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. National Standard Specifications for Vortex Flowmeters

The national standard specifications for vortex flow meters mainly include the following items

1. GB/T 25922-2023 standard name: "Measurement of fluid flow in closed pipelines using vortex flow meters installed in circular cross-section pipelines filled with fluid". Issued by the State Administration for Market Regulation and the National Slag and Rock Standardization Management Committee. Centralized unit: China Machinery Industry Federation. Implementation date:

2. JB/T 9249-2015 Standard Name: What is the Failure of the Machinery Industry Recommended Standard Supervisory Department: Ministry of Industry and Information Technology/National Energy Administration Implementation Date: March 1, 2016 Remarks: This standard completely replaces JB/T 9249 - 1999， Belonging to industry recommended standards

3. JJF (Anhui) 179-2024 standard name: "Online Calibration Specification for Gas Vortex Flow Meter" Scope of application: Applicable to gas vortex flow meters with a diameter greater than DN50mm, used for measuring specific conditions of steam or other gas media, and able to directly display standard flow rate or mass flow rate. Remarks: Not applicable to vortex flow meters without temperature and pressure compensation. Other relevant standards include the International Electrotechnical Commissions IEC 60534 series, Chinas mandatory national standard GB/T 32201-201

5, and the National Metrological Verification Regulation JJG 198.

3. Is the gas mass flowmeter easy to use?

4. Range of vortex flowmeter

The core conclusion of the range of vortex flowmeter is that the applicable range of different media (gas, liquid, steam) varies significantly, and the selection should strictly match the characteristics of the media to ensure the lower limit of flow rate and installation conditions..

1. Gas measurement parameters In gas applications, the range ratio of vortex flowmeter can reach 1:30, but it must meet the requirement of flow velocity ≥ 4m/s. If the flow rate is lower t
