Title:
ULTRASONIC DENSITOMETER
Document Type and Number:
Japanese Patent JP2005091318
Kind Code:
A
Abstract:
To improve usability at a high temperature and prevent a liquid to be measured from becoming contaminated, when using an ultrasonic densitometer.
The ultrasonic densitometer 10 is provided with a measuring body 20 which is immersed in the liquid to be measured, and which has an ultrasonic transmitter 25 for transmitting the ultrasonic waves toward the liquid to be measured and an ultrasonic receiver 25 receiving ultrasonic waves propagating through the liquid to be measured. The measurement body 20 is made up of a ceramic material.
