Device for measuring a level of fluid in a container

摘要

A device for measuring a level of a fluid in a container by measuring the transit time of an emitted acoustic pulse to the fluid surface and of its return echo through a guide conduit. The transit time of the emitted acoustic pulse is prolonged so that the transit time is long enough to reliably separate the emitted decaying acoustic pulse from its echo. An approach region with a subsequent bend is provided in the acoustic guide conduit.
