Abstract
A pressure gauge for determining at least one pressure value describing a pressure of a fluid flowing in a pulsating manner in a phase of the pulsating flow, includes a pulse wave characterizer. The pulse wave characterizer is configured to obtain transmit time information of a pulse wave, and amplitude information of the pulse wave. The pressure gauge additionally includes a pressure value determiner configured to obtain a first pressure value describing a pressure of the fluid in a first phase, on the basis of the transmit time information and while using a mapping. The pressure value determiner is further configured to obtain a second pressure value describing a pressure of the fluid in a second phase, on the basis of the first pressure value and the amplitude information while using a mapping.
