Before buying an air flow meter, the purchaser communicates with the technical staff of the flow meter manufacturer to provide the type of gas, the temperature and pressure of the gas, the size of the gas pipe, the user's steam consumption, the location of the pipe and the location of the gas meter. Wait, tell the flowmeter manufacturer to ensure that the gas flowmeter can meet the on-site measurement requirements.
The measurement of 　　 generally uses air flow meters. However, due to many factors in the measurement of gas metering in industrial production, measurement problems frequently occur. The gas measurement is a very critical link, which is related to the accounting of the production cost of the enterprise, so the accuracy is very important.
　　 In addition, the steam flowmeter should be protected after installation. Don't leave the air flowmeter in the wind and rain, and check the gas flowmeter regularly, and replace it in time when it expires.
When choosing an air flow meter to measure, you need to pay attention to what circumstances require that the gas flow meter can accurately measure, otherwise more or less measurement will bring losses to both parties; contract energy management is also commonly known as “contracted boilers, manufacturers buy gas; thermal power plants Gas metering is used internally; air flow meters are used in the factory. No matter what kind of need is
　　 Because the measurement results of air flow meters are generally used for trade settlement between the two parties, and the billing amount is relatively large, the quality of the gas flow meters is very important, and the installation process is very critical, which directly affects the settlement.
　　Secondly, if there is a situation that is not clear, the technicians of the gas meter manufacturer can go to the site to check, and when installing the flowmeter, find a professional person to install it.
Air flow meter is a kind of flow meter which is widely used. It can measure almost all the media flowing in the pipeline, including various gases, liquids and steam.

The vortex flowmeters produced by our company can be divided into the following categories:

Installation form: flange-mounted vortex flowmeter, flange connection vortex flowmeter, plug-in vortex flowmeter, special vortex flowmeter for oil field, welded vortex flowmeter


 LUGB series air flow meters are mainly used for the measurement of compressed air flow. The main purpose of using air flow meters is that compressed air is an important secondary energy source for enterprises and institutions, and most of them are converted from electrical or thermal energy through compressors. When the air pressure value is low, it is generated by the blower. Manage the working fluids converted from a large amount of energy in order to receive the effect of saving energy and improving the level of equipment management.
  In the chemical industry and other production processes, there is an important process oxidation reaction for air flow meters. It uses air as a raw material and chemically reacts with another raw material under specified conditions. Too large or too small air mass flow will have a critical impact on safe production, product quality and consumption of valuable raw materials. In this case, the air flow measurement requirements are particularly high, and most of them are equipped with automatic adjustment.
 The combustion process in air flow meter boilers and various industrial furnaces is essentially an oxidation reaction. Although the accuracy requirements for the measurement of combustion air flow are not as high as the oxidation reaction in chemical production, it is important for environmental protection and economic combustion. , Fuel saving is also of great significance.


The air flow meter is researched and produced according to the Karman vortex street principle, and is mainly used for the flow measurement of industrial pipeline fluids, such as gas, liquid, vapor and other media. It is characterized by small pressure loss, large measuring range, and high accuracy. It is hardly affected by fluid density, pressure, temperature, viscosity and other parameters when measuring volume flow under working conditions. There are no movable mechanical parts, so the reliability is high and the maintenance is small. The instrument parameters can be stable for a long time. The air flow meter adopts piezoelectric stress sensor, which has high reliability and can work in the working temperature range of -20℃～+250℃. It has analog standard signal and digital pulse signal output. It is easy to use with digital systems such as computers. It is a relatively advanced and ideal measuring instrument.
