| 20090064776 | Floatless rain gauge - A rain gauge device is provided that uses a plurality of conductivity sensors to determine liquid levels. Certain rain gauge devices include a plurality of conductivity sensors fixed along the length of a support member, wherein each conductivity sensor comprises at least two selectable electrodes for sensing the presence of a liquid by measuring a conductivity of the liquid between these electrodes when a liquid is present between the sensing electrodes, and an electronic command unit adapted to apply a voltage between a common electrode and a selected electrode. Level measuring devices are also provided that comprise a collector, a measuring tube, a plurality of conductivity sensors and an electronic command unit for applying a voltage across the conductivity sensors and for converting the conductivity measured into a digital output for each increment. Methods of use and operation are also provided. | 03-12-2009 |
