Introduction to temperature pressure compensation integrated vortex street

The temperature pressure integrated vortex flowmeter concentrates temperature and pressure compensation in the vortex flowmeter, automatically detects the temperature and pressure of the medium in the pipeline, and automatically participates in the calculation of density, so that the displayed flow rate is more accurate. It can display the instantaneous mass flow rate and cumulative mass flow rate of the medium, as well as the temperature and pressure of the medium. It can measure liquids, general gases, saturated steam, superheated steam, etc.

2、 Characteristics:

1High measurement accuracy and wide range;

2Wide range of measuring media, capable of measuring liquids, gases, and vapors;

3The working temperature is high, and the medium temperature can reach 330 ℃;

4No moving parts, no wear and tear, high reliability;

5The body is made of stainless steel material, which is corrosion-resistant.

3、 Working principle:

When the fluid medium in the pipeline passes through the vortex generator (triangular column), a vortex phenomenon is generated due to local velocity acceleration. This vortex splits into two alternating columns, which are called Karman vortex streets.

The release frequency of Karman vortex street is related to the width size of the triangular column and the flow velocity of the fluid, but not to the characteristic parameters such as temperature and pressure of the medium.
