　　Qingdao Hesheng Zhiyuan Automation System Co., LtdTSGD7006 flowmeter, integrated vortex flowmeter distribution and wholesaleSet up a vertical column in the measuring pipeline, and the fluid alternately generates regular vortices on both sides of the column. This type of vortex is also known as the Karman vortex street. concerningvortex flow meterThe measurement system in is introduced as follows:

　　The vortex flowmeter is mainly composed of sensors (with amplification plates inside), connecting rods, and vortex generator components (with triangular columns and probes inside),Anti vibration flange vortex flowmeterCan be used for measuring superheated steam, saturated steam, compressed air, and general gases. In this measurement system, the vortex flow sensor is installed on a vertical pipeline and sends a pulse signal corresponding to the high-pressure airflow to the intelligent flow integrator. The intelligent flow integrator adopts microcontroller technology, which can be used in conjunction withDigital vortex flowmeterOr orifice flowmeter for flow measurement, it has a fully Chinese LCD display screen, which can display various information such as instantaneous flow rate, instantaneous heat, cumulative flow rate, cumulative heat, vortex frequency, medium pressure and temperature, density, time and date. It also has rich functions such as small flow automatic compensation, power outage flow compensation, and automatic meter reading. Connecting temperature and pressure signals can also automatically perform temperature and pressure compensation. It converts the pulse signal from the vortex flowmeter into instantaneous flow rate and accumulates it for local display, and outputs a 4-20mA signal proportional to the instantaneous flow rate for easy connection with PLC or DCS. The Shanghai Institute of Metrology and Testing has developed detection components for high-temperature stress resistant vortex street flowmeters, and these research and development projects have achieved high-level results. Some domestic enterprises also have a special preference for vortex flowmeters. Through technology transfer or cooperative development, they have joined the development and production of vortex flowmeters. The lower limit flow rate of vortex flowmeters depends on the working density and viscosity of the medium, and their upper limit flow rate is generally not affected by the pressure and temperature of the medium. Therefore, determining the flow range only requires determining the actual available lower limit flow rate. After calculating the lower limit flow rate, check the flow range table to determine the corresponding caliber

　　When a triangular cylindrical vortex generator is set up in the fluid, regular vortices are alternately generated from both sides of the vortex generator, which are called Karman vortices. The vortex columns are asymmetrically arranged downstream of the vortex generator.TSGD7006 flowmeterIt is a volumetric flowmeter that measures the volumetric flow rate, standard condition volumetric flow rate, or mass flow rate of gases, vapors, or liquids based on the K á rm á n Vortex Street principle. And it can be used as a flow transmitter in automation control systems. Anti vibration air flow meter applies the principle of fluid oscillation to measure flow rate. When the fluid passes through the vortex flow transmitter 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 pulse signal output by the flow sensor directly corresponds to the vortex separation frequency and has high cumulative accuracy. However, pulse signals are easily affected by on-site frequency converters, electromagnetic signals, and other sources, resulting in fluctuating flow values and inaccurate readings, which can easily cause problems for both parties in trade. In practical applications, large flow rates are often much lower than the upper limit of the instrument, and with changes in load, small flow rates are often lower than the lower limit of the instrument. The instrument does not work in its working range. To solve this problem, it is usually necessary to reduce the diameter at the measuring point to increase the flow rate at the measuring point, and use smaller diameter instruments to facilitate the measurement of the instrument

　　The release frequency f of the Karman vortex street of TSGD7006 flowmeter is directly proportional to the flow velocity v, so the instantaneous flow rate can be calculated by measuring the release frequency of the Karman vortex street. Strouhal number is an important coefficient of vortex flowmeter. In the flat part of the curve where St ≈ 0.17, the release frequency of the vortex is proportional to the flow velocity, so the detection frequency f can be used to obtain the flow velocity v, and the volume flow rate can be calculated from v

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdTSGD7006 flowmeterPrecautions during installation:

　　When welding the flange of the digital anti vibration vortex flowmeter to the straight pipe section, the sensor cannot be welded together. During installation, the flow direction indicator of the sensor should be consistent with the fluid flow direction inside the pipeline.

　　Before installing the sensor, a sealing ring must be placed in the flange groove. The positions of pressure and temperature measurement points are as follows: the pressure measurement point is located 3-5 DN downstream of the sensor, and the temperature measurement point is located 5-8 DN downstream.

　　When measuring high-temperature media with a vortex flowmeter in an alkali plant, do not wrap the sensor connecting rod around it with insulation material.

　　The shielded cable connecting the sensor should be routed as far away as possible from strong electromagnetic fields. It is not allowed to be laid together with high-voltage cables. Shielded cables should be shortened as much as possible and should not be coiled to reduce distributed inductance. Large lengths should not exceed 100 meters.

　　Before installing the sensor on the Laiwu flowmeter, the pipeline must be cleaned. Remove impurities from the tube to avoid clogging the sensor after flow. The pipeline for measuring liquids must be filled with the measured liquid to prevent bubbles.

　　Lianyungang TSGD7006 flowmeter, integrated vortex flowmeter distribution and wholesale to avoid the direct impact of high temperature heat sources and radiation sources. If installation is necessary, insulation and ventilation measures must be taken, and the output frequency signal is not affected by fluid properties and component changes. That is, the instrument coefficient is only related to the shape and size of the vortex generator and pipeline within a certain Reynolds number range. K is not only related to the geometric dimensions of the vortex generator and pipeline, but also to. The Strouhal number is a dimensionless parameter that is related to the shape of the vortex generator and the Reynolds number. The vortex flowmeter sets a vertical column in the measuring pipeline, and the fluid alternately generates regular vortices on both sides of the column. This type of vortex is also known as the Karman vortex street
