Abstract
The spaced plates of a capacitor are immersed in water adjacent water intake grating so that water flowing toward the grating passes between and in contact with the plates so that frazil ice may accrete on the facing surfaces of the plates. As accretion occurs, the capacitance changes to indicate the amount of accretion of frazil ice which is detected thereby providing an indication of the amount of accretion of frazil ice on the grating.
Claims6
The method of detecting the accretion of frazil ice on water intake grating comprising providing a capacitor including a pair of spaced conductive plates having substantially parallel facing surfaces, immersing said plates in water adjacent water intake grating so that water flowing toward the grating passes between said plates and in contact with said surfaces so that frazil ice may accrete on said surfaces as frazil ice accretes on the grating, and detecting changes in capacitance of said capacitor to indicate the amount of accretion of frazil ice on said surfaces, thereby providing an indication of the amount of accretion of frazil ice on the grating.
