Gas turbine flow meters are an efficient and accurate flow measurement solution for a wide range of industrial applications. The following are the secrets of gas turbine flowmeter technology:
Working principle
The working principle of the gas turbine flowmeter is based on the proportional relationship between the turbine rotation speed and the gas flow rate. When the gas flows through the sensor of the turbine flow meter, the high-speed rotating turbine blade is affected by the gas and rotates, and the rotating speed of the turbine changes with the change of the gas flow rate. By measuring the rotating speed of the turbine, the flow rate of the gas can be calculated.
Technical characteristics
- High accuracy: Gas turbine flowmeters have high precision to ensure accurate measurement results in a variety of environmental conditions. The measurement accuracy can reach class 1.0 or higher, meeting the need for accurate flow measurement.
- Wide measuring range: The gas turbine flowmeter has a wide measuring range, which can adapt to the gas measurement needs of different flow ranges. Its flow range is usually wide, such as Qmin/Qmax=20:1, suitable for a variety of working conditions.
- Fast response: Gas turbine flowmeter can quickly respond to changes in gas flow, real-time monitoring of flow dynamics, and provide timely and accurate data support for flow control in the production process.
- Simple structure: The structure of the gas turbine flowmeter is relatively simple, fewer moving parts and easy to maintain. Its compact design, small size, light weight, easy to install and transport.
Application field
Gas turbine flowmeter is widely used in petroleum, chemical industry, natural gas, scientific research, textile, boiler and other fields. Especially in the measurement of natural gas, coal-to-gas, liquefied gas and other gases, gas turbine flowmeters play an important role. At the same time, it is also used to measure the flow of medium fluids in air, nitrogen, oxygen, hydrogen and other industrial pipelines.
Selection and installation
In the selection, it is necessary to consider the nature of the gas, flow range, accuracy requirements and use of the environment and other factors. At the same time, in order to ensure the long-term stable operation of the gas turbine flowmeter, the following points need to be noted when installing:
- The installation location should be convenient for maintenance, free from strong electromagnetic field interference, mechanical vibration and thermal radiation.
- The flow meter should be installed horizontally or vertically, and the direction of fluid flow should be consistent with the direction marked on the housing.
- The upstream of the flow meter should be guaranteed to have a long enough straight pipe section to ensure the stability of the fluid flow.
Maintenance and calibration
In order to ensure the measurement accuracy and prolong the service life of the gas turbine flowmeter, it is necessary to carry out regular maintenance and calibration. Specific maintenance measures include:
- Regularly check the running status of the turbine flowmeter, including bearing lubrication, blade wear, etc.
- Clean the turbine flow meter regularly to remove dirt and impurities attached to the turbine blades and sensors.
- The turbine flowmeter is calibrated regularly to ensure the accuracy of its measurement results. The calibration period should be determined according to the use and manufacturer’s recommendation.
In summary, the gas turbine flowmeter has become an indispensable flow measurement tool in many industrial fields due to its high precision, wide measuring range, fast response and simple structure. In terms of selection, installation, maintenance and calibration, a variety of factors need to be considered comprehensively to ensure its long-term stable and accurate operation.
