OSi’s APG-815-DS (All Precipitation Gauge) uses proven optical scintillation technology and offers many performance and maintenance advantages over traditional tipping bucket and weighing type rain gauges.
These advantages include:
In addition to rain and snow water equivalent rate and accumulation the APG-815-DS reports present weather codes in NWS and WMO formats. Traditional rain and precipitation gauges cannot report present weather codes.
Adaptive Heater Technology (AHT) is used to conserved power. The lens heaters are only energized when needed. This means the APG-815-DS is appropriate for solar powered installations. Solar
power combined with OSi cellular phone makes the APG-815-DS ideal for remote installations and networks.
OSi’s sensors have more than 600 million hours of proven field operation in all climates. MTBF (Mean Time Between Failure) for OSi instruments is greater than 80,000 hours. The APG® operates unattended 24 hours a day, 7 days a week. The instrument uses proprietary algorithms that eliminate the need for frequent calibration.
Field calibration every two years is typical. The APG® has AGC (Automatic Gain Control) to compensate for signal loss. The sensor also employs a comprehensive self-test that updates once per minute and reports any potential problems in the output message.
