👉 A gage fluid, also known as a gauge fluid or measurement fluid, is a specialized liquid used in precision measurement devices to facilitate the accurate reading of mechanical or physical parameters. It is typically colorless, non-toxic, and chemically inert, ensuring it does not interfere with the measurement process. Gage fluids are employed in various applications, including pressure gauges, flow meters, and temperature sensors, where they help to transmit and stabilize the measurement signal, enhancing the precision and reliability of the readings. By maintaining a consistent and stable medium, gage fluids ensure that the output signals accurately reflect the measured variables, crucial for maintaining high standards in industrial and scientific measurements.
