    Q1: What is the function of digital differential pressure manometer?
    A1: The function of a digital differential pressure manometer is to measure the pressure of a fluid, typically in a closed system. It can be used to monitor and control pressure levels in various applications, such as in industrial processes, HVAC systems, and medical equipment. Manometers are designed to provide accurate and precise pressure readings, allowing for proper maintenance and troubleshooting of systems.

    Q2: What is the sensitivity of a digital pressure manometer?
    A2: The sensitivity of a digital pressure manometer refers to its ability to detect small changes in pressure. It's typically measured in terms of the amount of deflection or movement of the manometer fluid (e.g., liquid column) in response to a change in pressure.

    A highly sensitive manometer will show noticeable deflection even with small changes in pressure, while a less sensitive one will require larger pressure changes to produce the same deflection. Sensitivity is influenced by factors such as the diameter of the tubing, the density of the manometer fluid, and the scale markings on the manometer.

    Q3: Why is mercury used in a manometer instead of water?
    A3: Mercury is used in manometers instead of water due to its higher density, which allows for more accurate measurements of higher pressures. Additionally, mercury's incompressibility and temperature stability make it suitable for various environmental conditions. However, mercury's toxicity has led to increasing concerns, prompting the exploration of alternative fluids in manometers, especially in applications prioritizing safety and environmental protection.

    Tips: How does a manometer work?

    The working principle of a manometer is based on the displacement of a liquid when subjected to pressure. Typically consisting of a sealed U-shaped or straight tube filled with liquid (such as water or mercury), a manometer operates by measuring the displacement of the liquid column in response to the applied pressure.

    The magnitude of the pressure is determined by measuring the height difference of the liquid column. Usually, a reference point (such as atmospheric pressure) is used as the zero point of pressure, and the change in height of the liquid column under the applied pressure relative to this reference point is measured.

    Specifically, when the pressure being measured is applied to one side of the manometer, the liquid in the tube moves, causing the liquid level on that side to rise while the level on the other side falls. By measuring the difference in height between the two liquid levels, the pressure can be determined.

    The working principle of a manometer may vary depending on its type and application, but the basic principle involves using the displacement of a liquid under pressure to measure pressure.
