Liquid level measurement device
Abstract:
The present invention relates to a device (10) for providing a temperature compensated measurement of the level of a liquid (14) in a tank (12; 30). The device comprises a transducer (22) for transmitting and receiving acoustic signals, and a waveguide (24) connected to the transducer and adapted to extend into the liquid. The device is characterized by means (16; 18; 40) for directing a flow of liquid originating from the tank of along the exterior of a portion of the waveguide which during operation is located above the liquid level. The present invention also relates to a corresponding method for providing a temperature compensated measurement of the level of a liquid in a tank.
Abstract(Chinese):

本发明涉及一种用于在罐（12; 30）中提供液体（14）的液位的温度补偿测量的装置（10）。 该装置包括用于发送和接收声信号的换能器（22）和连接到换能器并适于延伸到液体中的波导（24）。 该装置的特征在于用于沿着波导的一部分的外部引导来自罐的液体流的装置（16; 18; 40），其在操作期间位于液面之上。 本发明还涉及一种相应的方法，用于提供罐中液体的温度补偿测量。
