high temperature vortex flow meter

In industries such as petrochemicals, energy and power, and metallurgy, the flow measurement of high-temperature media (such as superheated steam, heat transfer oil, and high-temperature gas) has always been a technical challenge. Vortex flowmeters are widely popular due to their simple structure and high stability, but how do they perform in high-temperature environments? Can high-temperature probes ensure long-term reliable operation? This article will conduct an in-depth analysis from aspects such as principle, temperature resistance design and industry application.

1. Vibration effect

Compressed air is generated by air compressor or high pressure fan. When these devices are in operation, they all have varying degrees of vibration, and sometimes the vibration is relatively strong, and this vibration is transmitted through the connecting pipe. When selecting and determining the position of the vortex flowmeter, this influencing factor should be fully considered. In various detection methods, the anti-vibration performance of the instrument is not the same due to different detection components. For the vortex street of the detection element, the vibration resistance can reach 0.5~1G. When determining the installation position of the vortex flowmeter, it should be as far away from the power equipment such as air compressors and fans as possible.

The vortex flowmeter has a flow meter in the pipeline without output. The reasons for this failure and the corresponding solutions are as follows:

Vortex flowmeter has high requirements for installation and working environment, and the front and rear straight pipe sections must be installed in accordance with the specifications.
