Device and method for determining the degree of disinfection of a liquid

摘要

The invention relates to a device and also a method for determining the degree of disinfection, and for determining the time point when a defined degree of disinfection is reached by a liquid, in particular drinking water, that is situated in a container which is light-permeable at least in a UV range. The device comprises in this case a UV measuring appliance for measuring the intensity of the UV radiation in the region of the container, a data analysis unit to which the values of the UV intensity which are measured by the UV measuring device are fed, and wherein the data analysis unit converts the UV intensity values measured at the start of a measurement at defined time points to form a characteristic, and wherein the data analysis unit compares the characteristics determined at defined time points with a predetermined characteristic, which predetermined characteristic corresponds to a defined degree of disinfection of the liquid, and wherein the device comprises at least one signal output appliance which, in the event that the determined characteristics reaches or exceeds the value of the predetermined characteristic, provides the signal output.

1. A device for determining the degree of disinfection or for determining the time at which a defined degree of disinfection of a liquid, particularly drinking water, which is located inside a container that includes a side wall that is transparent in at least one Ultra-Violet (“UV”) region, is reached, wherein the device comprises:
a UV measuring device configured to measure intensity of UV radiation from sunlight passing through the side wall of the device, in the region of the container, an analysis unit, to which the values for UV intensity measured by the UV measuring device are fed, and wherein the analysis unit being configured to convert the values for UV intensity, measured at defined points in time from the start of a measurement, to a characteristic value, and wherein the analysis unit is configured to compare the characteristic values calculated at defined time points with a predetermined characteristic value, which predetermined characteristic value corresponds to a defined degree of disinfection of the liquid, and wherein the device comprises at least one signal output device which is configured to emit a signal when the calculated characteristic value reaches or exceeds the predetermined characteristic value.
