Large scale customized quotation: The new DY150 vortex street flow brother bridge quantity meter (4-20mA output) requires a minimum of 100 units for batch, with a unit price range of 440-4400 yuan.

2. 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

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 is the difference between vortex flowmeter and electromagnetic flowmeter? There are significant differences between vortex flowmeters and electromagnetic flowmeters in terms of principles, measured substances, and application ranges. 1. Principle: A vortex flowmeter is based on inserting an object (such as a slug) into a fluid to generate a vortex, and calculating the flow rate by measuring the frequency of the vortex. The electromagnetic flowmeter is based on Faradays law of electromagnetic induction, which states that when a conductor moves in a magnetic field, an electromotive force is generated in the conductor, resulting in an electric current. In an electromagnetic flowmeter, the conductor is the fluid. When the fluid moves in a magnetic field, an electromotive force is
