Liquid-Filled vs. Dry Pressure Gauges: What's the difference? Published by: DirectMaterial. There are two main types of pressure gauges. Today, we will go over why you might consider investing in a liquid filled gauge vs a dry one. Dry pressure gauges are the work horse of the industrial and commercial parts world.

Look at most air compressors. Liquid-filled pressure gauges provide a number of advantages: The liquid absorbs the vibration and pressure peaks The liquid cushioning action allows the operator to take readings during dynamic load and rapid vibration conditions The liquid lubricates all moving elements, which drastically reduces wear and tear on movement Because most liquid-filled meters are filled with non-aqueous liquid and hermetically sealed, they operate in corrosive environments and are immune to moisture penetration and icing, and shock effects are reduced.

Liquid-filled gauges enhance the reliability and integrity of the measuring system for long periods under extreme operating conditions.

How to choose right liquid for pressure gauges? Guidelines to help ensure that A fluid corresponds appropriately with an application are: If icing is a problem, use indicators filled with silicone oil or other comparable liquids.

They have low viscosity even at degrees C. If the system has electrical accessories such as contacts, use insulating oils, and If extreme temperature fluctuations are expected, use silicone oils The higher the viscosity of the liquid, the greater its buffer capacity.
