What is a variable flow meter?
Flow meter Variable surface is a specialized form of flow meter designed to determine gas or liquid pressure in the pipe system. They are commonly used in the scientific and industrial environment. There are two popular patterns that are used today, although they work in a very similar way. The narrow end of the cone is inserted into a pipe with a wide sealed end up. When the pipe is filled with liquid or gas, it enters the meter. The small bead inside the glass meter rises or falls with the pressure of pressure and the marking on the side of the glass allows you to get accurate reading. However, this meter has some disadvantages. It is somewhat large and it works through gravity, so the wide end must face accurate reading. Tentni always practical in a small or closed pipe system. Also, if the measured fluid leaves the remains on the glass, it will have to be replaced or cleaned.
If it is any of theThese problems, there are other recently invented versions of the variable surface meters. One type that can work in tight spaces and does not require gravity for reading is a correlated flow meter. To measure the amount of pressure in the tube, they use a magnetic ball and a spring. As the pressure increases, the ball is pushed on the spring. Then the spring expresses the amount of pressure it receives on the digital screen.
The disadvantage of the correlated version of the variable flow meter is that it is more difficult to read than the cone shape variety. Also, it does not use conventional measuring units on the display screen. After the correlated flow meter displays the number, the Must reader then use the graph to convert this number to metric or imperial measurement. Also, this system does not provide accurate values if the fluid temperature is too high or too low.
If the liquid to be measured may be damaged by one of the above meters, another type of flow meter can be usedAryic shoulder meter. These meters put the disc into the pipe flow. This disk is connected to a moving stem. The movements of the disk and the stem are scanned by the motion detector that measures and determines the pressure. The disadvantage is that the shoulder meter is more complicated than other types and requires greater maintenance.
Although each variable surface meter has disadvantages, they are also relatively simple, affordable and commonly used. More complex meters can be purchased at higher prices. The basis for all is the principle of providing slight resistance to flow in order to determine its strength.
