This article will tell you what you need to know about manometers. If you read on, you will find out what a manometer is, what it measures, and how it works. You will also learn out about manometer types and models and get some pointers about finding the right device for your process. Don’t forget to check out our articles on digital manometers, on calibrating manometers, and how battery life influences the accuracy of digital manometers.

When we have to measure pressure, we have several ways to do it. However, “we” in this case can mean field technicians or your average citizen. You can find examples all over your daily life for measuring pressure.

Have you ever had to fill a car or bike tire?
Or have you ever had a medical checkup? For these purposes, you need to check pressure, air for your tires and blood for you. We can’t afford to have too much or too little pressure in any of these situations.

So we have many ways to measure pressure, both digitally and “analogically.” Yes, you’ll find digital pressure indicators outside of industrial processes too.

What is a manometer?

A manometer is a tool to measure pressure in closed systems. Manometers generally come in two types, liquid and elastic. These types in turn divide into several models:

  • U-tube manometer
  • Differential U-tube manometer
  • Inverted U-tube manometer
  • Inclined manometer
  • Bourdon pressure gauge
  • Aneroid gauges

Manometers measure different types of pressure, absolute, gauge, and differential. If you want to know more about those, then read our article on that here. You must know the right pressure to measure in order to pick the right manometer for your application.
