Main Types of Digital Manometers
The three main types of digital manometers—gauge, absolute, and differential—each serve specific purposes and have distinct characteristics. Digital manometers are highly valued for measuring differential pressure in HVAC systems and other applications. Understanding these types is crucial for selecting the right digital absolute pressure gauge for your needs. Let’s check these types!
Gauge Manometers
Digital absolute pressure gauge is designed to measure pressure relative to the ambient atmospheric pressure. They provide readings that reflect the pressure difference between the measured system and the surrounding environment. People commonly use this type of manometer in applications where only the relative pressure is of interest, such as monitoring the pressure of gases and liquids within systems open to the atmosphere.
Absolute Manometers
Such manometers measure pressure relative to a perfect vacuum, considered zero pressure. Unlike gauge manometers, which compare pressure to atmospheric pressure, an absolute pressure manometer provides a reading that reflects the total pressure exerted by a gas or liquid in a vacuum. This type of manometer is essential in applications where precise pressure measurements are needed, regardless of atmospheric changes.
For example, we offer our Digital Absolute Pressure Manometer, which provides a safe, accurate, and environmentally friendly method for measuring vacuum levels in various laboratory applications. Complying with ASTM D2041 and AASHTO T 209 standards, it accurately measures the specific gravity and density of asphalt mixtures.
Differential Manometers
These pressure manometers measure the difference in pressure between two points within a system. They are used when the pressure differential across a component or between two separate points in a process needs to be known. This type of manometer is beneficial for applications involving flow measurement and pressure drop analysis.
How to Use a Digital Manometers?
