Gas turbine metering performance characteristics

Gas Turbine Flow Meter is a combination of temperature, pressure, flow sensor and intelligent flow integrator, which has absorbed the advanced technology of domestic and foreign flow meters and optimized the design, integrated the theory of gas mechanics, fluid mechanics, and electromagnetics. A new generation of high-precision, high-reliability gas precision measuring instruments. The gas turbine flow meter is composed of a turbine flow sensor and an intelligent display. It has excellent low-voltage and high-voltage metering performance, and has a strong anti-interference ability and reliability of various signals. The output method, as well as low sensitivity to fluid disturbance, high accuracy, good repeatability, simple structure, less moving parts, high pressure resistance, wide measuring range, small volume, light weight, small pressure loss, convenient maintenance, etc.

Widely used in the measurement of natural gas, coal gas, liquefied gas, light hydrocarbon gas and other gases, gas turbine flow meter has a wide measurement range, the lower limit flow rate is less than 0.5m / s, the pressure loss is small, the impeller impact resistance is strong, with High anti-electromagnetic interference and anti-vibration capability, reliable performance, long working life, ultra-low power single-chip microcomputer technology, low power consumption, superior performance, the correction formula accuracy is better than ± 0.02%, the meter coefficient can be set online by key, and It can be displayed on the LCD screen. The LCD screen is intuitive and clear, with high reliability. The pressure compensation can be performed under the stable pressure condition of the measured gas. The EEPROM is used to protect the accumulated flow and the meter factor.

Protection time is more than 10 years, etc. Features: Gas Turbine Flow Meter is a dedicated type integrated rectifier in the inlet when the fluid flows into the flowmeter is rectified and accelerated, metal tube float flowmeter, turbine flowmeter, vortex flowmeter due to turbine The blade and the fluid are at an angle. At this time, the turbine generates a rotational force. After the friction torque and the fluid resistance are overcome, the turbine begins to rotate. Within a certain flow range, the angular speed of the turbine is proportional to the volume flow of the fluid. The magnetic induction principle uses a magneto-sensitive sensor to sense a pulse signal proportional to the volumetric flow of the fluid from a coaxially rotating signal wheel. The signal is amplified, filtered, and shaped to enter the flow of the smart flow integrator together with the temperature and pressure sensor signals. The processing unit performs arithmetic processing and displays the volumetric flow rate and total amount of gas directly on the LCD screen.
