Recently, thanks to developments of measurement, control and communication techniques, the company has tried to make a retrenchment in the budget by bring computer applied equipments into the water processing section.
There are four types of measurement-control equipment, that is, Data Base, HMI, Network transmission apparatus, and Sensor. Therefore it is necessary to combine these equipments properly in order to operate the water clean processes. Among them, the role of water-level measurement is indispensable to the entire process. A trivial matter in that system may cause financial loss for the company due to stopping of water cleaning processes. It is, therefore, necessary to enhance the accuracy and reliability of the measurement of the water-level.
We introduce the new type of the water-level measurement by using a infrared near-by sensor, and show the results that it is possible to measure the current water-level stably by using the proposed sensor.
