1. A method 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, the high pressure pump designed to generate a pressure between 1000 and 6000 bar, the method comprising:
measuring a flow speed of the fluid flow flowing through a pipe of the high-pressure-side high-pressure pump outlet by means of at least one ultrasonic measuring device including an externally arranged ultrasonic measuring device, to obtain a measurement result of the flow speed, wherein the high-pressure-side high-pressure pump outlet is a thick-walled pipe having a ratio of the pipe internal diameter to the pipe external diameter of 1:1.5 to 1:5 and the ultrasonic measuring device is arranged on the outside on this thick-walled pipe;
transmitting the measurement result of the flow speed to an evaluation unit; and
computing a present flow value and the flow control variable from the measurement result of the flow speed by means of the evaluation unit.
