Summary of steam vortex flowmeter products

Steam vortex flowmeter (also known as vortex street flowmeter) is mainly used for measuring the flow of industrial pipeline media fluid, such as gases, liquids, vapors and other media. It is characterized by low pressure loss, wide range and high accuracy. It is almost not affected by parameters such as fluid density, pressure, temperature, viscosity and so on. There are no movable parts, so the reliability is high and the maintenance quantity is small. Instrument parameters can be stable for a long time. The vortex flowmeter adopts piezoelectric stress sensor, which has high reliability and can work in the working temperature range of -20 to +250 C. It has analog standard signal and digital pulse signal output. It is easy to match with computer and other digital systems. It is an advanced and ideal flow meter.

Two. Product principle of steam vortex flowmeter

In the fluid, a triangular columnar vortex generator is generated, and a regular vortex is generated alternately from both sides of the vortex generator. The vortex is called Carmen vortex. As shown in the right picture, the vortex is arranged asymmetrically in the downstream of the vortex generator 1.

Matters needing attention

Legend

1. installation of expansion pipe

For small diameter and large flow, it is necessary to expand the pipe and ensure that the front straight section of the flowmeter is more than 15D, and the straight pipe section is more than 5D.

2. installation of shrinkage tube

For large diameter and small flow, it is necessary to install the shrink tube while ensuring that the front straight section of the flowmeter is more than 15D, and the straight pipe section is more than 5D.

3. installation of elbow pipe

If the front end of the flowmeter has a 90 degree elbow or a T type joint, ensure that the straight straight section of the flowmeter is equal to or equal to 15D, and the straight pipe section is equal to or equal to 5D.

4. installation of two bends on the same plane.

If the front end of the flowmeter has two 90 degree elbows, ensure that the front straight section of the flowmeter is more than 20D, and the straight pipe section is more than 5D.

5. installation of two curved pipes in different planes

If the front end of the flowmeter has two 90 degree elbows, ensure that the front straight section of the flowmeter is more than 25D, and the straight pipe section is more than 5D.

6. installation of regulating valve

If the regulator is needed before and after the flowmeter, ensure that the front straight section of the flowmeter is more than 25D, and the straight pipe section is more than 5D.
