Filed: 1989-09-25
Abstract: PURPOSE:To accurately grasp the time of cleaning by interrupting light emitted from a light emitting element when some constant amount of algae or red rust is generated in a water storage tank and lowering voltage output to a controlling device from a photodetector. CONSTITUTION:Light is periodically emitted from a light emitting element 2 by a controlling device 5. When some constant amount of algae is generated, light emitted from the element 2 is interrupted by algae and voltage output to the controlling device 5 from a photoreceptor 3 is lowered. When this voltage exceeds the preset prescribed value, an excess of the voltage is judged by the controlling device 5. A pollution detection signal is output to a transmitter 6 from the device 5. In such a way, when the pollution detection signal is output from the device 5, this effect is announced to a monitoring center 8 from the transmitter 6 via a telephone circuit 7. Thereby a monitor can know the degree of progress of pollution and then a time of cleaning is accurately grasped.
