  Why is the pressure gauge filled with liquid?

  Therefore, you have determined the scale and connection size required on the meter that is suitable for your application. You even know your preference for wetted materials. But, let the meter dry or be full of liquid? What are the benefits of Glycerine filled pressure gauge? Are there any negative effects? Believe it or not, determining this feature may confuse many customers.

  In short, Glycerine filled pressure gauge is strictly used as an inexpensive way to stabilize the needle and lubricate the inside of the pressure gauge during vibration applications. The most commonly used filling fluids are glycerin and silica gel. Glycerin is used in approximately 95% of all liquid filling applications and is usually "standard". The reason for using these liquids is that they are more viscous and their thickness helps keep the needle stable. Some meters dry out, but you can simply fill the sealed meter housing through the filling port (usually at the top), and then reinsert the filling plug when you are done.

  As with any decision, you should weigh the pros and cons when deciding what is right for you.
