	~~'''~~Abstract~~'''~~
	A railroad [[tank car]] containing liquid, has a tube through its top, with the closed lower end of the tube in the liquid. A float slidable along the tube exterior is magnetically coupled to an ultrasound reflector piston inside the tube so that, when the tube is in the liquid in the tank, the float determines the height of the piston inside the tube. An ultrasonic transducer atop the tube sends ~~pulses~~ down the tube and which are reflected by the piston to the transducer. A computer coupled to the transducer determines and displays the liquid level. The piston is cup-shaped with a known distance between reflecting surfaces for use in the computer to produce a display value corrected for temperature variations.		== Abstract ==

			A railroad [[tank car]] containing liquid, has a tube through its top, with the closed lower end of the tube in the liquid. A float slidable along the tube exterior is [[magnetically]] coupled to an [[ultrasound]] reflector [[piston]] inside the tube so that, when the tube is in the liquid in the tank, the float determines the height of the piston inside the tube. An ultrasonic [[transducer]] atop the tube sends [[pulse]]s down the tube and which are reflected by the piston to the [[transducer]]. A computer coupled to the [[transducer]] determines and displays the liquid level. The piston is cup-shaped with a known distance between reflecting surfaces for use in the computer to produce a display value corrected for temperature variations.
