i have seen in some pressure gauges that they are liquid filled ( there needles are submerged in liquid, perhaps in glycerine) , will some one tell me what are advantages of these liquid filled gauges over non filled gauges , are they are used for specific purpose or they can be used any where, and what liquids are used in filling these gauges?
thanks for giving me informations.
