The Boer equation requires that the measured fluid be an ideal fluid. This is simply impossible in practical applications. In many cases, the fluid distribution may be uneven, such as elbows, valves, reduced diameters, expanded diameters, pumps, tees, etc. For other meters, this is a difficult problem to solve. The V-cone flowmeter can evenly distribute the fluid under extremely harsh conditions. For example, there are single elbows and double elbows immediately upstream of the meter. After the cone “rectification”, the fluid distribution is more uniform to ensure that the meter can obtain under severe conditions. Higher measurement accuracy. Because the V-type flowmeter can evenly distribute the fluid curve, compared with other types of differential pressure flowmeters, the requirements for the upstream and downstream straight pipe sections are less. It is recommended to leave 0-3D straight pipe sections upstream during installation. , Leave a straight tube of 0-1D downstream. When the size of the user's pipeline is large, the price of the pipeline is high, or the straight pipe section is not enough, the V-cone flowmeter will be the best choice. 可在紧邻它的地方装有一个弯管或不在同一个平面上的双弯管而不会对测量精度有影响。 In the past ten years, tests have been carried out with a single elbow at 90 ° C or two double elbows that are not on the same plane upstream of the V-type flowmeter. Place a curved pipe or a double curved pipe that is not on the same plane without affecting the measurement accuracy. The boundary layer effect formed by the unique structure of the flow meter prevents the key parts of the throttle from being worn, so it can keep the geometric size unchanged for a long time, so it can work stably for a long time without calibration. The flow meter is a purely mechanical body, so it is resistant to high temperature, high pressure, corrosion and vibration. Wide range of measurable fluids (liquid, gas, steam), wide measurement range (small flow to large flow), applicable pipe diameters DN15 to DN3000.
，流量仪表系列，我公司液体技术人员在某安装工程中，对V锥流量计的安装方法给予下面的指导安装，给予客户参考：1.在安装前，必须检查流量计装箱清单，对照厂家计算书检查V锥流量计的开孔和差压变送器的量程，其次就是要保证现场直管段的长度。 Jiangsu Jinhu Dongxiang Instrument Co., Ltd. specializes in the production of V-cone flowmeters and flow meter series. In a certain installation project, our company's liquid technicians give the following instructions to the installation method of V-cone flowmeters for reference: Before installation, you must check the packing list of the flowmeter, check the opening of the V-cone flowmeter and the range of the differential pressure transmitter against the manufacturer's calculation book, and then ensure the length of the straight pipe section on site. 2. Proper use of gaskets, suitable specifications of screw nuts, spring pads, and symmetrical tightening force to ensure that the measurement condenser is installed at the same height. Note that the condenser cannot be installed at the lowest level of the V-cone flowmeter measurement system. Point to prevent measurement errors. 3. It can be installed horizontally, vertically or obliquely. The tube should be filled with medium fluid. The length of the pressure guiding tube is preferably within 16M. 4. It is better to install the temperature measuring element outside 10D on the downstream side of the throttle. When taking pressure on the pipeline or positive pressure pipe, if the pressure transmitter is installed below the throttle device, the pipe of the pressure transmitter must be installed. The liquid column value of the road is corrected to improve the measurement accuracy.
是一种创新性的差压测量装置，它通过悬挂在管线中心的一个Ｖ型锥体来节流，这样迫使流体以管线的中心线为中心，围绕着锥体流过。 The v-cone flowmeter is an innovative differential pressure measurement device. It is throttled by a V-shaped cone suspended from the center of the pipeline. This forces the fluid to flow around the center of the pipeline around the cone. Vortex flowmeter is an intelligent instrument used to measure the flow of liquids, gases and vapors in pipes. It is a new type of intelligent flow meter based on the Carmen vortex street principle. It has the function of on-site liquid crystal display, variable output current signal or frequency signal, and is matched with corresponding secondary meters or computer management systems. The flow meter is a three-phase flow meter with no radioactive source and multifunctional application in the actual field environment. It provides accurate, real-time measurement of oil / water / gas flow without separation, and low maintenance, which is easy to operate. This device does not require field calibration or prior knowledge of the characteristics of the media.
