    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 operating the pump and 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: A liquid pump control system for dry run avoidance and re-prime detection. Pump dry run conditions can be detected with improved sensitivity by measuring pump cycle speed. Pump cycle speed is determined from sensors including pressure sensors, diaphragm end of stroke indicators, check valve movement sensors, and other techniques. A controller closes a valve to reduce pump cycle speed by reducing drive air pressure or by deadheading the pump liquid outlet. When the pump re-primes, the valve is opened, pump cycle speed increases, and pumping volume flow rate increases until a dry run condition is again encountered. Time delays can be introduced to delay shutting down or restarting the pump, for example to give a liquid source tank time to refill. The improved control sensitivity provides improved shut-down and re-start performance, reducing wear on the pump and reducing wasted drive air and energy consumption.

    Abstract translation: 一种用于干运行回避和重新检测的液体泵控制系统。 通过测量泵循环速度可以提高泵的干运行条件，提高灵敏度。 泵循环速度由传感器确定，包括压力传感器，行程指示器的隔膜端，止回阀移动传感器和其他技术。 控制器关闭阀门，通过减少驱动空气压力或者使泵液体出口处于不合适的位置来减少泵循环速度。 当泵重新启动时，阀打开，泵循环速度增加，并且泵送体积流量增加，直到再次遇到干运行状态。 可以引入时间延迟来延迟关闭或重新启动泵，例如给予液体储罐时间以重新填充。 改进的控制灵敏度提供了更好的关闭和重新启动性能，减少了泵上的磨损，并减少了浪费的驱动空气和能量消耗。

    Abstract: A simplified system and method for remotely monitoring and optionally further controlling pumpjack operating parameters of a pumpjack located at a distant site but within wireless cell phone station reception. Sensors situated on a pumpjack monitor and create analog output of operational conditions of the pumpjack. Digitizing means digitize the analog output of the sensors to digital data, and modem means transmit the digital data via a wireless cellular network to a network server. A user's computer communicates with the network server via the internet, and accesses the digital data to obtain information regarding the operational conditions of the pumpjack.

    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.
