A method and a high-pressure system for determining a flow control variable of a fluid flow flowing through a high-pressure-side high-pressure pump outlet of a high-pressure pump are provided. An externally arranged ultrasonic measuring device measures a flow speed of a fluid flow flowing through a pipe of the high-pressure-side high-pressure pump outlet. A use of an ultrasonic measuring device is provided for determining a flow value to be achieved of a fluid flow flowing through a thick-walled pipe. The ultrasonic measuring device is arranged on the outside on the thick-walled pipe of the high-pressure pump outlet. The pipe has a ratio of the internal diameter to the external diameter of 1:1.5 to 1:5. The ultrasonic measuring device dynamically measures the flow speed of the fluid flow and transmits this measured flow speed to an evaluation unit to compute a current flow value and the flow control variable.
