RQ30 Non-Contact Radar Flow Measurement Device

I. Product Advantages

1. The RQ30 surface velocity sensor utilizes a new generation of microstrip patch antenna technology, achieving a qualitative leap in performance.

2. SOMMER RQ30 employs linear polarization, providing excellent resistance to rain and snow interference.

3. Strong capability to resist rain and snow interference.

4. SOMMER RQ30 has very low power consumption, only one-third that of the Stalker SVR.

5. The RQ30 uses a high Q-value (5000–10000) microwave dielectric resonant oscillator as the frequency stabilization component, offering advantages such as low phase noise, high frequency stability, easy tuning, and low power consumption compared to Gunn effect oscillators.

6. SOMMER RQ30 comes with built-in FFT (Fourier Transform) software functionality, enabling Fourier transformation of echo signals.

7. SOMMER RQ30 integrates a waterproof RS485 standard interface directly on the mainboard, using a transparent RS485 communication protocol for easy integration into telemetry systems.
