Manometers

Hydraulic manometers

A manometer is a high-precision device, a mechanical or electrical manometer. The hydraulic manometer measures the pressure in the working fluid system, which can be oils, gases and water. Such a device works on the principle of the reaction of a liquid to a force applied on one side.

Types of hydromanometers

In general, pressure meters are divided into two groups:

• Radial. In such a meter, the scale is perpendicular to the ground, and the fitting – connection point with the – is at the bottom.
• Axial or axial. In them, the scale is parallel to the ground, and the fitting is located on the back side.

However, the location of the fitting does not affect the accuracy of measuring the pressure of gases, water and other liquids, as well as the range of atmospheres. At the same time, the placement of the fitting does not affect the type of working fluid the device can work with.

By design, manometers for hydraulics are of the following types:

• Hydraulic or fluid. They work due to the position of the fluid in the ring or arc. Both sides can be the same or one of them acts as a small reservoir. In the arc model, the system exerts pressure on one end of the arc while the other end of the hydrometer rises. An increase in pressure leads to a greater displacement of the fluid in the curved tube. Therefore, such a hydromanometer is also called a pipe one.
• Pistons. The main elements are a stock with loads – they bring the system into balance. This is the most accurate instrument for calibrating, grading and verifying manometers. The error is from 0.05% to 0.1%. Wide operating range, high measurement repeatability and stability – undeniable advantages of such a unit.
• Deformative. The principle of operation is based on the use of deformation of an elastic sensitive element. It occurs under the influence of pressure, which is measured. The value of this strain is then transmitted to a reading device in a device with calibrated pressure units.

Which manometer to buy for measuring pressure in a hydraulic system?

To make the right choice when buying a manometer, you need to consider the following parameters:

1. Scale value – pressure measuring range. To determine it, it is necessary that the working pressure in the system fluctuate in the scale interval from ⅓ to ⅔.
2. Accuracy class – error indicator. The lower the value, the smaller the error.
3. Size – manometer diameter.
4. Type of connection (radial or axial).
5. Degree of protection and case material. If the device will be used for domestic needs, there is no need for increased strength. For specific needs, the manufacturer's recommendations and operating conditions should be taken into account.
