Wedge flowmeter

Overview

A wedge flowmeter is a V-shaped throttling element with its smooth top angle facing downwards, which facilitates the smooth passage of liquids or viscous liquids containing suspended particles without causing stagnation upstream of the throttling element. Can be used for flow measurement of viscous liquids, with viscosity up to 500mPa? S， Such as fuel, residue oil, heavy oil, it can also be used for flow measurement of liquid-solid mixtures containing suspended particles, such as slurry fluids, sewage, etc. It can also be used for flow measurement of media such as gas and steam.

Wedge flowmeter is a new type of flowmeter that began to gradually move towards practicality in the 1980s. Its detection component is a V-shaped wedge block (also known as a wedge-shaped throttling element), with its smooth top angle facing downwards, which is conducive to the smooth passage of liquids or viscous liquids containing suspended particles, without causing stagnation on the upstream side of the throttling element. Therefore, it is particularly suitable for measuring volumetric and mass flow rates in industries such as petroleum and chemical. Wedge flowmeter, also known as double flange pressure wedge flowmeter, pipe connected pressure wedge flowmeter, etc.

Wedge flowmeter Features:

1. Good repeatability and high accuracy, the calibrated wedge flowmeter has an accuracy of 0.5 level.

2. It has self-cleaning ability and no stagnant area.

3. Wear resistant, long lifespan, and high reliability.

4 * The pressure loss is smaller than that of the orifice plate.

5-type structure, on-site installation does not require the installation of pressure pipelines, and can be directly connected to the pipeline with threads or flanges. Construction is time-saving, labor-saving, and easy to maintain.

Parameter indicators of wedge flowmeter

1. Nominal diameter: 25mm ≤ DN ≤ 500mm
2. Reynolds number range: ReDzui can reach as low as 300 and as high as 106 or above
3. Nominal pressure: PN ≤ 10MPa
4. Working temperature: t ≤ 350 ℃
5. Accuracy: Level 1
Flow equation:

Wedge flow meters are generally integrated with differential pressure transmitters with remote transmission boxes, and the measured medium is isolated from the impulse line and transmitter, so they can be used for measuring dirty media. The structure is shown in the following figure:
