Vortex flowmeter installation precautions

Vortex flowmeter is a widely used instrument. In practical applications, it is necessary to understand the use environment and installation requirements.

Precautions during installation

1. Avoid vibration

Vortex flowmeter must be installed in small vibration, shock environment. If there is vibration in the pipeline, measures such as strengthening the pipeline should be taken to reduce the vibration.

2. Heat insulation and ventilation

If the flow meter is subjected to strong thermal radiation from the equipment, heat insulation and ventilation measures should be taken.

3. Space

To ensure subsequent installation and maintenance, the installation site must have enough space near the device.

4. Installation direction

The flow meter can be installed vertically, horizontally or at an Angle. When measuring, the liquid must fill the measuring point; When installed vertically, the flow of liquid should be bottom-up.

5. Installation position

The flowmeter is usually installed downstream of the valve

6. Pipeline reservation

When installing the flowmeter, it is necessary to ensure that there is a long straight pipe section at the front and back of the flowmeter to ensure accuracy.

Problems to pay attention to when installing

When installing, you must pay attention to the direction and determine the installation direction according to the data requirements of the instrument.

The upper and downstream of the instrument need to have enough straight pipe sections, otherwise the equipment accuracy is reduced or even abnormal work.

In some special working conditions, it is necessary to calculate the temperature and pressure compensation of the measured medium, and the temperature and pressure compensation module can be installed.

It is necessary to pay attention to the phenomenon of vaporization of certain media due to reduced pressure when passing through the instrument.

Reduce the impact of vibration and shock on the equipment.

Improper installation of vortex flowmeters may lead to many problems such as no signal output, pseudo-output, intermittent or unstable output, inaccurate or nonlinear output, and non-repetitive output. However, if careful attention is paid to the installation, most problems can be avoided. As long as it is carefully observed and analyzed in practical application, problems can be found and solved to ensure normal use.
