Abstract: A reactor for production of a fluid reaction product includes a reaction chamber, a plurality of fluid connections to supply fluid reactants to the reaction chamber, a reception chamber located directly below the reaction chamber, a transfer device providing a fluid connection between the reaction chamber and the reception chamber so that the reception chamber receives a fluid reaction product produced in the reaction chamber, a control unit and a first device, arranged in the reaction chamber to be in direct contact with the supplied fluids to determine a filling level. The first device includes at least one switching point which is operatively coupled with the control unit such that the supply of the fluid reactants into the reaction chamber is controlled and carried out sequentially.

Abstract: The invention relates to a method and a device for monitoring a fluid flow delivered by means of a pump. In the method the pressure distribution of the fluid is continuously or quasi-continuously measured as actual values in partial areas of the pump stroke and compared with desired values. In the device at least one pressure sensor is provided for the continuous or quasi-continuous measurement of the pressure of a fluid at least in partial areas of the pump stroke and a comparator is provided for comparing the measured actual values of the pressure with desired values.
