Level Measurement

Types and Features of Level Measurement Instruments

1. New RF Capacitive Level Meter

  • Technology: Uses radio frequency (RF) and microprocessor technology

  • Advantages:

    • Low temperature drift

    • Easy calibration

    • Strong anti-adhesion capability

  • Applications:

    • Continuous level measurement for liquids and bulk solids

    • Harsh environments (high temperature, strong corrosion, sticky materials, dusty conditions)

2. Level Switch

  • Function: Detects pre-set levels of granular solids, slurries, and interfaces

  • Measurement Methods:

    • Ultrasonic

    • High-sensitivity capacitive sensing

3. Main Types of Level Meters

Type Features Applications
Hydrostatic Level Meter Measures level via pressure, can be direct or remote seal mounted Tanks and pressurized vessels
Ultrasonic Level Meter Non-contact measurement Liquids and granular solids
Radar Level Meter Narrow beam angle (as low as 5°), high interference immunity, excellent accuracy Powders, dust, and liquids
Capacitive Level Meter Handles high temp/pressure, resists dust, buildup, steam, and condensation Challenging process conditions

4. Other Level Measurement Technologies

  • 3D Level Scanner

  • RF Admittance Level Meter (capacitive principle)

  • Float Level Meter

  • Magnetostrictive Level Meter

  • Microwave Radar Level Meter
