Glycerine-filled pressure gauge refers to the inside of a pressure gauge immersed in glycerin liquid. Glycerin has some advantages, such as protecting internal parts from corrosion. Glycerin filling also helps to reduce the influence of liquid and pipeline pulsation caused by pointer movement, making it easier to accurately read the pressure gauge. Finally, glycerin is filled with a lubricating aspect that helps keep the mechanical device (usually composed of gears and cogwheels) running smoothly. We can also use silicon as a fill fluid because some applications may be sensitive to the potential for glycerin contamination in the event of a catastrophic meter failure.

  Most of the pressure gauge manufacturer's liquid-filled level gauges can be supplied "dry" so that customers can fill them with their own liquids or use them directly without filling them. Therefore, the main pressure gauge design difference between a liquid-filled pressure gauge and an inexpensive and practical pressure gauge is the sealing method of the housing. Of course, there is a liquid filling

  The accuracy of the Glycerine-filled pressure gauge cannot be assumed to increase its accuracy just because of its accuracy, but, generally speaking, as the design complexity of the Glycerine-filled pressure gauge increases, the potential for improving internal components and accuracy also increases. Similarly, we provide highly accurate non-filled dry level gauges for applications where liquid filling needs to be considered. A good description of your application needs will enable us to choose the most suitable gauge for your application.
