CALIBRATION OF A LEVEL GAUGE SYSTEM |
摘要 |
A method of calibrating a level gauge system using electromagnetic signals to determine a filling level of a product in a tank. The level gauge system comprises a real time sampler for sampling a reflection signal with a sampling period between consecutive samples. The method comprises the steps of: receiving timing signals from a wireless communication network; generating time stamp signals based on the timing signals; registering a number of the sampling periods between a first time stamp signal and a second time stamp signal; and determining the sampling period based on the registered number of sampling periods and a time between the first time stamp signal and the second time stamp signal. Various embodiments of the present invention provide for high accurate determination of the filling level in a tank without the need for a temperature stable and highly accurate clock reference in the level gauge system.
