Product details
Intelligent gas turbine flowmeter is an instrument used to measure gas flow rate, which determines the gas flow rate by measuring the rotational speed of the turbine rotating inside the pipeline. This device usually has the characteristics of high precision, good linearity, high stability, and the ability to adapt to various gas characteristics. In addition, intelligent gas turbine flow meters also have functions such as data acquisition, processing, storage, and remote monitoring, which can be widely used for gas flow measurement and control in fields such as natural gas, petrochemicals, metallurgy, and power.
The intelligent gas turbine flowmeter adopts the LWGY series turbine flow sensor (hereinafter referred to as the sensor) based on the principle of torque balance, which belongs to the velocity flow instrument. Sensors have the characteristics of simple structure, lightweight, high accuracy, good repeatability, sensitive response, and easy installation, maintenance, and use. They are widely used in industries such as petroleum, chemical, metallurgical, water supply, and papermaking, and are ideal instruments for flow measurement and energy conservation.
Sensors and display instruments are used in conjunction, suitable for measuring liquids in closed pipelines that do not corrode stainless steel 1Cr18Ni9Ti, 2Cr13, corundum Al2O3, hard alloys, and have no impurities such as fibers or particles. If matched with display instruments with special functions, quantitative control, over limit alarm, etc. can also be performed. The explosion-proof type (ExmIIT6) of this product can be used in environments with explosive hazards.
The sensor is suitable for media with viscosity less than 5 × 10-6m2/s at operating temperature. For liquids with viscosity greater than 5 × 10-6m2/s, the sensor needs to be calibrated with real liquid before use.
If users require special forms of sensors, they can negotiate to place an order. If explosion-proof sensors are needed, they should be explained in the order.
Introduction to Intelligent Gas Turbine Flow Meter
The ordinary alarm metal tube float flowmeter is a variable area flow meter based on float position measurement. Adopting an all metal structure and modular concept design, it is widely used in various industries for flow measurement and process control under complex and harsh environments, low flow rates, and various harsh medium conditions due to its small size, low pressure loss, large range ratio (10:1), and easy installation and maintenance.
The working principle of
The fluid flows through the sensor housing. Due to the angle between the blades of the impeller and the flow direction, the impulse of the fluid causes the blades to have a rotational torque. After overcoming the friction torque and fluid resistance, the blades rotate. After the torque is balanced, the speed is stable. Under certain conditions, the speed is proportional to the flow rate. Due to the magnetic conductivity of the blades, they are in the magnetic field of the signal detector (composed of magnetic steel and coils). The rotating blades cut the magnetic field lines and periodically change the magnetic flux of the coil, causing electrical pulse signals to be induced at both ends of the coil. This signal is amplified and shaped by an amplifier to form a continuous rectangular pulse wave with a certain amplitude, which can be transmitted to the display instrument remotely to display the instantaneous flow rate or total amount of the fluid. Within a certain flow range, the pulse frequency f is proportional to the instantaneous flow rate Q of the fluid flowing through the sensor, and the flow equation is:
In the formula:
F - Pulse frequency [Hz]
K - the instrument coefficient of the sensor [1/m3], given by the calibration sheet. If [1/L] is used as the unit
Q - Instantaneous flow rate of fluid (under working conditions) [m3/h]
3600- Conversion factor
The instrument coefficient of each sensor is filled in the certificate of conformity by the manufacturer, and the k value is set in the matching display instrument to display the instantaneous flow rate and cumulative total amount.
