  • Patent number: 11401929
    Abstract: A universal monitoring system applicable to a variety of hydraulic fracturing equipment includes an accelerometer mounted on a housing of a positive displacement pump and configured to sense a vibration associated with the positive displacement pump on start-up and generate a wake-up signal. A processor is communicatively coupled to the accelerometer and configured to initiate execution upon receiving the wake-up signal. A pressure strain gauge is mounted directly on the pump housing and is configured to sense deformity in the pump housing caused by alternating high and low pressures within the pump housing and generate sensor data. The processor is configured to receive the sensor data from the pressure strain gauge and configured to analyze the sensor data and determine a cycle count value for the positive displacement pump, and there is at least one communication interface coupled to the processor configured to transmit the sensor data and cycle count value to another device.
