Abstract
PURPOSE: To enable to output the water level in digital value directly, by integrating the counter through the pulse application in order from the lower conductor in the lower tip and stopping the integration when the conductor not immersed in water is applied for power.
CONSTITUTION: When the water level is for example at the level of LL', if the measuring start pulse ST is fed to the gate G1, the first pulse t1 is fed to the counter CT2 and the content is reset. Next, the second pulse t2 resets FF and the gate G2 is closed. When the third pulse t3 is fed to the decoder DEC3, the decoder selects band conductor 21 and distributes the pulse t3 via the connector 4. Since the conductor 21 is connected via the conductor 3 and water, the pulse t3 is fed to the amplifier A to set FF and open the gate G2. Further, the fourth pulse t4 adds the counter CT2 and the content is made to 1. The similar operation is repeated hereinafter, and the content of the counter is 4, and the water level is outputted in digital value.
