Project Overview

The magnetic flap level gauge is a common liquid level measuring instrument and is widely used in various liquid storage tanks and reaction kettles. However, its measurement accuracy may be affected due to various factors. This article will introduce several methods to improve the measurement accuracy of magnetic flap level gauge.

1. Choose the appropriate sensor

The sensor of the magnetic flap level gauge is one of the key factors that affects the measurement accuracy. Different sensors have different measurement accuracy and application range, so it is necessary to choose the appropriate sensor according to actual needs. When selecting a sensor, factors such as the nature of the liquid to be measured, the material of the storage tank or reactor, and measurement accuracy requirements need to be considered.

2. Eliminate magnetic field interference

The magnetic flap level gauge uses the principle of magnetic field to measure, so magnetic field interference may have a greater impact on the measurement results. In order to improve the measurement accuracy, the magnetic field needs to be shielded and anti-interference designed. High magnetic permeability materials can be wrapped around the sensor to reduce magnetic field interference, while the circuit design can be optimized to improve anti-interference capabilities.

3. Adjust the flap spacing

The flap spacing is an important parameter of the magnetic flap level meter, which directly affects the measurement accuracy. If the distance between the flaps is too large, the measurement error will increase; if the distance between the flaps is too small, problems such as blockage will occur. Therefore, after selecting a suitable sensor, the flap spacing needs to be adjusted according to actual needs to obtain higher measurement accuracy.

4. Correction of liquid level fluctuation

Liquid level fluctuation is a common phenomenon in storage tanks or reactors, which will affect the measurement results of the magnetic flap level gauge. In order to improve measurement accuracy, liquid level fluctuations need to be corrected. A wave measurement device can be added to the magnetic flap liquid level gauge to obtain more accurate measurement results by monitoring and correcting liquid level fluctuations in real time.

5. Regular maintenance and calibration

After long-term use, the magnetic level gauge may experience some wear and error, so it requires regular maintenance and calibration. You can regularly check whether the sensitivity and linearity of the sensor have changed. If the error is found to be large, it needs to be adjusted and calibrated in time. In addition, the sensor and flap need to be cleaned regularly to avoid dust, impurities, etc. from affecting the measurement results.

In summary, methods to improve the measurement accuracy of magnetic flap level gauges include selecting appropriate sensors, eliminating magnetic field interference, adjusting flap spacing, correcting liquid level fluctuations, and regular maintenance and calibration. By taking these measures, the measurement accuracy of the magnetic flap level gauge can be improved to better meet the measurement needs in industrial production.
