Ultrasonic level meter

The utility model discloses an ultrasonic level meter, including being used for producing and receiving hyperacoustic sensor, the surface of sensor be provided with be used for preventing liquid condense in the liquid isolation layer on the surface of sensor. Implement the utility model discloses, surface through being used for producing with receiving hyperacoustic sensor sets up the liquid isolation layer, prevents that liquid condenses in the surface of sensor in the use, makes the unable normal work of sensor, influences ultrasonic level meter's detection accuracy, owing to only need to set up the liquid isolation layer on the surface of sensor, simple structure, it is with low costs. 本实用新型公开了种超声波物位计，包括用于产生和接收超声波的传感器，所述传感器的表面设置有用于防止液体凝结于所述传感器的表面的液体隔绝层。实施本实用新型，通过在用于产生和接收超声波的传感器的表面设置液体隔绝层，防止在使用过程中液体凝结于传感器的表面，使传感器无法正常工作，影响超声波物位计的检测准确度，由于只需在传感器的表面设置液体隔绝层，结构简单，成本低。
