Abstract
A pressure monitoring method comprising providing wellbore servicing equipment comprising a pump, a discharge flow path configured to discharge fluid from the pump, a discharge pressure monitoring system comprising a transducer in pressure communication with the discharge flow path, and an electronic circuit in electrical communication with the transducer and a monitoring system, collecting an electrical signal indicative of the pressure within the discharge flow path, processing the electrical signal to generate an upper pressure envelope signal, wherein the upper pressure envelope signal is representative of a high pressure within the discharge flow path over a predetermined duration of time, and comparing the upper pressure envelope signal to a predetermined upper threshold.
