Method for determining filling level in a tank using radar
A recently filed patent (Publication Number: US20230314202A1) describes a method and system for determining the filling level of a product in a tank using a radar level gauge system. The method involves generating and transmitting an electromagnetic signal towards a corner reflector formed by the surface of the product and the tank wall. The signal is then reflected back and received by the radar level gauge system. By analyzing the propagation direction of the reflected signal and the known horizontal distance between the system and the corner reflector, the filling level of the product can be determined.
In one embodiment of the method, a sequence of transmit signals is successively propagated in different directions in relation to a line normal to the surface of the product. The propagation direction of the reflected signal is determined based on the propagation direction of the transmit signal. Additionally, the method includes determining the presence of product in the tank atmosphere based on the timing relation between the transmit signal and the reflection signal, as well as the distance along a straight line between the radar level gauge system and the corner reflector.
The patent also describes a method for verifying the operation of the radar level gauge system. This method involves generating and transmitting a second transmit signal vertically towards the surface of the product. The reflected signal is then received and analyzed to determine the filling level. The operation of the radar level gauge system is verified by comparing the filling level determined based on the propagation direction of the first reflection signal with the filling level determined based on the timing relation between the second transmit signal and the second reflection signal.
The radar level gauge system described in the patent includes a transceiver, an antenna arrangement, and processing circuitry. The transceiver generates and transmits the transmit signal and receives the reflection signal. The antenna arrangement is configured to transmit the signal towards the corner reflector and receive the reflection signal. The processing circuitry analyzes the propagation direction of the reflection signal and determines the filling level based on this information and the known horizontal distance between the system and the corner reflector.
Overall, this patent presents a method and system for accurately determining the filling level of a product in a tank using a radar level gauge system. The method includes analyzing the propagation direction of reflected signals and comparing them with timing relations to verify the system's operation. This technology has potential applications in various industries where accurate measurement of product levels in tanks is crucial.
