What are the measurement ranges of vortex flowmeters?
1、 Vortex flowmeter is a flowmeter based on the Karman vortex principle for measurement. It can measure liquids and gases, and is also very economical. The diameter is generally DN10-- DN1000. With temperature and pressure compensation, it can accurately measure gas or steam flow, and has a wide range of applications;
2、 Vortex flowmeter can only measure volumetric flow rate, usually in m3/h (cubic meters per hour), with instantaneous flow display and cumulative flow display;
3、 The measurement range corresponding to electromagnetic flow meters of different diameters is: liquid measurement: (unit: m3/h): DN15
1.2-6; DN20
1.5---10； DN25：2---16； DN32
1.8---20； DN40：2.5---25； DN50：3.5---40； DN65：7.5---70； DN80：12---130； DN100：18---160； ..... Gas measurement: (unit: m3/h): DN15:4--28; DN20：6---40； DN25：8---50； DN32：15---150； DN40：18---180； DN50：25---480； DN65：50---500； DN80：80---800； DN100：120---1200； .....

2. Flow meter specifications and models
Common specifications and models of different types of flow meters are summarized as follows
1. Vortex flow meter models cover different media and flow scenarios, including FS series for industrial gas measurement and micro vortex flow meters for small flow detection
Conductive liquids such as media and mud, with specifications ranging from DN1mm to several meter caliber
4. Mass flow meters are based on HH For example, according to the nominal diameter of the pipeline,
6、DN
10、DN1
5、DN2
5、DN40、DN50、DN80、DN100（ Unit: mm) There are a total of 8 specifications for physical flow meters. Taking EXAIRs 9090 model as an example, it is compatible with 1/2 "to 8" Schedule 40 iron pipes and 25mm to 101mm aluminum pipes, and can support up to 4 "copper pipe air flow measurement. • Vortex/Swirl Vortex Flowmeters: including the conventional DN20-DN200 Swirl Vortex Flowmeters from Astra Instruments and the LUGB series from Chongqing Chuanyi. Ultrasonic flow meters: such as Emerson FLUXUS G721 CA clamp type, Astra ATLS clamp type, and other models.
3. Can vortex flowmeters be installed vertically?
Vortex flowmeters can be installed vertically, but some installation points need to be noted.
. Firstly, vortex flowmeters are feasible for vertical installation. However, in order to ensure the accuracy and stability of the measurement, special attention should be paid to the following points:1. Avoid the influence of sediment and bubbles: When installed vertically, ensure that there is no accumulation of sediment or bubbles inside the flowmeter, as these factors may interfere with the measurement accuracy of the flowmeter.
. Chenzai rubber residue may adhere to the measuring electrode of the flowmeter, causing signal distortion; Bubbles may generate false flow signals. 2. Keep the electrode axis horizontal: Although vortex flowmeters can be installed vertically, it is recommended to keep the measuring electrode axis horizontal to better avoid the influence of sediment and bubbles. This can minimize the interference of sediment and bubbles on the measuring electrode, thereby improving the accuracy of the measurement. Inte
