What are the advantages of installing a liquid filled gauge?

Liquid-filled pressure gauges provide a number of advantages:

• The liquid absorbs vibration and pressure spikes.
• The dampening action of the liquid enables the operator to take readings during conditions of rapid dynamic loading and vibration.
  
  
• The liquid lubricates all moving elements, dramatically reducing wear from movement.
• Because most liquid-filled gauges are filled with non-aqueous liquid and are hermetically sealed, they perform in corrosive environments and are immune to moisture penetration and icing.
