1. What is an intelligent vortex flowmeter?

Also known as Karman vortex street or Karman vortex, it is a physics theory proposed by Hungarian American aerodynamicist, Feng Karman, and also the doctoral supervisor of Qian Xuesen in China.. Vortex street refers to the phenomenon of unstable boundary layer separation that occurs in a fluid containing a blocking fluid under specific conditions. Two asymmetrically arranged vortices are generated on both sides downstream of the blocking fluid, with one vortex rotating clockwise and the other vortex rotating counterclockwise. The two rows of vortices are arranged in a staggered manner, similar to street lamps, hence the name vortex street. In daily life, when the river flows over obstacles, the Carmen Vortex Street is used. At the inlet of the flowmeter, a resistance fluid will be installed to generate a vortex street with high return. The vortex will impact the pendulum sensor behind the resistance fluid to record the frequency of the vortex. The higher the flow velocity, the higher the vortex street frequency. There is a specific relationship between fluid velocity and frequency, and flow meters obtain flow information through internal chip calculations. Li Chao

3. Intelligent Vortex Flow Meter Diameter and Flow Range

Instrument diameter and flow range are key parameters for selecting intelligent vortex flow meters.. Flow meters with different diameters have different measurement ranges and output frequency ranges. For example, for a 150mm caliber flowmeter, the measurement range for liquid gas and steam is from 3m/h to 636m/h, and the output frequency range is between 4Hz

and 446Hz; For larger 250mm apertures, the measurement range is extended to 65-1250m/h, and the output frequency range is 1.5-25Hz. The selection of these parameters needs to be determined according to actual application requirements. The application of intelligent vortex flowmeter in biogas pipelines requires special attention, as the flow rate of biogas pipelines is relatively small and usually requires reducing the diameter to ensure measurement accuracy. It is very important to choose a suitable Jiaoling flowmeter in biogas measurement. Firstly, it is necessary to understand the minimum flow rate, common flow rate, and maximum flow rate of biogas to ensure that the flow meter can effectively cover the measurement requirements. Meanwhile, as the biogas measurement site may not have a power source, a battery powered vortex flowmeter can be chosen to meet the on-site power supply conditions. If it is necessary to bring the display of the flowmeter indoors, an integrated vortex flowmeter can be selected, and the output signal can be transmitted to the indoor flow integrator through a cable to achieve on-site display. When installing a vortex flowmeter, special attention should be paid to the following points:

1. Avoid frequent opening and closing of valves near the upstream of the installation point to protect the service life of the sensor.

2. Try to avoid installing on very long overhead pipelines to prevent the sensor from sagging and causing seal leakage. If it must be installed on a long pipeline, a pipeline fastening device should be installed 2D upstream and downstream of the sensor. 3. Ensure that the fluid flow pattern at the inlet is not disturbed. The length of the upstream straight pipe section sh
