1. Operating temperature: -40 degrees - 80 degrees
2. Process pressure: (-0.02-0.1) MPa 3.
3. Ambient temperature: -40 degrees - 60 degrees
4. Ultrasonic level gauge is not suitable for working conditions: ultrasonic level gauge can not be used in vacuum, steam content is too high or there is foam on the liquid surface, temperature is too high or process pressure is high.
