There are several industries operating worldwide that utilize liquid-filled gauges. The prime use of these gauges is to dampen the vibrations and pulsations. Since its name says liquid filled, this gauge remains intact because it is filled with glycerin mixed with water. Owing to the chemical composition of glycerin-water, it can work fine under ambient temperatures. This doesn’t throw a negative impact on recording the data. Under extreme temperatures, if the pressure gauge is not filled with water completely, the medium filled in the gauge absorbs the temperature and expands accordingly.
