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； .....

3. What are the effects of applying for mandatory testing instead of going to another place for testing?
If a vortex flowmeter applies for mandatory testing but is not sent for testing according to regulations, but is tested by a non designated institution on its own, it will bring various adverse effects.
1. Legal Risks of Violating Metrology Regulations 1 Mandatory calibration of measuring instruments should be carried out by legal metrological calibration institutions or authorized
2. Loss of dust effectiveness in measurement data 1 Testing reports issued by non designated institutions are not recognized by regulatory authorities, and flow meter measurement data cannot be used as legal measurement vouchers. There may be loopholes in the internal measurement management system of the enterprise. When used for production process monitoring or energy measurement, flow meter data that has not been legally verified may have no guarantee of accuracy, which may lead to production parameter loss of control, energy statistics distortion, and affect enterprise operation decisions.
III. Difficulties in Subsequent Verification and Management 1 Due to failure to complete mandatory calibration as required, subsequent reapplication for statutory calibration may require additional fees, acceptance of rectification requirements, and even suspension of flow meter use until compliance is achieved. 2. If there are records of violations in the management files of enterprise measuring equipment, it may affect subsequent work such as recording and updating of measuring instruments, and increase management costs.
