Abstract :
A novel low-power microwave sensor for level gaging in storage tanks has been developed. By using a PLL-controlled gated oscillator this FMCW radar can be operated in a standard 4-20 mA loop without additional supply power. The chosen system design features a fast settling time of the oscillators to achieve a quasi-continuous frequency sweep, resulting in a precise, stable and reliable level measuring system.
