Information

As a device widely used in industrial flow measurement, Electromagnetic Flowmeter can reliably measure the flow of various media in most cases. However, there are some special media that may affect the measurement of the Electromagnetic Flowmeter or even prevent it from being accurately measured. This article will explore which media cannot be measured by Electromagnetic Flowmeters.

1. Influence of the conductivity of the medium: The working principle of the Electromagnetic Flowmeter is based on the influence of the conductive medium on the magnetic field. Therefore, the Electromagnetic Flowmeter cannot accurately measure non-conductive media.

2. The viscosity of the medium is too high: High viscosity media will affect the normal operation of the electrodes and sensors in the Electromagnetic Flowmeter, resulting in inaccurate or impossible measurement results.

3. Non-uniform medium: When the flow state of the medium is uneven or contains large particles, it will affect the measurement accuracy of the Electromagnetic Flowmeter and even make it impossible to measure.

4. Bubbles or gases in the liquid medium: When bubbles or gases exist in the liquid medium, they will interfere with the sensor of the Electromagnetic Flowmeter, causing measurement errors and even inability to perform accurate measurements.

Why can’t Electromagnetic Flowmeters measure non-conductive media? Answer: The working principle of the Electromagnetic Flowmeter is based on the influence of conductive media on the magnetic field. Non-conductive media cannot produce effective measurement signals. How to judge whether the viscosity of the medium is too high to affect the measurement of the Electromagnetic Flowmeter? Answer: It is usually judged whether the viscosity of the medium exceeds the applicable range of the Electromagnetic Flowmeter through the physical property parameters of the medium and experimental verification before measurement. What is the impact of non-uniform media on Electromagnetic Flowmeters? Answer: Non-uniform media will cause unstable flow conditions, thus affecting the measurement accuracy of the Electromagnetic Flowmeter. How does the Electromagnetic Flowmeter respond when there are bubbles or gases in the liquid medium? Answer: The interference of bubbles on the Electromagnetic Flowmeter can be reduced by improving pipeline design and adding bubble removal devices.

Summary: Although the Electromagnetic Flowmeter is a universal flow measurement device, there are still situations where some media cannot be accurately measured. Understanding these conditions will help you correctly select the appropriate flow measurement equipment and enable more accurate flow measurement and control in practical applications.
