Measure in the range of 100 mm / h. The specific aspect is
In a water droplet counting type, rainfall is converted into water droplets of a certain size and dropped into the shell between the lamp and the photoelectric converter. Normally, when the rainfall for one minute is accumulated and it continues to fall at the same intensity, 1
The amount of rainfall (mm / h) per hour is measured, converted into a pulsed electric signal and output. As described above, if the amount of rainfall per hour (mm / h) is estimated based on the amount of rainfall per minute, the response can be quickly performed. Incidentally, the measurement of general rainfall is represented by the rainfall actually dropped in one hour, so it is not clear until one hour has passed, so the response is slow.

る。The values of the water level (flow rate), measurement time (measurement time) and communication time of the river and regulating pond are automatically changed according to the measured values of the rain detector E. In other words, if the flow (water level) changes (increases) rapidly and greatly due to abnormal heavy rainfall or prolonged rainfall, the control of the river R, regulating pond P, etc. will be performed well with the normal measurement time gap and set values. It is not possible, and there is a possibility of flooding and flooding. For example, when the rainfall becomes dangerous, the measurement time interval and the communication time interval are changed from 4 hours to 80 minutes to cope with a sudden water level change prediction, and the set water level (flow rate) is set to 65% of the dangerous water level (flow rate). % Value to respond to the expectation of a large increase in water level after valve control, or change the valve opening. Thereby, it is possible to cope with a very rare case and a normal setting range, or for both a dry season and a rainy season.
