Abstract: A method to perform a pressurized test of a pressure retaining equipment is disclosed. The method includes inserting, via a nozzle of the pressure retaining equipment, a waterproof wireless sensor assembly into an enclosed volume of the pressure retaining equipment, closing, subsequent to said inserting, all openings of the pressure retaining equipment except a connection to a pump, applying, by the pump, pressure to a test fluid contained in the enclosed volume, wirelessly transmitting, by the wireless sensor assembly to a computing device external to the pressure retaining equipment, test readings, and analyzing, by the computing device, the test readings to determine a result of the pressurized test.

Abstract: A solar panel is electrically coupled to a battery and configured to convert solar energy to electricity to charge the battery. A heating element is electrically coupled to the battery. A thermal sensor is configured to detect an ambient temperature. The thermal sensor is configured to produce a temperature stream indicative of the detected ambient temperature.

Abstract: A pipeline pressure test that accounts for measurement uncertainties includes a method for performing a pressure test of a pipe section of a pipeline including receiving a desired pressure to be applied to the pipe section and a duration of time the desired pressure is to be applied to the pipe section, receiving a pressure measurement of a fluid, a temperature measurement of the fluid, a volume measurement of the fluid, and a pipe section strain measurement, determining a change in fluid pressure and a volume change, determining a pressure change uncertainty and a volume change uncertainty, checking that the pressure change uncertainty is within a pressure uncertainty threshold and that the volume change uncertainty is within a volume uncertainty threshold, determining whether the desired pressure has been applied to the inner surface of the pipe section for the duration of time; and outputting a result of the testing.
