Dear teachers: Generally, the range of a pressure gauge should be selected to be 1.5–3 times the operating pressure. In which specification?

Specifications for the Selection and Design of Automated Instruments (HG/T 20507-2014) 5.2.8 The selection of the measurement range for pressure measuring instruments shall meet the following requirements: 1. When measuring a stable pressure, the normal operating pressure value should fall within the range of 1/3 to 2/3 of the instrument’s measurement range. 2. When measuring the pressure of a pulsating medium (such as the pressure at the outlet of pumps, compressors, and fans), the normal operating pressure should be within the range of 1/3 to 1/2 of the instrument’s measurement range.
