摘要

A manometer (100; 700) for determining at least one pressure value (122), indicating a pressure of a fluid flowing in a pulsing manner in a phase of the pulsing flow, comprises a pulse wave indicator (110). The pulse wave indicator (110) is designed to obtain transit time information (112), describing the transit time of a pulse wave between a first location and a second location, and amplitude information (114), describing a change of a measurement signal based on the pulse wave between two phases of the pulse wave. The manometer (110; 700) additionally comprises a unit for determining the pressure value (120) that is designed to obtain a first pressure value (132), indicating a pressure of the fluid in a first phase of the pulsing flow, based on the transit time information (112) by means of an image (134), displaying the transit time of the pulse wave on the first pressure value (132). The unit for determining the pressure value (120) is further designed to determine a second pressure value (136), indicating a pressure of the fluid in a second phase of the pulsing flow, based on the first pressure value (132) and the amplitude information (114) by using an image (138), indicating a correlation that is dependent on the first pressure value (132) between the first pressure value (132), the second pressure value (136) and the amplitude information (114).
