Abstract
Acoustic signals are transmitted through the fluid flow of a fuel delivery pump to a tank to be filled. From reflection signals the fluid level in the tank is detected and a timely disconnection of the pump can be effected in order to prevent fuel losses.
Claims27
A method for detecting fluid level in a tank or storage container being filled, the fluid level being detected at a distance in front of the opening of a filling means, wherein an acoustic signal is passed from a transmitter through the fluid flow in the filling means and from the filling means to the fluid in the tank or storage container being filled, wherein an echo signal resulting from the reflection of the transmitted acoustic signal at the fluid surface in the tank or storage container is passed back through the fluid flow from the filling means and into the filling means to a receiver, thereby enabling the fluid level in the tank or storage container to be detected.
An apparatus for detecting the fluid level in a tank or storage container being filled, the fluid level being detected at a distance in front of the opening of a filling means, comprising an acoustic transmitter and a receiver, means for passing acoustic signals through the fluid flow in the filling means and from the filling means to and from the fluid surface in the tank or storage container being filled, and means for detecting the fluid level in the tank or storage container being filled form the acoustic signals passed back from the fluid surface in the tank or storage container through the fluid flow from the filling means and into the filling means to the receiver.
