The present invention is a contaminant removal device of a fluid pressure or flow measurement gauge used to remove internal residual contaminants (oil for calibrating an instrument) of a pressure gauge or a flow gauge, which are essentially provided in a high-pressure gas or liquid piping line. In more detail, the flow rate or pressure gauge is simply mounted on the removal device, and then the contaminants, especially the flammable oil, inside the gauge are reliably removed through cleaning and vacuum suction, thereby improving the operation of the device. The present invention relates to a contaminant removal device of a fluid pressure or flow measurement gauge that prevents a safety accident such as an explosion caused by flammable residual oil.

In general, the flow rate or pressure of a fluid in a high-pressure gas line, such as liquefied natural gas (LNG), city gas, or various types of high-pressure liquid (hereinafter, gas and liquid are collectively referred to as 'fluid') Gauges for measuring are provided.

For example, pressure measurement-related gauges for pressure control include a pressure controller, a digital pressure gauge, an analog pressure indicator, a pressure transmitter, and a dead weight tester (hereinafter, referred to as pressure measurement gauge).
