Abstract

A high pressure dynamic micro differential pressure gauge, and methods for using and checking the same. The high pressure dynamic micro differential pressure gauge comprises a set of vertical manometer tubes in communication with each other, where one or more manometer tubes are connected to a resistance meter through signal lines, and the resistance meter is connected to a data collection and processing control system. Each manometer tube is full of low conductivity buffer liquid and high conductivity manometric liquid. The resistance meter is configured to measure resistances in the one or more manometer tubes, and the data collection and processing control system is configured to convert the resistances measured by the resistance meter into a differential pressure.
