Project Overview

What are the advantages of gas turbine flow meters? The gas turbine flowmeter is a new generation of high-precision and high-reliability gas precision metering instrument developed independently by absorbing the advanced technology of domestic and foreign flow meters through optimized design and integrating the theories of gas mechanics, fluid mechanics, electromagnetics and so on. It has excellent Excellent low-pressure and high-pressure metering performance, multiple signal output modes and low sensitivity to fluid disturbance. Gas turbine flow meters are widely used in the measurement of natural gas, coal gas, liquefied gas, light hydrocarbon gas and other gases.

In industrial production and scientific research activities, a variety of flow measurement instruments are used. Whether it is gas flow measurement or liquid flow measurement, a matching flow meter is required. Among them, gas turbine flowmeter is one of the commonly used flowmeter types. Gas turbine flow meters are widely used in liquid and gas flow measurement due to their advantages of high precision, special technology, repeatability and fast response speed. At present, a large number of electronic technologies are used in fluid measurement, but the gas turbine flowmeter relies on the rotation of turbine machinery for measurement. This gives many users the illusion that the turbine flowmeter is an outdated product. In fact, turbine flowmeters currently use a large number of international electronic equipment. The signal measurement and transmission part of the flowmeter uses electronic and digital technology. The measurement accuracy of the gas turbine flowmeter is also very worthy of recognition.

It is no exaggeration to say that the advantages of turbine flow meters are still the most popular flow meter design.

Gas turbine flowmeters were originally developed in the early 1960s as a critical flow measurement applicationSolutions for the aerospace industry. Many turbine flow meters are used to measure fuel flow in rocket engines at range. Turbine flow meters also help determine the performance characteristics of jet and piston engines. Turbine flow meters also have the ability to withstand high g-forces. Turbine flow meters play a key role in the development of advanced fighter jets and surveillance aircraft, helicopters, and drones and other high-tech fields. Various military and government agencies, as well as major aerospace manufacturers, utilize turbine flow meters as an integral part of their equipment test stands.

A gas turbine flow meter, due to its simple design, is a reliable volume sensor that provides a direct physical flow measurement that can be converted into a digital pulse output. However, with the addition of modern electronics, turbine flowmeters have become advanced flow sensors with greatly improved accuracy and range capabilities.

All turbine sensors, including those with axially mounted rotors, tangentially mounted "paddle wheel" rotors, and insertion probes, incorporate freely suspended rotors that are produced by flowing fluid (liquid or gas) through the table Body rotation. An external detection coil detects the frequency output produced by each rotor. The frequency is proportional to the velocity of the fluid, and because the flow path is fixed, the rotational speed of the turbine is a true representation of the volumetric rate of the flowing fluid through the flow meter. Either a magnetic or a modulated carrier (radio frequency) signal sensor can be used to detect the rotation of the turbine rotor and provide an electrical output proportional to the flow rate. The RF detection coil extends meters over the low flow range to eliminate rotor reluctance. This is particularly useful in the very low flow range where magnetic resistance has a significant influence on linearity. In many applications, the meter's output frequency is processed electronically, from basic amplifiers, indicators and totalizers, to more complex flow computers that compensate for all measurable parameters and provide optimal volumetric or mass flow measurement accuracy.

Gas turbine flow meters remain a popular flow meter design due to their direct measurement technology, fast response, lightweight, compact size, rugged construction, inherent digital electronic output, cost advantages and accuracy . These characteristics have led to the use of cross-section turbine flowmeters in the industry. From measuring the flow of molten lead in car batteries, to metering power plants, to taking water from water level sight glasses to purify the air, to testing animals in space, to throttling bottom hydraulic lines, etc., turbine flowmeters are all examples of the excellence of turbine flowmeters.
