Product Collection
Guided Wave Radar (Contact Type)
High-performance instruments engineered for accurate and reliable measurement of pressure and level in industrial processes.
Guided Wave Radar Transmitters
A Guided Radar Level Transmitter uses a probe or rod/cable that extends inside the tank. Radar pulses travel down the probe and reflect when they hit the material surface. This technology is also called Time Domain Reflectometry (TDR).
Key Characteristics
- Contact-type technology (probe touches the product)
- Uses guided microwave pulses
- Very stable in narrow or small tanks
- Unaffected by foam, vapor, and turbulence
- Works well with liquids with low dielectric constant
Best Applications
- Small tanks and vessels
- Storage tanks with agitators or internal obstructions
- Interface measurement (oil-water separation)
- Viscous or sticky liquids where non-contact radar may struggle
- Applications requiring extremely stable readings in small volumes
Radar Level Meter
Non-contact radar, also known as a radar level meter, measures level by emitting microwave signals (e.g., 26GHz, 80GHz) from the top of the tank. These signals reflect off the surface of the material, and the instrument calculates the distance based on the return time.
Key Characteristics
- Non-contact measurement (antenna does not touch the product)
- Uses microwave radar waves
- Narrow beam angle (especially 80GHz)
- Works well in harsh environments
- Very low maintenance
Best Applications
- High tanks or silos
- Solids (cement, grain, powder)
- Liquids with vapor or steam
- Corrosive or sticky liquids
- Pressurized or high-temperature tanks
Radar Level Meter vs. Guided Radar Level Transmitter
| Feature | Radar Level Meter (Non-Contact) | Guided Radar Level Transmitter (TDR) |
|---|---|---|
| Contact with Medium | No contact | Probe is in contact with medium |
| Technology | Microwave radar (26/80GHz) | Guided radar pulses (TDR) |
| Best For | Tall tanks, harsh environments, solids | Small tanks, interface measurement |
| Sensitivity to Conditions | Unaffected by dust/steam (80GHz) | Unaffected by foam/vapor |
| Installation Space | Needs free space above material | Ideal for narrow tanks |
| Maintenance | Very low | Requires cleaning on sticky media |
| Dielectric Requirement | Medium-to-high dielectric | Works well even with low dielectric liquids |
| Cost | Higher for 80GHz models | Often more affordable |
| Solids Measurement | Excellent (especially 80GHz) | Limited to some models |
Unlike non-contact radar sensors, guided radar (also known as Time Domain Reflectometry or TDR technology) uses a probe (waveguide) to direct radar pulses down to the material surface, ensuring accurate and stable readings even in challenging process conditions.
