What are the advantages and disadvantages of a split type vortex flowmeter?

The advantages and disadvantages of a split type vortex flowmeter are as follows: Advantages: High precision measurement: Based on the mature Karman vortex principle, within the appropriate Reynolds number range, the measurement accuracy is high, generally reaching ± 1% R (R is the measurement value).. By accurately detecting the frequency of vortex shedding to calculate flow rate, accurate flow data can be provided when the fluid flow state is stable and within the designed measurement range. For example, in the meticulous batching process of chemical production, the flow rate of raw materials can be accurately controlled to ensure stable product quality. Wide range ratio: The range ratio can reach about 1:10-1:30, which can effectively work in a wide flow range and is practical for process flows with large flow changes. If the feed to the reaction kettle of a pharmaceutical company is small in the initial stage of the reaction and increases during the process, the vortex flowmeter can accurately measure the entire process without the need for frequent equipment replacement. Suitable for multiple fluids: can be used to measure various fluids such as liquids, gases, and vapors. Common industrial fluids such as water, oil, etc; Gases such as natural gas, compressed air, etc; Steam, whether saturated or superheated, can be measured as long as the parameters are within the allowable range of the equipment. It can play a role in multiple industries such as petrochemicals, electricity, food and beverage. Compact structure and flexible installation (relative): The sensor part is designed to be compact, making it easy to install in pipe

line systems. The split design allows sensors and converters to be flexibly arranged according to the actual situation on site. For example, in industrial plants with limited space, converters can be installed in locations that are easy to operate and observe, while sensors can be installed in suitable positions in pipelines. The two are connected by cables and are not strictly limited by distance. No moving parts (sensor part): There are no rotating parts inside the sensor, reducing the probability of failure caused by mechanical wear and improving equipment reliability and service life. At the same time, it avoids the interference of moving parts on fluid flow, making the measurement more stable. For example, in fluid measurements containing small particles, the measurement accuracy will not be affected by particle blockage of moving parts. Diverse output signals: It can output various signals, such as 4-20mA current signals, RS485 communication interface signals, etc. The 4-20mA current signal is convenient for connecting to various control systems, enabling long-distance transmission and strong anti-interference ability; The RS485 communication interface signal facilitates communication between multiple backup networks, enabling centralized data collection and management. It is very important in contemporary industrial automation systems and can be well coordinated with PLCs (programmable logic controllers), DCS (distributed control systems), and so on. Disadvantages are sensitive to fluid flow conditions: ideal fluid flow conditions are required, with stable velocity distribution and sufficiently long straight pipe sections. Generally, the length of the upstream straight pipe section is required to be at least 10-20
