Precautions for the use of gas flow meters

Biogas is a mixture of gases, according to the fermentation raw materials and fermentation time, the composition of the gas is different, but its main components are methane and carbon dioxide.

There are many things that need to be paid attention to in the installation of gas turbine flowmeter, such as: the need for good grounding, the need to install filters during installation and the requirements of the installation environment, etc. Only when we really understand its installation precautions, can we effectively ensure the measurement accuracy and service life of gas turbine flowmeter.

The selection of gas turbine flowmeter can be considered from the following aspects:

Gas turbine flowmeter is a gas medium measurement instrument especially common in industrial production, its working principle is: the measured gas entering the flowmeter, accelerated by the deflector frame of cross-section shrinkage, through the inlet channel acting on the turbine blade, driving the impeller rotation. The impeller shaft is installed on the rolling bearing, and the number of impeller revolutions proportional to the volume of the measured gas is transmitted to the counter or flow computer after multiple decelerations to display the volume of the measured gas under actual conditions. In order to keep the instrument in a normal and stable working state, attention should be paid not only to the initial selection, but also to the correct and standardized operation in the subsequent installation and maintenance operations.

Turbine flowmeter interference fault phenomenon, fault causes and elimination methods

In order to ensure the long-term normal operation of the gas turbine flowmeter, it is necessary to check the operation status of the turbine flowmeter frequently, do maintenance work, and eliminate problems in time.

Biogas is a mixture of gases, according to the fermentation raw materials and fermentation time, the composition of the gas is different, but its main components are methane and carbon dioxide. In the normal stable gas production stage, methane accounts for 45% to 60% of the total gas volume, carbon dioxide accounts for 35% to 45%, and also contains a small amount of water vapor, hydrogen sulfide, hydrogen, carbon monoxide, ammonia, hydrocarbons, nitrogen, oxygen and methylmercaptan, in addition to containing a small amount of granular impurities.

Gas flowmeter has the characteristics of high measurement accuracy, wide range, low power consumption, easy installation, simple operation, can measure the working condition volume flow or standard volume flow, in the industrial installation process can be installed horizontally, can also be installed vertically, so it is widely used in various fields of industrial production.

The selection of gas turbine flow meter should be considered from the following aspects:

Turbine flowmeter has become one of the indispensable measuring instruments, turbine flowmeter selection, need to pay attention to the following points.

In order to ensure the long-term normal operation of the gas turbine flowmeter, it is necessary to check the running status of the flowmeter frequently, do maintenance work, and eliminate problems in time.

Gas turbine flowmeter common problem solution

In the purchase of gas flow timing, users often only pay attention to the caliber, temperature, pressure, flow and other necessary parameters, rarely to measure the medium to further understand, which undoubtedly increases the difficulty of the selection of gas flow meters, once the selection of incorrect meters measurement accuracy will be greatly affected.

The selection of gas turbine flowmeter should be considered from the following aspects:

Nominal diameter: DN50-DN400
Functional application: Mainly used for trade settlement, mobile prepaid system, remote meter reading
Advantages and characteristics: Low starting flow, good repeatability, small pressure loss
Applicable medium: Natural gas, compressed air, nitrogen, etc
