What Are Gas Turbine Flow Meter?

When the fluid flows into the Gas Turbine Flow Meter, it is rectified and accelerated under the action of a dedicated integrated rectifier for the air inlet. Since the turbine blades are at a certain angle to the fluid flow direction, the angular velocity of the turbine is proportional to the fluid volume flow at this time.

According to the principle of electromagnetic induction, a magnetic sensor is used to induce a pulse signal proportional to the volume flow of the fluid from the coaxial rotating signal wheel. The signal is amplified, filtered, and reshaped and enters the intelligent flow totalizer together with the temperature and pressure sensor signals. The micro-processing unit of the instrument performs arithmetic processing. The volume flow and total flow of the gas are directly displayed on the LCD screen.

Please see the structure diagram below for the structure principle of Gas Turbine Flow Meter.

 structure principle of Gas Turbine Flow Meter.

Gas turbine flow meter working principle

The gas turbine flowmeter uses a turbine for measurement. It first converts the flow rate into the rotational speed of the turbine, and then converts the rotational speed into an electrical signal proportional to the flow rate.

Gas turbine flowmeter is used to detect instantaneous flow and total integrated flow. Its output signal is frequency, which is easy to digitize.

The induction coil and the permanent magnet are fixed on the housing together. When the ferromagnetic turbine blade passes the magnet, the reluctance of the magnetic circuit changes, thereby generating an induction signal.

The signal is amplified and reshaped by the amplifier and sent to the counter or frequency meter. The total accumulated flow is displayed. At the same time, the pulse frequency undergoes frequency-voltage conversion to indicate instantaneous flow.

The speed of the impeller is proportional to the flow, and the number of revolutions of the impeller is proportional to the total amount of flow. The output of the turbine flowmeter is a frequency modulated signal. It not only improves the anti-interference of the detection circuit, but also simplifies the flow detection system.

The gas turbine flowmeter has a turndown ratio of up to 10:1, and the accuracy is within ±0.2%. The time constant of the turbine flowmeter with small inertia and small size can reach 0.01 second.

Gas turbine flow meters Applications

Gas turbine flowmeters are mainly used for gas flow measurement in industrial pipelines.

Flow measurement of air, nitrogen, oxygen, hydrogen and other media fluids.

When measuring the volume flow under working conditions, it is hardly affected by the fluid density, pressure, temperature, viscosity and other parameters.

Natural gas turbine flow meter

The gas turbine flowmeter has the characteristics of high sensitivity, good repeatability, large range ratio and high precision. Therefore, it is widely used in natural gas flow measurement.

When the flow rate changes greatly, the gas turbine flowmeter is more suitable than the differential pressure flowmeter.
The gas turbine flowmeter has a wide range ratio, medium and large diameters can reach 40:1 to 10:1, and small diameters are 6:1 or 5:1.

With the development of natural gas measurement technology and the increasing requirements for natural gas trade and transfer measurement, gas turbine flowmeters can not only meet the requirements of trade measurement, but also meet a wide measurement range.

In addition, its equipment cost is lower than orifice flow meters and gas ultrasonic flow meters.
Therefore, gas turbine flow meters are being used more and more widely. Especially China’s natural gas market usage has increased significantly. However, it is common in the downstream market that the initial consumption of natural gas pipelines is low. Large supply. Turbine flowmeter can reduce the diameter of the measuring tube due to its wider range ratio, thereby reducing investment.

The gas turbine flowmeter has high accuracy. The accuracy of ordinary flowmeters is (±1~±1.5)%, and the special type is (±0.5~±0.2)%. However, the higher the accuracy, the more demanding on-site conditions. harsh. Turbine flowmeter has good repeatability. Short-term repeatability can reach (0.05~0.2)%. If you calibrate regularly, you can get high accuracy.

The gas turbine flowmeter has a compact and light structure, convenient installation and maintenance, and large flow capacity. It is suitable for high pressure measurement.

There is no need to open holes on the meter body, and it is easy to make a high-pressure meter, which can meet the pressure increase requirements of the pipeline. Because of the above advantages, it is one of the preferred flow meters in natural gas trade settlement.
