Description

Wedge type flowmeter

Technical Field

The utility model relates to a wedge type flowmeter.

Background

The detecting piece of the wedge-type flowmeter is a V-shaped wedge block (also called a wedge-shaped throttling piece), and the vertex angle of the V-shaped wedge block is downward, so that the liquid containing suspended particles or viscous liquid can smoothly pass through the V-shaped wedge block, and stagnation can not be generated on the upstream side of the throttling piece. Therefore, the flow meter is particularly suitable for measuring the volume flow and the mass flow in the industries of petroleum, chemical engineering and the like.

The fluid is measured by a wedge-shaped flowmeter, because of the throttling action of the wedge, a differential pressure which is in a square relation with the flow value is generated on the upper and lower sides of the wedge, the differential pressure is led out from pressure taking ports on two sides of the wedge, and is transmitted to a differential pressure transmitter to be converted into an electric signal to be output, and then the flow value can be obtained after the calculation of a special intelligent flowmeter.

In a traditional wedge-type flowmeter, a pipe section is cut into a wedge shape, then the wedge is aligned with the pipe section, and then welding, pressure testing or nondestructive inspection is carried out. However, the strength of the pipe section is not good originally due to the installation structure, and the pipe section is easy to deform; meanwhile, after the pipe section is cut, the pipe section needs to be welded with the wedge block, the welding area is large, and the welding cost is increased.
