At present, compressed air flow meter products are widely used in metallurgy, petroleum, chemical, energy, food, environmental protection and other areas of the flow measurement. Compressed air flowmeters can be measured using turbine flowmeters, which not only have the characteristics of traditional orifice plate, target, vortex and other flowmeters without moving parts, but also have the same measurement accuracy as volumetric flowmeters, plus Its unique anti-jamming and anti-impurity performance, in addition to being able to replace conventional flow measurement can measure flow measurement problems, especially in small flow, high viscosity, easily congealed and easy to block, high temperature, strong corrosion, strong vibration and other difficult flow conditions It has very good adaptability.
Compressed air flow meter applications:
1. Measurement medium: gas, liquid, steam;
2. The double-row LCD displays the accumulated flow and instantaneous flow at the same time;
3, internal lithium battery power supply, no external power supply;
4, micro-power design, two +3v lithium battery can work more than a year and a half;
5. The sensing element of the air quality sensor is not directly in contact with the measured medium, and the performance is stable and reliable;
6. There are no movable parts in the sensor, the structure is simple and firm, the pressure loss is small, the dimension expansion is small, and the service life is long;
7. The range is as wide as 10:1~15:1.
Compressed air flow meter measurement features:
1, large vibration
Not every air flow meter is installed in a place with high vibration. However, the air flowmeter installed in the compression building and blower room must consider the vibration problem. This vibration mainly comes from the compressor and the blower. The vibration of the machine can be transmitted far away through air ducts or ducts.
2, gas with water
Compressed air is taken from the atmosphere, and the atmosphere always contains a certain amount of water vapor. The content of water vapor is expressed by the partial pressure ps of steam. The saturated partial pressure of water vapor in the atmosphere is a function of atmospheric temperature. In rainy and foggy days, the partial pressure of water vapour in the outdoor atmosphere reaches saturation, that is, the relative humidity reaches 100%. At this time, the atmosphere is compressed like a sponge that squeezes enough water. As the volume is reduced, there will be a corresponding amount. Water precipitated.
3, pulse flow
Most of the compressor and blower outlet fluid contain some pulsation. For example, a reciprocating compressor exhibits half-wave pulsation. Obvious swings in the outlet pressure of the compressor and the blower can be observed in the field. Among them, the positive (fixed) displacement blower outlet has a high pulsation frequency, which is generally several tens of Hertz, while the reciprocating compressor outlet has a low pulsation frequency, which is generally a few hertz.
Compressed air is an important secondary energy source for enterprises and institutions. Most of them are converted from electrical energy or heat energy through compressors. When the air pressure requirement is low, it is generated by a blower. The main purpose of the flow measurement of compressed air is to manage the working medium converted from a large amount of energy to receive energy conservation and improve the equipment management level.
