Product Details

Eby-WQ050B4T1WY02 typeGas turbine flowmeterIt is a precision instrument based on the principle of moment of momentum to measure gas flow, widely used in the field of gas measurement such as natural gas, coal gas, compressed air, etc. It has become a key measuring equipment in industrial production and energy trade due to its high precision, wide range ratio, and fast response.

Structurally speaking,Gas turbine flowmetermainlyTurbine sensorandIntelligent display instrumentComposed of two parts. The core of a turbine sensor is a turbine impeller installed at the center of a pipeline, with specially designed blades at the edges of the impeller. When gas flows through the pipeline, it drives the impeller to rotate, and its speed is proportional to the gas flow rate. The rotation of the impeller is converted into an electrical pulse signal through magnetic electric induction or photoelectric conversion, and then processed by an intelligent display instrument to finally calculate the instantaneous flow rate and cumulative flow rate.

In terms of working principle,Gas turbine flowmeterUtilizing the law of fluid momentum transfer. When gas enters the sensor, it first passes through the front diffuser, allowing the airflow to smoothly impact the turbine blades and reduce the interference of eddy currents on the measurement. At the same time as the impeller rotates, the magnetic field inside the blade cutting sensor generates an electrical signal with a frequency proportional to the rotational speed. As the gas flow rate increases and the impeller speed increases, the pulse frequency generated also increases. Therefore, by measuring the pulse frequency, the gas flow rate can be accurately converted.

Gas turbine flowmeterofperformance advantageVery significant. Its measurement accuracy can reach ± 1.0%, and it can maintain stable measurement effect in a small flow range. The range ratio is usually 1:10 to 1:20, and some high-precision models can reach 1:40, which can meet the flow measurement needs under different working conditions. In addition, it has a fast response speed, can monitor flow changes in real time, and has low pressure loss, which has a low impact on the energy consumption of pipeline systems.

In terms of installation and maintenance,Gas turbine flowmeterThere are certain regulatory requirements. During installation, it is necessary to ensure smooth airflow inside the pipeline, and sufficient length of straight pipe sections should be set up in front and behind (usually the length of the front straight pipe section is 10 times the diameter of the pipeline, and the length of the rear straight pipe section is 5 times the diameter of the pipeline) to avoid turbulence caused by bends, valves, and other components affecting measurement accuracy. At the same time, it is necessary to stay away from strong magnetic fields and vibration sources to ensure the normal operation of the sensor. In daily maintenance, it is necessary to regularly check the connection lines of the instruments and the cleanliness of the sensors to prevent impurities from adhering to the impeller and affecting the speed.

It is worth noting that,Gas turbine flowmeterThe measurement results are affected by parameters such as gas temperature and pressure, so some models are equipped with temperature and pressure sensors that can be compensated in real time through intelligent instruments to further improve measurement accuracy. When selecting, it is necessary to comprehensively consider the properties of the gas being tested (such as corrosiveness, dust content), working pressure, temperature, and flow range, and choose suitable materials and specifications.

With the improvement of industrial automation level,Gas turbine flowmeterIt is developing towards intelligence and wireless direction, and some products have data storage, remote transmission, and self diagnosis functions, providing strong support for accurate measurement and efficient management of gas flow.
