Gas vortex flowmeter

The gas vortex flow meter is mainly used in industrial pipeline fluid flow measurement of the medium air, nitrogen, oxygen, hydrogen, methane, natural gas, steam and the like, almost no fluid density, pressure, temperature, viscosity when measuring actual volume flow rate The effect of the parameter. No moving mechanical parts, so high reliability and low maintenance. Instrument parameters can be stable over a long period of time. The gas vortex flowmeter uses a piezo-electric stress sensor , which has high reliability and can work in the operating temperature range of -20 °C to +250 °C. There are analog standard signal and digital pulse signal output . It is easy to use with digital systems such as computers . It is an advanced and ideal flow meter.

The pulse frequency signal output by the gas vortex flowmeter is not affected by changes in fluid properties and composition, that is, the meter factor is only related to the shape and size of the vortex generating body and the pipe within a certain Reynolds number range. However, as the flowmeter needs to detect the mass flow in the material balance and energy metering, the output signal of the flowmeter should monitor the volume flow and the fluid density at the same time, and the fluid properties and components have a direct impact on the flowmeter. The gas vortex flowmeter is a new type of flowmeter for measuring the fluid flow of a closed pipe according to the Karmen vortex principle. Because of its good media adaptability, it can directly measure the volumetric flow rate of steam, air, gas, water, and liquid without temperature and pressure compensation. With temperature and pressure sensors, it can measure standard volume flow and mass flow, which is throttling. Ideal alternative to flowmeters.

Gas vortex flowmeter To improve the gas's high temperature resistance and vibration resistance, our company recently developed a SYLUG modified vortex flow sensor. Due to its unique structure and material selection, the sensor can be used at high temperature ( 350 °C) and strong vibration. Use under harsh conditions (≤ 1g ). In practical applications, the large flow rate is often much lower than the upper limit of the instrument. With the change of the load, the small flow rate is often lower than the lower limit value of the instrument. The instrument does not work in its excellent work section, in order to solve this problem. The problem is usually used at the measurement site to reduce the diameter of the measurement to increase the flow rate, and use a smaller diameter instrument to facilitate the measurement of the instrument, but this reduction must be between the adjustable tube and the instrument has a length of more than 15D straight pipe Rectification makes processing and installation inconvenient. The LGZ adjustable-rectifier rectifier developed by our company has a circular arc shape , which has the multiple functions of rectifying, increasing the flow velocity and changing the flow velocity distribution. Its structure size is small, only 1/3 of the inner diameter of the process tube , and it is integrated with the vortex flowmeter. Not only does it not require the addition of a straight section of pipe, it can also reduce the requirement for the straight section of the process pipe and the installation is very convenient.
