Modern compressed air flow meter advantages and diversification

The compressed air flow meter can be metered by a turbine flow meter, which not only has the characteristics of a conventional orifice plate, a target type, a vortex flow meter and the like, but also has a measurement accuracy comparable to that of a volumetric flow meter, and Unique anti-interference and anti-impurity performance, in addition to the flow metering problem that can be measured by conventional flow. Compressed air flow meters have been widely used in flow measurement in various fields such as metallurgy, petroleum, chemical, energy, food, and environmental protection. The instrument uses a capacitive force sensor, which is the key to the high precision and high stability of the new product. It is unmatched by the original strain gauge force sensor. Compressed air flowmeter not only has the characteristics of traditional orifice plate, target type, vortex flow and other flowmeters without moving parts, but also has the measurement accuracy comparable to volumetric flowmeter, combined with its unique anti-interference and anti-impurity performance. In addition to the ability to measure the flow rate that can be measured by conventional flow, especially in the case of small flow, high viscosity, easy to block, high temperature, strong corrosion, strong vibration and other difficult flow conditions, it has good adaptability.
Advantages and diversity of the instrument
Compressed air flow meter, also known as intelligent vortex flowmeter, is a new type of flowmeter developed by the principle of liquid vibration. It is widely used in the measurement of fluids in petroleum, chemical, metallurgy and papermaking industries. The flowmeter has no moving parts, high reliability, high precision and long life, and can accurately measure the instantaneous flow and accumulated flow of liquid in a wide flow range. It is not affected by the temperature, pressure, viscosity and composition of the medium, and is not blocked, not stuck, not easy to scale, high temperature, high pressure, safe and explosion-proof, suitable for harsh environments. The flow meter is divided into an integrated display and a remote display, and can output a pulse signal or a current signal to network with the microcomputer.
1. Simple and firm structure, no moving parts, high reliability and long-term operation is very reliable.
2, the installation is simple, maintenance is very convenient.
3. The detection sensor does not directly contact the measured medium, and the performance is stable and the service life is long.
4, the output is a pulse signal proportional to the flow, no zero drift, high precision.
5, the measurement range is wide, the range ratio can reach 1:10.
6. The pressure loss is small, the operating cost is low, and it is more energy-saving.
7. In a certain range of Reynolds number, the output signal frequency is not affected by the physical properties of the fluid and the composition changes. The meter factor is only related to the shape and size of the vortex generator. There is no need to compensate when measuring the volume flow of the fluid. There is no need to recalibrate the meter factor.
7, a wide range of applications: steam (saturated steam), gas (air, oxygen, nitrogen, gas, natural gas, gas, hydrogen, liquefied petroleum gas, hydrogen peroxide, flue gas, methane, butane, chlorine, gas , biogas, carbon dioxide, nitrogen, acetylene, phosgene, oxygen, compressed air, argon, toluene, benzene, xylene, hydrogen sulfide, sulfur dioxide, ammonia, steam, liquid and water, etc.), liquid (water, high temperature water) , oil, food liquid, chemical liquid, etc.), liquid, gas flow can be measured.
