Device for the ultrasound measuring of cylindrical test models
First Claim
1. A device for ultrasonic measuring of a cylindrical test specimen located in a liquid medium, the device comprising:
- at least one ultrasonic measuring head;
a cylindrical reference mandrel having a longitudinal axis that substantially coincides with the measuring axis of the device, the reference mandrel defining a fixed reference point with respect to the ultrasonic measuring head; and
at least one cylindrical auxiliary mandrel that extends substantially parallel to the reference mandrel, wherein the auxiliary mandrel is movable along a substantially circular path around the reference mandrel in order to be removably positionable between the ultrasonic measuring head and the reference mandrel.

Abstract
A device is provided for the ultrasonic measuring of cylindrical test specimen, in particular tubes and hoses, wherein said device can be filled with water or submerged in a water bath and is provided with at least one ultrasonic measuring head secured on the device. The device is characterized by a cylindrical reference mandrel, the longitudinal axis of which at least essentially coincides with the measuring axis of the device, and at least one cylindrical auxiliary mandrel that extends parallel to the reference mandrel, can be moved to a position between the ultrasonic measuring head and the reference mandrel, and can also be removed from this position.

10. A method of measuring a cylindrical specimen located in a liquid medium using an ultrasonic signal produced by at least one ultrasonic measuring head of a measurement device, the method comprising:
-
calibrating the measurement device using the following steps; (a) measuring a first transmit time for an ultrasonic echo from the ultrasonic measuring head to a cylindrical reference mandrel located substantially coaxially with the measurement axis of the device; (b) positioning a cylindrical auxiliary mandrel between the ultrasonic measuring head and the reference mandrel, and at a first known distance from the reference mandrel; (c) measuring a second transmit time for an ultrasonic echo from the ultrasonic measuring head to the reference mandrel; and (d) calculating the distance from the ultrasonic measuring head to the cylindrical reference mandrel based on the first transit time, the second transit time, and the first known distance; and measuring the cylindrical specimen using the following steps; (e) positioning the cylindrical specimen substantially coaxially around the reference mandrel; (f) measuring a third transit time for an ultrasonic echo from the ultrasonic measuring head to a boundary surface of the specimen; and (g) calculating a dimensional property of the specimen based on at least the third transit time. - View Dependent Claims (11)
