Feejoy is a professional manufacturer of Radar Level Transmitters. Our radar level transmitter uses radar technology to continuously measure liquid levels without contact. The sensor sends microwave signals towards the liquid from above and the surface of the liquid reflects the signal back to the sensor. The radar level sensor then uses the received microwave signal to determine the distance to the liquid surface and calculate its height. This type of radar level transmitter is an excellent alternative to differential pressure instruments, magnetostrictive, radio frequency admittance, and magnetic pirated instruments. The measurement technology of our radar level transmitter is usually used for measuring liquid levels and is not affected by factors such as vacuum, dust, temperature, pressure changes, steam, and falling gases. As a leading manufacturer of radar level transmitters, we are committed to providing high-quality products and services to our customers.

Advantages of Radar Level Transmitter

This radar level transmitter is a superior alternative to other instruments such as differential pressure, magnetostrictive, radio frequency admittance, and magnetic pirated instruments. Its measurement technology is typically used to measure liquid levels and is not affected by environmental factors like vacuum, dust, temperature, pressure changes, steam, or falling gases.

As a top manufacturer of radar level transmitters, we are committed to providing high-quality products and services to our customers.


  • Modern high-frequency radars are generally radar level gauges operating in the K-band (24-26 GHz). The higher the frequency, the shorter the electromagnetic wavelength, making it easier to get better reflections on inclined solid surfaces. The narrow beam width can effectively avoid obstacles, and a higher frequency can allow the use of a smaller antenna.

  • FMCW FM continuous-wave microwave level meters simultaneously transmit and receive signals and emit more microwave signals at the same time. This solid-wave measurement can reduce wave loss in measuring high dust solid silos.

  • Solid-state mid-and high-frequency FM radars are excellent level gauge and level transmitter, providing accurate and reliable measurements, especially for media such as PP powder and PE powder in the chemical industry. Currently, there are no high-frequency radar level gauges that work above the K band due to technical limitations.

Radar Level Transmitter Used in Some Large Solid Silos

One of the main challenges in level measurement today is accurately measuring large solid silos, especially when they are filled with dust and disturbances within 50-100 meters. Capacitors or guided wave radar TDRs are often subjected to strong tensile loads during unloading, which can damage the instrument or even pull down the roof of the silo. Mechanical instruments like heavy hammers also require frequent maintenance, and the high dust conditions can exceed the capabilities of non-contact ultrasonic level sensors.

High-frequency FM radar technology is the ideal solution for measuring levels in large solid silos. As a specialized level sensor supplier, Feejoy has over 18 years of experience in custom-manufacturing radar level transmitters based on specific customer requirements such as material, power output, accuracy, sensor type, and more.

Radar Level Transmitter FAQs

What is radar level transmitter?

Radar waves are a special form of electromagnetic waves. Radar level transmitters use the special properties of electromagnetic waves to detect level.

How to better the effect of radar level transmitter?

The higher the frequency of the radar wave, the smaller the launch angle, the greater the energy (magnetic flux or field strength) per unit area, the smaller the attenuation of the wave, and the better the measurement effect of the radar level transmitter.
