摘要： The invention provides a level detection device (32) having a tube (34) which, in use, contains a material (14) for which its level in the tube (34) is to be measured. An ultrasonic transducer (10) is provided at one end of tube (34) for emitting an acoustic waveform that reflects off the surface of the level and returns to the ultrasonic transducer (10) to allow computation of the level from the time periods of the emitted and reflected acoustic waveforms. A flared section (22) within tube (34) diverges from adjacent ultrasonic transducer (10) towards the inside wall of tube (34) above the level, whereby, in use, the measured reflected waveform has substantially reduced signal distortion due to flare (22).

摘要： The invention provides an undershot sluice gate (17) to control flow of liquid through an open channel (10). The gate (17) includes a gate leaf (18) adapted to be raised and lowered by a control means (22) to allow flow of liquid along open channel (10). Gate leaf (18) has at least a pair of opposing liquid level sensors (44, 46) on, or in, gate leaf (18) to provide measurement of liquid level upstream and downstream of gate leaf (18). The sensors (44, 46) are located at a predetermined distance from the lowermost edge of gate leaf (18) to allow said measurements without disturbance from the fluid flow profile resulting from movement of liquid beneath the lowermost edge of gate leaf (18).
摘要翻译：本发明提供了一种下流闸门（17），用于控制液体通过开放通道（10）的流动。闸门（17）包括适于通过控制装置（22）升高和降低以允许液体沿开放通道（10）流动的闸门叶片（18）。闸门叶片（18）在闸叶（18）上或栅栏叶片（18）中至少有一对相对的液位传感器（44,46），以提供对门叶（18）上游和下游的液位的测量。传感器（44,46）位于与闸叶（18）的最下边缘预定的距离处，以允许所述测量而不受来自由叶片（18）的最下边缘下方的液体移动引起的流体流动剖面的干扰。
