An apparatus for injecting chemicals using a slope sensor is provided to inject a chemical solution into the storage tank according to the sensed flow amount by simply sensing a flow amount of raw water that flows into a storage tank in a small water supply system by a flow sensor using a slope sensor. An apparatus for injecting chemicals using a slope sensor comprises: a flow sensor(40) for sensing a flow amount by measuring a slope of a slope sensor varied according to the flow amount of raw water that flows into the storage tank in a small water supply system for storing the raw water by flowing raw water that has been collected from an intake reservoir(1) into a storage tank(4) through a water pipe(3); and a chemical injector(50) including a chemical tank(51), a chemical injection tube(52), a chemical injection pump(53) and a chemical solution level sensor(54) to inject the chemical solution into the storage tank according to the flow amount sensed by the flow sensor, wherein the flow sensor includes a flowing path installed in an end of the water pipe, a rotary bar installed rotatably in the flowing path, a buoy fixed to an end of the rotary bar, and a slope sensor for sensing a rotation amount of the rotary bar such that the flow amount is calculated from a cross section of the flowing path and a slope angle sensed by the slope sensor. |
