Frequently Asked Questions About Level Measurement

What’s the difference between ultrasonic and radar level sensors?

Ultrasonic sensors use sound waves to measure distance to the liquid surface and are ideal for clean, simple applications. Radar (FMCW) and guided-wave radar (TDR) use microwave signals and perform better in steam, dust, or high-temperature conditions.

Can SRB level transmitters be used for solids as well as liquids?

Yes. Radar-based transmitters are effective for bulk solids, powders, and granules where ultrasonic sensors may struggle with dust or changing material density.

What’s the advantage of guided-wave radar (TDR)?

Guided-wave radar (TDR) transmits along a probe, making it less affected by vapor or foam. It’s an excellent choice for small tanks or complex geometries where non-contact sensors may experience signal interference.

Do SRB’s level sensors support remote monitoring or control?

Yes. SRB can integrate your level sensors into MeterConnex for centralized data visualization and alarm notifications, ensuring proactive maintenance and process optimization.

Which industries use SRB level sensors?

Our sensors are used in water and wastewater treatment, chemical processing, food and beverage, and energy systems, offering accuracy and durability in harsh industrial environments.
