Product Details

1、 Overview of Steam Vortex Flow Meter Products

Steam vortex flowmeter (also known as vortex flowmeter) is mainly used for flow measurement of industrial pipeline medium fluids, such as gas, liquid, steam and other media. Its characteristics are small pressure loss, large range, high accuracy, and almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring volumetric flow rate under working conditions. No movable mechanical parts, therefore high reliability and low maintenance. The instrument parameters can remain stable for a long time. The vortex flowmeter adopts a piezoelectric stress sensor with high reliability and can operate within a temperature range of -20 ℃ to+250 ℃. It has both analog standard signals and digital pulse signal outputs, making it easy to use in conjunction with digital systems such as computers. It is a relatively advanced and ideal flow meter.

2、 Product principle of steam vortex flowmeter

When a triangular cylindrical vortex generator is set up in the fluid, regular vortices are alternately generated from both sides of the vortex generator. This type of vortex is called a Karman vortex, as shown in the right figure. The vortex columns are asymmetrically arranged downstream of the vortex generator, as shown in Figure 1.

Precautions

Legend

1. Installation of expansion pipe

For small diameters and large flow rates, it is necessary to expand the pipe installation and ensure that the front straight pipe section of the flowmeter is ≥ 15D and the rear straight pipe section is ≥ 5D

2. Installation of shrink tubing

For large caliber and small flow, it is necessary to install a reduction pipe, while ensuring that the front straight pipe section of the flowmeter is ≥ 15D and the rear straight pipe section is ≥ 5D

3. Installation of bent pipes

If the front end of the flowmeter has a 90 ° elbow or T-shaped joint, it is necessary to ensure that the front straight pipe section of the flowmeter is ≥ 15D and the rear straight pipe section is ≥ 5D

4. Installation of two bent pipes on the same plane

If there are two 90 ° elbows at the front end of the flowmeter, it is necessary to ensure that the front straight pipe section of the flowmeter is ≥ 20D and the rear straight pipe section is ≥ 5D

5. Installation of two curved pipes in different planes

If there are two 90 ° elbows at the front end of the flowmeter, it is necessary to ensure that the front straight pipe section of the flowmeter is ≥ 25D and the rear straight pipe section is ≥ 5D

6. Installation of regulating valve

If regulating valves need to be installed before and after the flowmeter, it is necessary to ensure that the front straight pipe section of the flowmeter is ≥ 25D and the rear straight pipe section is ≥ 5D
