The Level transmitters Animation shows different types of sensors working principles visually which includes Guided wave Radar Level transmitter, Ultrasonic Level transmitter, 2 Wire / 4 Wire Pulse type Radar Level transmitter, FMCW type Radar Level transmitter, and Capacitance type Level transmitter.
Level Transmitter Animation
The comparison of different types of level transmitters is shown below.
| Feature | Guided Wave Radar | Ultrasonic | 2-Wire/4-Wire Pulse Radar | FMCW Radar | Capacitance Level |
| Operating Principle | Uses guided microwave pulses through a probe. | Measures time-of-flight of sound waves. | Emits radar pulses and measures return time. | Frequency Modulated Continuous Wave (FMCW) radar emits frequency-modulated signals. | Measures change in capacitance between sensor and liquid. |
| Medium Compatibility | Suitable for liquids, solids, and slurries. | Ideal for liquids and some solids. | Suitable for liquids, solids, and powders. | Best for liquids, gases, and solids. | Works with liquids and non-conductive materials. |
| Accuracy | High accuracy, unaffected by temperature and pressure. | Moderate accuracy, affected by foam and vapor. | High accuracy, better in harsh environments. | Very high accuracy, even in challenging environments. | High accuracy in liquids, affected by material properties. |
| Measurement Range | Up to 30 meters. | Up to 15 meters. | Typically up to 30 meters. | Typically up to 80 meters. | Short range, usually up to a few meters. |
| Environmental Sensitivity | Not affected by temperature, pressure, or vapor. | Affected by temperature, pressure, and dust. | Unaffected by temperature and pressure. | Unaffected by harsh conditions. | Can be affected by buildup on the sensor or changes in material properties. |
| Power Requirements | Low power consumption. | Low power consumption. | Moderate power consumption (depends on 2/4 wire setup). | Higher power consumption than pulse radar. | Low power consumption. |
| Installation Complexity | Requires proper installation with probe. | Easy to install, no physical contact. | Medium installation complexity depending on wiring. | More complex installation due to technology. | Simple installation, requires a proper dielectric constant. |
| Cost | Moderate to high. | Low to moderate. | Moderate. | High due to advanced technology. | Low cost, economical solution. |
| Applications | Best for liquids, solids, slurries in tanks, silos. | Simple liquid applications (water, fuel). | Ideal for large storage tanks and process vessels. | Best for extreme conditions, long-range applications. | Used in water, chemicals, and food industries for liquid level measurement. |

Hey, Level transmitters animation rocks. Please post for all types of transmitters.
Animation really awesome dude. I liked the idea of having different level transmitters at one place. Publish more n more.
wonderful animated illustration.
