A gas turbine flow meter places a turbine within the fluid being measured. When gas flows through the flow meter, it is rectified and accelerated by a specially structured rectifier. The impeller rotates due to the force exerted by the gas, causing periodic changes in the magnetic reluctance of the magnetic circuit caused by the impeller blades. Within a certain flow range, the angular velocity of the impeller is proportional to the flow rate. A pulse signal proportional to the fluid volumetric flow rate is induced using the principle of electromagnetic induction. This signal is amplified and shaped by a preamplifier, then integrated by a microcontroller and displayed on an LCD screen. Signals detected by temperature and pressure sensors are also input to the integrator for processing, yielding the standard flow rate, which is then displayed on the LCD screen.
Features
-
It has a wide measurement range, a lower limit flow velocity of less than 0.5 m/s, low pressure loss, and strong impeller impact resistance.
-
It has high resistance to electromagnetic interference and vibration, and adopts a fully sealed isolation protection for the self-lubricating shaft;
-
It features an internal oil reservoir, ensuring reliable performance and a long service life.
-
Adopting advanced ultra-low power single-chip microcomputer technology, the whole machine is powerful, low power consumption, and has superior performance. It is an intelligent flow display with non-linear accuracy compensation function.
-
The accuracy of the corrected formula is better than ±0.02%;
-
The instrument parameters can be set online via buttons and displayed on the LCD screen. The LCD screen is intuitive, clear, and highly reliable.
-
Pressure compensation can be performed when the pressure of the gas being measured is stable.
use
The gas turbine flow meter is a velocity-type instrument. It has advantages such as high accuracy, good repeatability, simple structure, wide measurement range, small size, light weight, low pressure loss, and convenient maintenance.
It can be widely used in industries such as petroleum, chemical, metallurgy, and urban gas pipeline networks. It is especially widely used in urban gas metering, transmission and distribution pipeline metering, and gas pressure regulating station metering.
