What is the working principle of gas flow meter?

A triangular column-shaped vortex generator is set in the steam fluid, and regular vortices are alternately generated from both sides of the vortex generator. This kind of vortex is called Karman vortex, and the vortex columns are arranged asymmetrically downstream of the vortex generator. And the vortices are arranged asymmetrically downstream of the vortex generators. The gas flowmeter is a new type of flowmeter that measures the fluid flow in a closed pipeline based on the Karman vortex street principle. Due to its good medium adaptability, it can directly measure the volume flow of steam, air, gas, water and liquid under working conditions without temperature and pressure compensation. Equipped with temperature and pressure sensors, it measures volume flow and mass flow at standard temperature and pressure, making it an ideal replacement for throttling flow meters. In order to improve the high temperature resistance and anti-vibration performance of the gas flowmeter, our company has recently developed a new gas vortex flowmeter sensor. Due to its structure and material selection, the sensor can be used for high temperature (350°C) and strong vibration (≤1g) under harsh working conditions. In practical applications, the maximum flow is often far below the upper limit of the meter, and as the load changes, the minimum flow is often lower than the lower limit of the meter, so the meter does not work in its optimal working area. In order to solve this problem, the diameter of the measurement point is usually reduced to increase the flow rate of the measurement point, and a smaller caliber instrument is selected to facilitate the measurement of the instrument. However, this method of diameter reduction must have a straight pipe section with a length greater than 15D between the diameter reduction pipe and the instrument for rectification, which makes processing and installation inconvenient. For the convenience of use, the battery-powered on-site display gas flowmeter adopts high-tech technology of micro-power consumption. The lithium battery can work continuously for more than one year, saving the purchase and installation costs of cables and display instruments. It can display instantaneous flow and cumulative flow on-site. The temperature compensation integrated gas flow meter is also equipped with a temperature sensor, which can directly measure the temperature of saturated steam and calculate the pressure, so as to display the mass flow rate of saturated steam. The gas flow meter is equipped with temperature and pressure sensors, which can directly measure the temperature and pressure of the gas medium for gas flow measurement, thereby displaying the standard temperature and pressure volume flow of the gas.
