Explosion-proof radar level meter play a vital role in industrial production. They can not only work safely in flammable and explosive environments, but also achieve accurate liquid level monitoring and early warning. The following is a detailed explanation of how the explosion-proof liquid level meter achieves accurate monitoring and early warning:
Working principle of explosion-proof liquid level gauge
The working principle of explosion-proof level gauges varies depending on their type, but most are based on physical principles for level measurement. For example:
- Magnetic turnover level meter: Based on the principle of buoyancy and magnetism, the float with a magnet floats up and down with the change of the liquid level, and then reflects the liquid level through the flip of the magnetic turnover column.
- Ultrasonic level meter: Using the principle of reflection of sound waves in the medium, the liquid level height is determined by measuring the time from transmission to reception of ultrasonic waves. Ultrasonic liquid level meter has the advantages of fast response speed and high measurement accuracy.
- Magnetic float ball liquid level meter: Based on the principle of buoyancy and static magnetic field, through the action of the magnet in the float ball and the sensor, the electrical amount in the circuit is changed to reflect the change of the liquid level.
The realization of accurate monitoring
- High-precision sensor: The explosion-proof liquid level meter uses high-precision sensors that can accurately sense changes in liquid level and convert them into electrical signals for transmission and processing.
- Advanced signal processing technology: Through the use of advanced signal processing algorithms and circuit design, the explosion-proof liquid level meter can filter out noise interference and improve measurement accuracy and stability.
- Real-time calibration and correction: Regular calibration and correction of the explosion-proof level gauge can ensure that it maintains high accuracy in the long term.
The realization of early warning function
- Preset alarm threshold: The user can set the level alarm threshold on the explosion-proof level meter according to the actual needs. When the level reaches or exceeds these thresholds, the level gauge will automatically trigger an alarm signal.
- Multiple alarm methods: explosion-proof liquid level meter usually supports a variety of alarm methods, such as sound and light alarm, relay output, etc. These alarm methods can ensure that the operator is reminded to take appropriate measures in time when the liquid level is abnormal.
- Remote monitoring and notification: Many modern explosion-proof level gauges also have remote monitoring and notification functions. By connecting the remote monitoring system or cloud platform, the operator can view the liquid level data in real time and receive alarm notifications, so as to achieve remote monitoring and management of liquid level changes.
Explosion-proof performance and safety
- Explosion-proof level certification: explosion-proof level gauges usually have the corresponding explosion-proof level certification (such as Ex explosion-proof certification), and can be used safely in flammable and explosive environments.
- Safety protection measures: The explosion-proof liquid level gauge is also equipped with a variety of safety protection measures, such as over-voltage protection, over-current protection, etc., to ensure its stable operation in harsh environments.
In summary, the explosion-proof liquid level meter realizes the accurate monitoring and early warning of the liquid level through the technical means of high-precision sensors, advanced signal processing technology, real-time calibration and correction, various alarm methods and remote monitoring functions. At the same time, its explosion-proof performance and safety protection measures also ensure its safe use in flammable and explosive environments.
