The Rain Gauge is fabricated of heavy duty PVC, aluminum and stainless steel. It consists of an outer funnel, screen, inner funnel and tipping bucket assembly. Precipitation entering the collection orifice fills the calibrated tipping bucket assembly. When the bucket fills to the calibrated amount, the bucket tips. Another bucket is brought into place and the precipitation sample is discharged through the dump tubes to the ground below. This produces a switch closure which is detected by the electronics in the Transmitter. The electronics in the Transmitter count the switch closures from the rain gauge. In ramp mode, the counter drives a digital to analog converter which produces a current signal which increases as counts are accumulated. The current signal drives the output amplifier. In rain detector mode each tip of the bucket causes the output to change to full scale for a user selectable time period of 1 to 80 minutes. The timer in the rainfall detector mode is retriggerable meaning that a time period starts with each tip of the bucket. If bucket tips occur faster than the selected time period the output will remain continuously at full scale.
