Can vortex flow meters be installed vertically?

Project Overview

The vortex flowmeter is based on the Karman vortex principle. It has the advantages of no moving parts, simple structure, not easy to block, high temperature and high pressure resistance, etc. It is one of the most widely used flowmeters. In order to ensure the vortex flow For the measurement accuracy of the meter, correct installation is an important foundation. Vortex flowmeters can be installed vertically, but the following points need to be noted:

1. Installation direction

Depending on the actual installation situation, vortex flowmeters can be divided into horizontal and vertical types. Straight two ways.

1. The horizontal installation method means that the axis of the vortex flowmeter is parallel to the horizontal direction, and the rotation axis of the vortex is perpendicular to the horizontal plane. It is suitable for horizontal pipes or pipes with a certain inclination angle.

2. The vertical installation method means that the axis of the vortex flowmeter is parallel to the vertical direction, and the rotation axis of the vortex is parallel to the horizontal plane. It is suitable for vertical pipes or pipes with large inclination angles. .

II. Installation requirements

1. Straight pipe section requirements: The installation of vortex flowmeter has certain requirements for the upstream and downstream straight pipe sections of the pipeline. Generally, the straight pipe section requirements are the first 10D (D is the pipe diameter), followed by 5D. If the distance is not enough, it will affect the flow field of the medium in the pipeline, thus affecting the measurement accuracy of the instrument.

2. Avoid vibration: The vortex flowmeter should avoid being installed on pipes with strong mechanical vibration, because the vibration of the pipe will interfere with the measurement process of the vortex flowmeter and reduce the accuracy of the measurement results.

3. Installation height: The installation height of the vortex flowmeter should be selected according to the actual situation. The general requirement is that the height above the ground is more than 1.5 meters, and the installation location should be considered to facilitate reading and maintenance.

4. Avoid interference: Vortex flow meters should avoid installation in places with strong electromagnetic field interference, small space and inconvenient maintenance to ensure the accuracy and reliability of measurement data.

3. Other matters needing attention

1. When installing a vortex flowmeter, ensure that the distance between the sensor flange of the flowmeter and the pipe flange meets the installation requirements to ensure The sensor is able to correctly detect the flow in the pipe.

2. During installation, negative pressure should be avoided on the upstream side of the sensor to prevent air from entering the sensor and affecting the measurement accuracy.

3. During the installation process, attention should be paid to keeping the pipeline clean to prevent impurities and pollutants from entering the sensor and affecting the measurement results.

4. After the installation is completed, the vortex flowmeter should be debugged and calibrated to ensure the accuracy and reliability of the measurement data.

The vortex flowmeter is an instrument widely used in flow measurement. Using a vortex flowmeter with the correct installation direction can ensure the accuracy of the measurement results. When installing a vortex flowmeter, you should pay attention to the above points to ensure that the vortex flowmeter is installed in the correct direction and to ensure its performance and accuracy.
