We adapted an available displacement meter for measuring the shape of the hot steel product in the continuous casting machine and the rolling mill. The meter is an ultrasonic level one, but it uses a water column instead of atmosphere as the propagation medium.
The characteristics of the meter are summarized as follows:
(1) Its effective range is about 100 mm, and the resolution is 0.05 mm.
(2) It is strong and reliable with usage of water column, therefor useful for in-line measurement.
(3) It is useful for the hot steel product as a target.
