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. Kurz flowmeter parameter settings
The parameter settings of Kurz flowmeters (usually vortex type) need to be strictly customized according to the working conditions. The manufacturer usually completes basic calibration before leaving the factory, and users usually do not need to adjust them themselves. If you need to reset, be sure to operate under the guidance of professional personnel. 1. In the parameter menu, the preferred measurement medium (such as liquid, gas, steam) is set for the medium and compensation mode. The t
2. It is recommended to set the upper limit of the range selection at 1.2 times the maximum flow rate, and the minimum flow rate should not be lower than 10% of the full range. For example, when the actual flow range is 0.5-3m ³/h, if it is set to 0-10m ³/h, the low flow section may not be effectively detected. 3. Unit configuration flow units (such as m ³/h, L/min) and total units (such as liters, standard cubic meters) can be adjusted through password access to the parameter interface, which needs to be consistent with actual application requirements. Chongzhen or digital signals (RS485
5, MODBUS, etc.) need to be compatible with subsequent control systems
6 For gas or steam measurement, temperature and pressure compensation function should be enabled and real-time temperature and pressure values should be input to correct errors caused by density changes. If necessary, an external PID temperature and pressure compensation module can be added to improve stability. 7. Parameter matching and debugging. Vortex flowmeters are often used in conjunction with pressure transmitters, temperature transmitters, and secondary instruments. After installation, it is necessary to ensure that the range signals of all instruments match, and comprehensive debugging should be carried out according to the instructions. 8. Precautions for operation: Before adjusting parameters, read the instructions carefully and enter
