Abstract
The invention relates to an economical pressure measuring device as well as to a favorable method for pressure determination, with which a pressure measurement can be performed from outside the high-pressure container. To that end, the device comprises an ultrasound transmitter mounted outside the pressure container and an ultrasound receiver by means of which transmitter and receiver the transit time of an ultrasonic pulse traveling through the liquid contained in the high-pressure container can be ascertained, and the method comprises generating an ultrasonic pulse outside the high-pressure container measuring the time that the ultrasonic pulse requires to traverse a defined distance calculating the pulse speed of the pulse in the liquid; and from that determining the pressure in the liquid.
