Title: Tumbling measure type rain gauge
Inventor: MARUYAMA KAZUO
IPC: G01W1/14
Filed: 1990-10-29
Abstract: PURPOSE:To improve measurement accuracy for a rainfall amount by providing a solenoid valve at a rainfall flow passage between an inlet and a tumbling measure, and interrupting the flow passage during a signal transmission from a sensor circuit. CONSTITUTION:When the predetermined rainfall amount is collected in a measure 4a, a tumbling measure 4 begins to tumble about a support point 6, and discharges rain water to a drain hole 8a. At this point, a sensor circuit 21 detects the tumbling motion of the measure 4 and sends a signal, thereby actuating a solenoid valve 22 for interrupting a flow passage in a drain passage 3a. Consequently, rain water stops to drop from a filter 3 to the measure 4a. The aforesaid tumbling motion continues and when the measure 4 nears a horizontal position, an electrical signal generation circuit detects the start of the tumbling motion and outputs a signal. Furthermore, when the measure 4 passes the horizontal position and begins to incline toward a stopper 7a, the electrical signal generation circuit is tuned off, and subsequently output from the sensor circuit 21 is interrupted. Then, the solenoid valve 22 opens for causing rain water to begin dropping toward a measure 4b, and the tumbling measure 4 contacts the stopper 7a, thereby stopping the tumbling motion. According to the construction, the inflow of excess rain water can be prevented after the predetermined rainfall amount is collected in the measuring glasses 4a and 4b.
