推进剂用超声液位仪

Ultrasonic level meter for propellant

一类发射作的推进剂具有剧毒、强腐蚀、易挥发、易燃易爆等特点，一般贮存在密封容器中，如运用通常的接触式仪器对其储罐中的液位进行检测，则仪器使用寿命很短．本文介绍了对运输、贮存容器中的液位，能进行非接触式精确测量的超声液位仪．

A sort of propellant of projected body, having the characteristics of being virulent, strongly erosive, volatile, combustible, explosive etc., is commonly preserved in hermetic containers. For such case, the lifetime of the level meter is short if an usual contact measuring level meter is used to detect the level in the container. In this paper, a non-contact measuring ultrasonic level meter is presented which is used to measure the container level in the transport or the storage state.
