Pressure gauge – how to select

  To effectively select a pressure gauge, you need to consider the following: Gauge range The normal operating pressure should be confined to between 25% and 75% of the scale, if process pulsation is present then the maximum operating gauge pressure should not exceed 50% of the full-scale range.
