FAQs

What is a radar level transmitter and how does it work? A radar level transmitter is an instrument used to measure the level of liquids, solids, or slurries in a container. It works by emitting microwave radar signals towards the material surface. The time taken for the signal to reflect back to the transmitter is measured, and this time-of-flight data is converted into a distance measurement, providing an accurate level reading. This non-contact method ensures reliability even in challenging process conditions.

What are the advantages of radar level transmitters over ultrasonic transmitters? Radar level transmitters offer several advantages over ultrasonic variants. They are not affected by temperature changes, vapor, dust, or vacuum conditions, which can impede ultrasonic signals. Radar provides better accuracy and reliability in applications with foam, turbulence, or low dielectric constants. They also have a higher pressure and temperature rating, making them suitable for more extreme industrial environments.

What industries commonly use radar level transmitters? Radar level transmitters are widely used across various industries including oil and gas for tank level measurement, chemical processing for corrosive liquid monitoring, water and wastewater treatment for basin and tank level control, food and beverage for hygienic applications, pharmaceuticals for precise batching, and power generation for coal and ash silo monitoring. Their versatility makes them applicable wherever accurate and reliable level measurement is critical.

What is the difference between guided wave radar and non-contact radar? Guided wave radar uses a probe or cable that extends into the vessel to guide the radar pulse, making it suitable for applications with low dielectric constants or where space constraints exist. Non-contact radar emits signals through air from an antenna without physical contact with the medium, ideal for corrosive, sticky, or hygienic applications where probe contact is undesirable. The choice depends on the process medium and installation conditions.
