What is the difference between a Glycerine filled pressure gauge and a dry pressure gauge?

　　Answer: Although dry pressure gauges are the most commonly used pressure gauges, they also have some disadvantages.

　　1. The dial may be blocked by moisture accumulated in the gauge.

　　2. The temperature drop may cause irreparable damage to the diaphragm, bellows, Bourdon tube, or piston of the sensor.

　　3. Pressure fluctuations may make it easier to burst the pressure gauge instantly.

　　So, what is the difference in the way the Glycerine filled pressure gauge works? Glycerine filled pressure gauge works the same as a dry gauge; however, the accuracy is usually higher. The Glycerine-filled pressure gauge has the same measuring range as the dry gauge, and sometimes even larger.

　　These meters have scales and glycerin-connected faces to reduce visibility problems in wet conditions and prevent pulsations and pressure spikes in the system. The fluid also reduces the effects of vibration and internal friction of moving parts.

　　Glycerin will help prevent internal corrosion of equipment by acting as a door to prevent moisture and other substances from entering
