Claim:
1. A method for determining a number of drops of a liquid metered with a drop frequency into a reactor, comprising the steps of: flowing a gas stream through the reactor; providing in the reactor a temperature, the temperature being greater than the boiling temperature of the liquid; metering a drop of the liquid into the reactor; transforming said drop of the liquid at least partially into the gas phase following entry into the reactor; detecting at a sampling rate a sequence of pressure signals of a pressure measuring transducer arranged within the gas stream, said pressure signals being dependent on pressure within the reactor, wherein the sampling rate is greater than the drop frequency; communicating the sequence of pressure signals or values derived therefrom to a control unit; and calculating by means of the control unit the number of drops of the liquid metered into the reactor from the sequence of pressure signals or from the values derived therefrom.
