, one or more diagnostic processes are enabled at the controller during operation of the adhesive dispensing system. These diagnostic processes may include a leak rate test for the dispensing system, an overspeed detection test for the pump, and expected life cycle monitoring of the pump or other components.

Abstract: The device for counting the strokes of a piston sliding within a cylinder comprises a support housing a magnet which generates a magnetic field. The support also houses a sensor arranged to sense the magnetic field, such that the passage of the piston into a position corresponding with the magnet causes a disturbance in the magnetic field, which is sensed by the sensor, to indicate a stroke of the piston.

Abstract: A pressure tank fault detector and method provides a system for detecting a fault in a pressure tank, such as a well water tank. The system includes a current transformer positioned adjacent a pump power wire. A circuit includes a timer, a data recorder, and a system status indicator. When the pump operates, the current transformer sends a signal to the circuit and the timer measures the signal duration. The data recorder logs a short cycle when the timer measures less than a selectable predetermined amount of time. When two or more short cycles are recorded, a signal indicates that a tank fault has been detected. Preferably, the system includes a test circuit and permits a user to select the number of short cycles before the alarm and whether to record only consecutive short cycles. Optionally, the system detects and signals pump cycles that exceed a predetermined excessive run time.
