How to Select an Explosion-Proof Ultrasonic Level Gauge [Dayu Electronics]
When selecting an explosion-proof ultrasonic level gauge, you can start from aspects such as the properties of the measured substance, installation environment, measurement accuracy, signal processing capability, and after-sales service. The following is a detailed introduction:
Select based on the properties of the measured substance
? Liquid characteristics: For different measured substances, it is necessary to select an ultrasonic level gauge with corresponding frequency and probe. For example, for liquids with higher viscosity, a lower frequency probe should be selected; for pure liquids, a higher frequency probe can be selected.
? Corrosiveness: Since explosion-proof ultrasonic level gauges often come into contact with chemicals or corrosive liquids, equipment components made of corrosion-resistant materials must be selected to ensure long-term stable operation. When selecting installation materials, evaluation should be based on the liquid characteristics and environmental conditions, and materials that can resist corrosion and erosion should be chosen.

Select based on installation environment
? Explosion-proof rating: Explosion-proof ultrasonic level gauges have different explosion-proof ratings, and the selection should be based on the actual requirements of the installation environment. For example, in flammable and explosive environments in the chemical industry, equipment with a higher explosion-proof rating should be selected. Common explosion-proof standards include EX explosion-proof certification (e.g., ATEX, IECEx, etc.).
? Sealing rating: During level measurement, the explosion-proof ultrasonic level gauge needs to have good sealing and waterproof performance to ensure the reliability and stability of the equipment in harsh working environments. Appropriate sealing and waterproof measures can reduce the impact of moisture, dust, chemicals, etc. on the equipment, extend its service life, and improve operational safety.

Select based on measurement accuracy
The accuracy of the ultrasonic level gauge is also an important factor in model selection. In some industrial applications, the measurement accuracy of liquid level is very high, so it is necessary to choose an explosion-proof ultrasonic level gauge with higher accuracy. Generally, explosion-proof ultrasonic level gauges can provide high-precision liquid level measurement with accuracy up to 0.3% and can resist various interference waves. They are not affected by the viscosity, density, or corrosiveness of the liquid. Through automatic calibration functions, the instrument can perform real-time automatic calibration to maintain the highest measurement accuracy.

Select based on signal processing capability
Modern explosion-proof ultrasonic level gauges usually have powerful signal processing capabilities, which can handle complex signals and improve measurement accuracy. Equipment with corresponding signal processing capabilities should be selected according to actual needs.
