Principle of vortex flowmeter: By setting a triangular cylindrical vortex generator in the fluid, regular vortices are alternately generated from both sides of the vortex generator, which are called Karman vortices. The vortex flowmeter applies the principle of fluid oscillation to measure flow rate. When the fluid passes through the vortex flowmeter in the pipeline, two columns of vortices proportional to the flow velocity are alternately generated up and down behind the vortex generator in the triangular column. The release frequency of the vortices is related to the average velocity of the fluid flowing through the vortex generator and the characteristic width of the vortex generator. The integrated vortex flowmeter is a new type of flowmeter for measuring fluid flow in closed pipelines based on the Karman vortex principle. Due to its excellent medium adaptability, it can directly measure the volumetric flow rate of steam, air, gas, water, and liquid without temperature and pressure compensation. Equipped with temperature and pressure sensors, it can measure standard volumetric flow rate and mass flow rate, making it an ideal alternative to throttling flow meters. In order to improve the high temperature resistance and vibration resistance of vortex flow meters, our company has recently developed the HLUG improved vortex flow sensor. Due to its unique structure and material selection, the sensor can be used in harsh working conditions such as high temperature (350 ℃) and strong vibration (≤ 1g). In practical applications, the maximum flow rate is often much lower than the upper limit value of the instrument, and with changes in

load, the minimum flow disturbance often falls below the lower limit value of the instrument. The instrument is not working in its optimal working range. To solve this problem, it is usually used to reduce the diameter at the measuring point to increase the flow rate at the measuring point, and smaller diameter instruments are selected to facilitate the measurement of the instrument. However, this diameter changing method requires a straight pipe section of at least 15D in length between the reducer and the instrument for rectification, which makes processing and installation inconvenient. Our company has developed an LGZ variable diameter rectifier with a curved longitudinal section, which has multiple functions such as rectification, increasing flow velocity, and changing flow velocity distribution. Its structural size is small, only one-third of the inner diameter of the process pipe, and it is integrated with the vortex flowmeter. It not only does not require an additional straight pipe section, but also reduces the requirements for the straight pipe section of the process pipe, making installation very convenient. For the convenience of use, the battery powered local display vortex flowmeter adopts low-power high-tech. It can operate continuously for more than a year with lithium battery power supply, saving the procurement and installation costs of cables and display instruments. It can display instantaneous flow, cumulative flow, etc. on site. The temperature compensated integrated vortex flowmeter also comes with a temperature sensor, which can directly measure the temperature of saturated steam and calculate the pressure, thereby displaying the mass flow rate of saturated steam. The temperature pressure compens
