What interference will the vortex flowmeter suffer?

Fameter Vortex Flowmeter

1. Noise Interference

When the fluid passes through the pipeline, there is a relative motion between its speed and the flow rate, which will generate vortices. Therefore, the vortex flowmeter measures the flow rate by detecting the frequency of the vortex and calculating the flow rate of the fluid. However, in some environments, such as computer rooms, there may be loud noises, which will interfere with the vortex flowmeter and affect its measurement results.

Solution: When choosing a vortex flowmeter, you can consider choosing a model with anti-noise performance, or take sound insulation measures during use to reduce noise interference.

2. Vibration interference Vortex flow meters are usually installed on pipelines. If the pipeline is vibrated by external forces, pressure waves will be generated, causing errors in the flow meter.

Solution: When selecting and installing the vortex flowmeter, you need to pay attention to the stability of the pipeline, and install shock absorbers on both sides of the pipeline.

3. Temperature changes The measurement results of the vortex flowmeter are affected by temperature. When the ambient temperature changes greatly, the measurement accuracy of the vortex flowmeter will also be affected.

Solution: In the use of vortex flow meters, temperature compensation technology can be used to improve measurement accuracy, or temperature factors can be considered during the installation process according to specific circumstances.

4. Electromagnetic interference In some industrial environments, there is strong electromagnetic interference, which affects the measurement accuracy of the vortex flowmeter. Solution: When designing the vortex flowmeter circuit, electromagnetic interference suppression technology can be used, or anti-interference measures can be added to the existing system to reduce the impact of electromagnetic interference. 

This article provides solutions to the interference problems encountered by vortex flowmeters. Different interference factors have different effects on the flowmeter. Therefore, in actual measurement, it needs to be based on the specific situation. Analyze and process.
