Manometer

If you deal with liquids or gases in different industries, you will need different types of manometers. A manometer is a tool for measuring pressure and it is available in digital and analog forms. There are different types of manometers such as u-shaped manometers, hand manometers, tubular manometers, mercury manometers, etc.

Applications of manometer or pressure gauge

Manometers are used and play an important role in various fields in industries. Manometers measure and regulate both the pressure of liquids and the pressure of gases. Pressure gauges are also used in heating and ventilation devices.

Types of Hardex manometers

Hardex brand offers the most widely used manometers to the market. This tool is used in air cutting and welding industries to measure air pressure or other gases. In fact, all capsules that are used for air cutting or welding must be equipped with a manometer for safety. These manometers are:

  • Oxygen manometer

    The oxygen manometer is installed on the oxygen capsule and adjusts the oxygen gas output. This manometer is made of brass. Hardex has three models of oxygen manometers, codes OR01 and OR07 bear higher pressure than code OR02.

  • Carbon dioxide manometer

    The carbon dioxide manometer is installed on the carbon dioxide capsule and in addition to adjusting the pressure of the output gas, it also can withstand the high cold of this gas.

  • Argon manometer

    The argon gas manometer has a needle gauge and a flowmeter gauge and is used for argon welding and laboratory work.

  • Acetylene manometer

    The acetylene manometer is corrosion-resistant and left-round and has an internal protective layer.

Advantages and features of Hardex manometers

The Hardex brand has a variety of welding and air cutting manometers for different gases. This tool can also be installed in high pressure cylinders industrial. Hardex manometers are of high quality and what is important is that their body and internal parts are made of brass. Brass metal is made of copper and zinc alloys and is very hard and resistant to corrosion and rusting. The use of brass increases the user's safety. Hardex manometers, have good quality, and also a reasonable price.

Structure of manometers

The manometer has a tube that is open on one side and connected to the gas tank on the other side. In some manometers, a pressure gauge chamber is placed inside this tube, and the pressure gauge needle moves with the help of gearboxes in the chamber.

How the manometer works

Manometers have a tank containing a special liquid that is affected by the pressure force of gas or liquid and measures the force. Depending on the type of manometer and its shape, this amount of force can be adjusted.

Important factors in buying a manometer

When you want to buy a good manometer, you should pay attention to several points, which are:

  • The size of the manometer screen should be such that it can be seen from a relatively far distance and not be too big to be disturbing during installation.
  • The type of manometer is one of the factors that has a significant impact on the price of the manometer. The manometer must be made of materials that do not deteriorate in different environments and even toxic environments.
  • The measuring scale of the manometer is one of the things that should be considered when buying. Because manometers are based on pascal, bar, etc.
  • The connections of the manometer are one of the things that are important and these connections should not be too long or in such a way that it is difficult to read the numbers.
  • Measurement accuracy is one of the most important points that you should pay attention to.
  • Mark and brand of manometer

Manometer price + factors affecting it

The price of manometers is different according to their type and brand. The material of the parts and the body is also one of the factors affecting the price of the manometers. The Hardex brand has 3 models of manometers for oxygen gas, each of which is different from the other, and it also has special manometers for argon, co2 and acetylene gases. To buy the best welding manometer, you can visit Hardex shops across the country. It is also possible to buy Hardex tools online through online tool stores.

FAQ

1What is the difference between a manometer, flowmeter and barometer?
The difference between a manometer and a flowmeter is that the manometer is in terms of pressure, but the flowmeter is in terms of liters. In fact, the manometer shows the gas pressure, but the flowmeter shows the gas flow in liters per minute. A barometer is also a closed tube manometer.
