A manometer is a device that measures pressure under atmospheric conditions and during the operation of compressor systems. Traditional sphygmomanometers employ mercury or aneroid manometers as their gauges; the electronic manometer is a substitute for these. With advancements in medical tech and the effort of making such devices commonly available, many products are out in the market that can serve as your perfect fit.

For example, the differential pressure meter also does the same work more or less. They are made to figure out changes in pressure, both positive and negative. Let’s dive deep into these matters and explore more about the differential pressure meter or more precisely electronic manometer.

The Work Process of Electronic Manometer

Digital manometers, also known as electronic manometers, do not use the hydrostatic balance of fluids to measure pressure. Instead, they have a pressure sensor, which is a device that can turn a recorded pressure level into an electrical signal whose characteristic value is proportional to, or a stand-in for, the magnitude of the pressure. When pressure is put on the elastic part of the sensor, it bends. This bend is then turned into a value of an electrical property that can be measured and matched to a pressure reading. Most pressure sensors in a differential pressure meter use one of three types:

1. When a strain gauge is bent, it changes its electrical resistance. This is how resistive sensors work.
2. Capacitive sensors rely on changes in the value of capacitance seen when the shape of a capacitor changes the distance between its two plates.
3. Inductive sensors change the linear motion of a ferromagnetic core that is connected to a coil or inductor by changing the shape of the elastic part. The caused emf and AC in the coil change because of this shift.

A Pirani gauge, thermocouple-type transducer, or ionization gauge are some of the additional pressure transducer forms used to take readings at extremely low pressures. The micromanometer is another name for a low-pressure manometer.

What Is A Micromanometer Then?

Instruments based on the manometer concept, the micromanometer is built to reduce the influence of capillary effects and meniscus reading mistakes. A fan’s ability to move air through an HVAC system’s ductwork depends on the fan’s static pressure. Simply visualizing the force needed to inflate a tire is a good analogy for understanding static pressure.

A micromanometer is a U-shaped gauge used to measure pressure, air velocity, airflow, and other similar variables. Small pressure changes in gas or liquid can be detected using this instrument. Laboratory secondary manometers are often calibrated using a Digital Micromanometer. But even in low-velocity atmospheric wind tunnels, intelligent gadgets are now being utilized in HVAC systems. Today in the market various micromanometer and also similar differential pressure meter is available that you can choose from.

Conclusion

The electronic manometer has taken the market by storm due to its many benefits over its analog predecessors, especially its convenience. Since they do not use non-metric fluids, they may be used on uneven ground without affecting the readings. Pressure may be measured pretty much everywhere using a digital manometer.
