Abstract
A displacement sensing device transduces deflection of a body disposed around a conduit into complementary signals indicative of the amount of displacement experienced by the conduit. The displacement sensing device includes a cuff and a sensor disposed on an outer periphery of the cuff, and may further include a controller in communication with the sensor, such that the controller receives signals from the sensor and compares the current signals to a normal operating range. The normal operating range may be predetermined or derived based on trends, thereby allowing the controller to adapt to any product disposed within the conduit. Once the range is determined, the controller is able to discern when the product system is out of product, or operating at elevated pressures. In alternative embodiments, a pumping device or an inductor may generate a recognizable wave pattern that may be monitored to determine if the product system contains product.
