The frequency comparator ( 106 ) converts the first pulse signal ( 10202 ) and the second pulse signal ( 10402 ) into an adjusted signal ( 10602 ). The control module ( 107 ) compares the adjusted signal ( 10602 ) with an expectation value ( 10818 ) to obtain a comparative result signal. According to the comparative result signal, the control module ( 107 ) adjusts the second oscillation frequency, so that the second oscillation frequency and the first oscillation frequency have a constant frequency difference.

Material level indicator

A material level indicator includes a probe, first and second signal compensating units, arranged at first and second ends of the probe respectively, and a controlling module arranged at the first end and includes a signal processor, a signal emitter, and a signal receiver. The second end is opposite to the first end. The signal processor is connected to the signal emitter and the signal receiver. The signal emitter emits an electromagnetic signal from the first end to the second end of the probe. The first and second signal compensating units reflect the electromagnetic signal, and the signal processor generates first and second time interval differences according to the reflected electromagnetic signal received by the signal receiver. The signal processor calibrates an environmental coefficient and indicates a dielectric coefficient of the material according to the first and second time interval differences respectively.
