Differential Pressure Gauge

Our range of differential pressure gauge has earned a high reputation in industries such as offshore oil engineering, chemical, power generation, mechanical and metallurgy.

Used to measure the pressure difference between two measuring points, this mechanical pressure gauge supports direct indication of the pressure difference on its dial plate.

Model Selection Guides
Static pressure refers to the designed pressure of pipeline on measuring points, and it is one of the necessary data that needed for pressure gauge selection. Measuring range is another important data.

To select a proper type f pressure gauge, it is important to know the proportional relationship between measuring range and static pressure.
