    • A transmitter for providing inventory or inventory transfer information on industrial sites is described, for measurement of mass (M), weight (W), volume (V), level (L) and/or density (p) of a product (1) in a vessel (3) comprising: a level sensor (5), comprising: a conductive probe (9) extending into the vessel (3), means (11, 13) for generating and sending short electromagnetic pulses (S) down the probe, means (15) for reception of echoes (E) of the pulses (S) reflected at a surface of the product (1), means (17) for determining a time of flight (t) needed for a pulse (S) to travel down the probe (9) and its echo (E) to return, a pressure sensor (7), mounted on the probe (9), and a signal processing unit (45) for determining mass (M), weight (W), volume (V), level (L) and/or density (p) based on measurement signals supplied by the level sensor (5) and the pressure sensor (7).
    • 描述了用于在工业场所提供库存或库存转移信息的变送器,用于测量产品(1)的质量(M),重量(W),体积(V),水平(L)和/或密度(p) 在容器(3)中,包括:液位传感器(5),包括:延伸到所述容器(3)中的导电探针(9),用于在探头下方产生和发送短电磁脉冲(S)的装置(11,13) 用于接收在产品(1)的表面反射的脉冲(S)的回波(E)的装置(15),用于确定脉冲(S)所需的飞行时间(t)的装置(17) 沿探针(9)及其回波(E)向下移动,安装在探头(9)上的压力传感器(7)和用于确定质量(M),重量(W)的信号处理单元(45) (V),液位(L)和/或密度(p),基于由液位传感器(5)和压力传感器(7)提供的测量信号。
