Liquid Filled Pressure Gauge Overview

A liquid filled pressure gauge is a type of pressure measuring device that contains a liquid, typically glycerin, inside the gauge to reduce the effect of vibration and pulsation on the pressure measurement. It is commonly used in applications where there are high pressure spikes or where accuracy is important, such as in hydraulic systems, boilers, and pipelines.

Benefits of a liquid filled pressure gauge include:

  • Increased accuracy: The liquid dampens the movement of the gauge's internal components, reducing the effects of vibration and pulsation on the pressure reading.
  • Improved stability: The liquid helps to stabilize the gauge and reduce the wear and tear on its internal components, increasing its lifespan.
  • Protection from corrosive environments: The liquid provides a barrier between the internal components and the environment, protecting the gauge from corrosive fluids and gases.

When using a liquid filled pressure gauge, it is important to select the correct liquid for the application, as different liquids have different properties that can affect the gauge's accuracy and performance. It is also important to properly install and maintain the gauge to ensure its accuracy and reliability.
