Product Description
Vortex flow meter is one of the mainstream flow meters in the world at present, they are widely used in the petroleum, chemical, metallurgical, heating and other industries, measuring the flow rate of liquid, gas and steam.
A triangular prism-shaped vortex generator is set in the fluid. Reqular vortices are alternately generated from both sides of the vortex generator. These vortices are called Karman vortices, as shown in Figure 1. The vortex rows are asymmetrically arranged downstream of the vortex generator.
When a detection probe and the corresponding circuit are installed in the vortex generator, a vortex flow sensor is formed. The probe of the ATLU series vortex flow sensor adopts a special structure and material, and is an improved type of vortex flow sensor.

Model Selection
Selection Directions:
1. Measuring medium: Vortex flowmeter is a speed flowmeter, its principle, determines its measuring medium type, can be liquid, can also be gas or steam
2. Pipe diameter: Flange connected vortex flowmeter can be divided into pipe type and insert type installation according to the different installation methods
3. Measurement accuracy: The accuracy of the flange connected vortex flowmeter also has several grades, and it is divided according to the measurement medium. If it is to measure liquid, the measurement accuracy can reach 1.0%, and if it is to measure gas, the accuracy can reach 1.5%. If it is inserted vortex flowmeter, the accuracy can reach level 1.5% and 2.5%
4. Medium temperature: Generally speaking, it is divided into three ranges, which are divided into normal temperature, medium and high temperature
5. Nominal pressure: mainly divided according to the installation method, the main demand on the market is as follows: for example, flange clamp type (2.5MPa), flange connection type (1.0/1.6/2.5MPa), plug-in installation type (1.6MPa/2.5MPa/4.0MPa)
