About Manometer, AP-189A Professional Air Pressure
The origin of the differential pressure gauge can be traced back to the late 17th century. Scientists have found through experiments that the pressure of liquid or gas increases with the increase of depth or height, which laid the foundation for the later research on hydraulics and gas mechanics. Until the mid-19th century, a liquid level gauge based on pressure changes was invented, which provided a theoretical basis for the invention of the differential pressure gauge. Differential pressure gauges are used to measure pressure differences between two locations and are commonly used in the following applications: flow measurement, air quality monitoring, level measurement, gas thermometry, and HVAC system control.
